A STRIDE FORWARD IN GREEN-GO WIRELESS

By Charles Phelps, Technical Support Engineer at Canford

The launch of the Stride Antenna marks a significant advancement for Green-GO, enhancing the performance and efficiency of the WBPX wireless beltpacks. This innovative solution enables true seamless roaming, allowing WBPX beltpacks to move fluidly across different antennas without interruption, thereby maintaining audio integrity and connectivity.

Featuring a user-friendly interface with an e-ink display and RGB LED indicator, the Stride Antenna improves usability by providing clear information on configuration and device status, even without power. Its outdoor-rated housing (IP53) and various mounting options (3/8”, M10, and VESA 100) allow for deployment in diverse environments.

Supporting up to five simultaneous WBPX connections, with a single pool capable of managing up to 100 wireless beltpacks and 250 Stride Antennas, the potential for scaling is substantial. However, careful planning is essential to accommodate higher device densities. The system operates on a first-come, first-served basis, meaning that any beltpack in the pool can connect to any of the associated antennas. For environments requiring prioritisation, bespoke pools can be established to ensure specific devices receive preferential access.

When deploying the Stride Antenna, consideration should be given to a spherical radiation pattern, ideally positioning the antenna centrally within the desired working area. It is suggested to maintain at least 1 metre of separation between antennas, and overlapping coverage should be accounted for in areas where roaming is expected. Factors such as reflective surfaces and audience presence can impact signal quality, making height and line of sight key considerations for optimal deployment. To assist in this, antennas can be switched to monitoring mode via the software, temporarily removing the selected device from the pool to visualise local DECT spectrum utilisation.

To ensure effective seamless roaming, connections between Stride Antennas should utilise IEEE 1588-2008 PTPv2 compliant switches to mitigate audio dropouts during transitions. While the broader network can include nonPTPv2 compliant switches, antenna connections to non-

PTPv2 switches may result in interruptions, indicated by alerts in the software and by the status LED on the Stride Antenna.

The PTPv2 timing tool provides a visual representation of synchronisation status through the control software, offering valuable insights that can help pre-empt potential issues.

With the new monitoring tools and intuitive interfaces, Green-GO enhances not only system functionality, but also aids applications in optimising performance. With

the capabilities for true seamless roaming and high device density, supporting the complexities faced by modern audio intercom systems. As users prepare for the rollout of this innovative technology, thoughtful consideration of deployment strategies and network requirements will be vital to fully leverage its advantages.

Canford Support Green-GO and Nova Lume at Prestigious American Football Games

By Charles Phelps, Technical Support Engineer at Canford

In October 2024, American football came to London which presented a unique opportunity for Canford Audio to showcase its partnership with Green-GO and Nova Lume, leveraging advanced communication technologies to enhance the game-day experience. The three games required a robust communication solution capable of supporting the intricate logistics of broadcasting and real-time coaching. The integration of Green-GO’s advanced communication features further enhanced operational capabilities. By incorporating scripting into their presentation, Green-GO streamlined user interactions, allowing coaches and staff transitioning from traditional telex devices to adapt more easily to this newer solution.

In light of the refined DECT (Digital Enhanced Cordless Telecommunications) space in the U.S., Nova Lume collaborated with Green-GO, Verizon, and Nokia to implement a solution utilising Long Term Evolution (LTE) modules. This setup allowed digital communications to operate over a private network, ensuring stable and reliable connectivity which is crucial for sporting events. When it comes to American football, no expense is spared. The unique context of the games demanded a complex, robust system which Green-

GO has been able to deliver. The need for reliability in communication systems during high-stakes events is paramount, as any lapse could significantly impact both on-field performance and broadcast quality.

The communication solution seamlessly integrates with coach-to-player technologies. Utilising discrete UHF modules embedded in player headsets, the system connects back to a radio interface, allowing coaches to communicate directly with players during the game. A key aspect of this setup is the ability to disconnect communications remotely when necessary, adhering to American football regulations regarding coaching interactions during specific periods. This feature highlights the balance between leveraging technology for competitive advantage whilst maintaining compliance with league rules.

The deployment of private networks, coupled with intuitive user interfaces and regulatory compliance features, illustrates a commitment to enhancing the efficiency and effectiveness of team communications. As American football continues to expand its international presence, the importance of reliable communication systems will only grow, making collaborations like this increasingly significant for ensuring success on a global stage.

Artificial Intelligence in Audio

By Paul Power, Technical Support Engineer at Canford

Artificial intelligence (AI) is being harnessed for use in many areas of modern life, including audio applications.

AI encompasses several disciplines in computer science which aims to mimic the human process of acquiring knowledge and understanding through experience and the senses.

Machine learning & Deep Learning

Machine learning and deep learning are two of the main processes used by AI. Machine learning uses simple, so-called ‘neural networks’ which contain one or two layers; an input layer and an output layer of nodes which are connected to each other. Neural networks mimic the way the human brain makes decisions by weighing up options to arrive at conclusions. Machine learning algorithms need to be trained using labelled data, and each node relies on a weighted threshold which, once exceeded, will pass the data onto the next node, hence develop learning and checking its accuracy through the so-called ‘loss functions’. Once

the algorithm is trained, it can then be called upon to execute tasks in minutes, compared to doing manually which would normally take hours. Compared to machine learning, deep learning uses a greater number of layers - typically thousands of layers. This means they can use unsupervised learning, enabling them to refine and tune their outputs for greater accuracy.

Sound Separation

Sound separation is the process of extracting a single sound source from a mixture of sources. When listening to a stereo audio track, human hearing has the ability to separate instruments in a mix and hone in to listen to specific parts of the stereo mix. This phenomenon was named by scientist Colin Cherry as the ‘cocktail party problem’ and is the focus of research in areas such as psychology, neuroscience, computer science, and biology. Human communication

requires listening to specific people in various environments and, in noisy environments, this can be challenging.

A good example of a sound separation algorithm in action can be heard here: https://community.sony.co.uk/t5/ discover-sony/let-s-talk-about-ai-soundseparation-technology/ba-p/3763081. Currently, Orcam, who originally developed a wearable technology to help people with vision loss, have developed an ear bud that allows the wearer to hear and have conversations in noisy environments, see here: https://www.orcam.com/en-us/ orcam-hear The earbud is connected wirelessly to a mobile phone running the custom app, utilising AI based algorithms. The phone is connected to a small dongle that contains several small microphones which, combined with the app, allows the wearer to select in the specific direction of the people taking part in the conversation, allowing up to a maximum of four

talkers at once. Once the talkers are identified, the app will then continuously track the talkers in real time, filtering out all the other noise in the environment in order to make the speech clearer and more intelligible. AI is also used in the latest TVs for sound separation tasks. There can be occasions within a film or TV programme when there are scenes that have a great deal of background sounds, which may conflict with the dialogue. Separating the audio into ambient, dialogue, and music components, allows each part of the audio to be processed separately, rather than as a complete mix. This includes tracking the vocals frame by frame in a film or programme where the scenes and sounds change dynamically. Utilising AI, the balance between the audio components can be adjusted, allowing the actors speech to be optimised for the human hearing range which provides better intelligibility.

Soundbars added to a TV offer greater sound reproduction than the TV’s speakers, but this means that you only use the soundbar, making the TV’s speakers redundant. Manufacturers are leveraging AI tech to allow the soundbar and the TV’s in-built speakers to work in harmony. For this to work convincingly, it involves precisely calibrating the levels between the soundbar and the TV speakers as well as ensuring timing accuracy between them, across many different programmes and films. AI processes the audio to play the primary audio from the soundbar and background

sounds from the TV’s speakers, which manufacturers claim adds depth to the soundstage. In addition, AI is used to compensate for the room’s acoustics, assessing the listening room and taking into account the distance between the TV and the walls and any pieces of furniture in the room, along with the position of the listener. This information is then used to consider the environment in which the viewer is sitting and process the sound to negate the environment’s effects.

Noise Cancelling

Traditional noise cancelling, or active noise cancelling, utilises subtractive algorithms which are limited in their function; they work by utilising the combination of an in-phase and a 180° out of phase signal. Subtractive algorithms are not dynamic and cannot work to provide 100% accuracy. AI algorithms are generative, rather than subtractive, as they can generate completely new signals with the interfering noise removed.

Active noise cancelling is used to filter out specific types of noise, primarily steady state low-mid frequency noises such as an airplane engine or traffic noise; so-called ‘deterministic’ signals. However, it struggles with higher frequency noise, such as speech or high frequency transient sounds. On the other hand, AI based noise cancelling can learn and adapt to different environments and noises and adjust their response to suit. A company called Avatronics have produced a so-called ‘True Wideband ANC’ solution using deep neural network techniques, which isn’t

limited to just low-mid frequency noise. This technology can provide a noise reduction of up to 30dB and up to 50dB at frequencies greater than 100Hz, a demo can be heard here: https://www.youtube.com/ watch?v=7oD7sMMdM4w&t=133s

As a result of microchip technology and low power processing, AI based noise cancelling algorithms are adaptable, efficient, and can be used in several applications - like hearables, smart speakers, smartphones, and voice conferencing systems.

Audio Perception and Testing

In audio technology and development, to understand how a process affects the audio it is necessary to implement subjective testing to provide critical feedback. There are several test methods that can be used which include MOS (mean opinion score) or MUSHRA (multiple stimulus hidden reference and anchor), but there are also other variations on these subjective tests. Particularly important nowadays is the performance of audio codecs and the fine tuning of these; especially since a lot of music/ TV/film is enjoyed through different streaming services. Further, as 3D audio in its different formats takes up large file sizes, development of audio codecs is ongoing to handle these formats and maintain audio quality.

Subjective testing is expensive, requires special rooms, equipment, and reliable listeners, and is time consuming. As a result, this is an area of continuous research to find ways that AI can be used to assess the audio in line with

human perception. The challenge is in training the model for audio evaluation, as a codecs output can vary in quality and there will even be peculiarities between different codecs. When training deep learning models in image processing, a commonly used data set is the MNIST database (Modified National Institute of Standards and Technology), which is a large dataset of various handwritten numbers from 1-9 which provides a starting point for training AI image processing. However, with respect to audio, there is no standard training set available due to the large number of random artefacts that can be introduced. As a result, research is ongoing to find methods of training AI models with the objective of predicting the subjective quality.

The measured sound level and the perceived sound level of sounds which vary in time and level at different frequencies, do not correlate well. Currently, researchers at Cambridge University have utilised deep neural networks to create a model that can analyse 12 hours of audio in minutes and is accurate to within 0.5 Phon - which is a very small margin of error, see here: https://www. enterprise.cam.ac.uk/wp-content/ uploads/2021/08/Marketing-SheetDeep-neural-network-for-perceivedloudness-calculation-Moo-3793-19. pdf This will have implications for the measurement of audio in broadcast, web conferencing, and product design and testing.

AI Future in Audio

Artificial intelligence is being used in numerous ways to process audio to provide better speech intelligibility, provide an enhanced listening experience, for audio testing, or to help the listener who may struggle in noisy environments. The use of Artificial intelligence has advantages over traditional signal processing methods as it can adapt and improve its output, compared to traditional algorithms that are created to do a set task. It is clear to see that AI has greater advantages over traditional signal processing methods, but AI will still require human input to train the algorithm, and to ensure sensible results.

EMO ON TOUR with Dave Taggart

By Adam Ironside, Marketing Manager at Canford

Dave Taggart is a session guitarist in demand! Currently on tour with Belinda Carlisle, Dave has previously toured the world providing guitar and vocals for Jimmy Nail and Danceclass among many others. He’s just wrapping up the UK leg of Belinda’s tour before getting ready to head off to the sunnier climes of Australia. I managed to catch him on route to the airport to find out why EMO is the first thing in his gig bag.

“ EMO DI boxes have always been the standard throughout my career. ”

I recently purchased another one and the banjo player in my bluegrass project said to me: ‘Where did you get that? Can you get your hands on one for me?’ They just have such a great reputation.

I’m using three or four different electroacoustic guitars every night and the EMO DIs are perfect; they are compact, noiseless, and ultra reliable. The ground lift has proven incredibly useful too”.

AN UPDATE ON AN ICON

By Graeme Lyon, Product Manager at Canford

There are few products as synonymous with Canford as the legendary ‘On Air’ sign. The bright red beacon remains commonplace in broadcast studios, radio stations, recording studios… and even in the homes of Canford employees!

Version 1 is a true icon! With its smooth, rounded glass fascia, it screamed 80’s. We have made thousands and thousands of these over the years. Because it was made of glass, it could get hot and the ceramic fixtures connecting to the baseplate were also subject to premature wear or breakage. (That said, there are still a lot of these in studios around the world!)

In the 1990’s came the first major update. We modernised the shape and started to make the classic red cover out of a much more durable (and lightweight) polycarbonate which would snap-fit over the base for a fast, tool-less installation.

Finally, in 2023, came the latest update – Version 3. The brand-new illuminated signs feature the same iconic aesthetic as the original and have been designed for maximum visibility: even when placed in a corridor, it is obvious if the light is on from all viewing angles. Version 3 also does away with traditional bulbs in favour of a much more energy efficient set of LEDs which are significantly cheaper to run, as well as providing a more consistent illumination.

It comes in two different versions:

Type A: Non-flashing, static on or off only.

Type B: Flashing can be set via an internal DIP switch (another improvement over the original which required a jumper header).

We only have one of the original Illuminated Signs left on site, which takes pride of place in the Canford Museum.

QUALITY

By Brian Smith, IT Services & Quality Manager at Canford

We’ve remained continually accredited for ISO 9001 since 1995! In 2017, I was asked to take on the role of Quality Manager with the main objective of ensuring a smooth transition from the BS EN 9001:2008 standard, to the new BS EN 9001:2015 standard. Since then, I’ve come to appreciate just how much work this is, and how vital it is to the healthy operation of many businesses around the world.

ISO 9001 is a globally recognised standard for quality management. The aim is to help organisations (such as ours) improve overall performance, meet customer expectations, continually improve processes, and demonstrate commitment to quality. Twice per year, we are audited by an external authority who not only ensure compliance, but also suggest areas for process improvement and ongoing optimisations - occasionally highlighting things that are sometimes easy to miss when you are so close to the action.

Being backed by a Senior Management team who believe in the value of the 9001 standard is imperative. Our management team is highly

collaborative, regularly addressing issues together and supporting cross-functionally to ensure positive customer outcomes. I’m also backed by a five-strong team who carry out internal audits according to the set schedule. I’m just here to facilitate; without their hard work and dedication, meeting these standards would be impossible!

We are proud to display our quality certificate and we work hard every day to ensure that standards are not just met, but greatly exceeded.

NETWORK TRAFFIC ROUTING

By Charles Phelps, Technical Support Engineer at Canford

In today’s complex network environments, effective traffic routing is essential for optimising performance and ensuring reliability. Strategies such as managing loops, handling trunks, and implementing redundancy are crucial for maintaining seamless data flow, which is vital for both business operations and user experiences.

Network traffic routing involves directing data packets from their source to their destination using various protocols and algorithms that identify the most efficient paths. One major challenge in routing is loops, where packets circulate endlessly between routers, leading to congestion and potential packet loss. This can severely degrade network performance, resulting in delays and increased latency. To mitigate loops, protocols like Spanning Tree Protocol (STP) create a loop-free topology by selectively blocking redundant paths, ensuring data travels efficiently while maintaining overall network stability.

High-capacity communication links, known as trunks, carry multiple signals simultaneously, connecting switches and routers for effective data transmission. These links are essential for scaling networks and supporting high-bandwidth applications. Equally as important is redundancy which

ensures reliability. By implementing redundant paths and devices, networks can maintain functionality even if a primary path fails. This is particularly critical in high-availability environments, where downtime can lead to significant financial losses and reputational damage. Redundant systems automatically take over in the event of a failure, enhancing operational resilience.

Precision Time Protocol version 2 (PTPv2) plays a key role in achieving precise time synchronisation across networked devices. Developed under the IEEE 1588 standard, PTPv2 allows synchronisation with sub-microsecond accuracy through a master-slave architecture, where a master clock sends synchronisation messages to slave clocks. This enhances data integrity in time-sensitive operations. However, establishing reliable communication can be challenging when devices are behind firewalls or Network Address Translators

(NAT). Hole punching facilitates direct connections by temporarily creating openings in the NAT, allowing PTPv2 to function effectively in complex network configurations. This technique is particularly beneficial for peerto-peer applications, enabling direct connections without relying on a central server, thus ensuring real-time applications operate smoothly.

To manage traffic efficiently, organisations employ queuing strategies such as FIFO (First In, First Out) or priority queuing, ensuring that highpriority packets receive the necessary bandwidth. Policing is also vital, as it involves monitoring traffic flow to ensure compliance with bandwidth limits and preventing any application from monopolising resources. Resource-sensitive networks prioritise efficient bandwidth use, especially when traffic demands fluctuate, while Link Aggregation Group (LAG) enhances throughput and provides redundancy

by combining multiple connections into a single logical link. This technique helps balance loads, reducing congestion risks and improving overall network performance during peak usage times. Additionally, port forwarding allows external devices to connect to specific services within a private network by configuring routers to forward incoming traffic on designated ports to internal devices, facilitating remote access to services while maintaining network security.

Effective network traffic routing and management require a comprehensive approach that encompasses these various strategies. By addressing loops, managing redundancy, implementing PTPv2 for precise synchronisation, and utilising hole punching for direct

connections, organisations can prevent packet loss and minimise latency. Identifying possible bottlenecks before they effect service quality is essential. Techniques like traffic shaping and bandwidth reservation ensure that critical applications receive necessary resources while less critical traffic is throttled, maintaining optimal performance across the network.

Canford in the Community

By Alan Wilson, CEO at Canford

Since our inception, Canford have always championed and engaged with children and young people in our area. The North-East is renowned for engineering and manufacturing. At one time, we were home to some of the biggest shipbuilding operations in the world. The legacy continues today with major car manufacturers, innovative technology companies, and all other manner of manufacturing businesses being based in our region. What is in short supply, however, is an interest in STEM careers amongst our young people.

It has been a known issue for years now, but recent research commissioned by the Royal Society in partnership with EngineeringUK (undertaken by Verian – formerly Kantar Public) suggests a further downward trend since 2019. 7,000 secondary-aged young people were surveyed as part of the Science Education Tracker. The full report can be downloaded here:

https://royalsociety.org/newsresources/projects/science-educationtracker/

STEM.org.uk picked out some key points from the 181-page report:

Hands-on practical work in schools has diminished. Only 26% of students reported doing practical work at least fortnightly (down from 44% in 2016) – leaving a gap between theoretical knowledge and real-world application.

While interest in science careers has increased since 2019, there was a decline in the percentage of younger students aspiring to learn science beyond GCSE; almost a third of young people in years 7-9 already rejecting science beyond GCSEs.

Access to career information and work experience has declined, but it isn’t just through lack of interest. Indeed, 26% of young people reported wanting to secure STEMrelated work experience but had not been able to do so; a worrying statistic when considering that T Levels require around 45 days of workplace experience.

What does this mean for

Canford?

At heart, we are a manufacturing and distribution business. Children are always amazed by the sheer volume and spread of ‘engineers’ that we have on site. We have mechanical engineers, test engineers, quality and assurance engineers, production operatives, product research and design, technical support engineers... and many more! Without a secure pipeline of young people interested in STEM careers, Canford would cease to exist. It is already estimated that there is a job gap of around half a million roles to be filled supporting the green industry alone.

What are we doing about it?

We’ve always done our best to support local schools and STEM engagement events but I, and the board, felt like we could do even more.

This is why we decided to revitalise and re-enthuse our approach in 2023. We tasked Adam, our Marketing Manager, to put together a team of Canford Ambassadors to go out into our communities, engage with young people, and evangelise careers in STEM at companies like ours. At the heart of this is collaborating not only with schools and education providers, but also with other engineering companies in our region to ensure we are doing our collective best.

The team came up with a brandnew mission document, strategy, and approach and have already made some great inroads, but there is still a lot of work to be done. Of course, resource is finite, so we’ve partnered with several local schools to provide handson activities as well as our guidance and expertise. As our team inevitably grows, so too will the number of schools we can partner with.

Our three key pillars of our outreach strategy are:

1. Value time and experience over sponsorship.

Our team has hundreds of years of priceless collective experience. We are still open to financially sponsoring events and projects (and these are evaluated on a case-by-case basis), but we prefer to share our time and experience with young people, providing hands-on experiences and learning opportunities. We attend career’s fairs, run workshops and guest seminars at schools, and bring select groups into Canford for a full, interactive site tour.

2. Include everyone.

Adapt our content and activities to suit all skill levels, abilities, and learning styles. We’ll include children and young adults of all ages, socio-economic backgrounds, etc. This means we will work with all interested parties where time and resources allow.

3. Support education providers. Explore opportunities where our Subject Matter Experts can contribute to the development and design of school and further education curriculums; ensuring students are learning the skills that the industry

needs. This is an incredibly ambitious goal, but one that we are making some early progress on.

I’m incredibly proud of the work we have done so far. Not everyone we meet will go on to work at Canford, or have a career in STEM, but what we can guarantee is that our team of Community Ambassadors are making a life-long impact on the young people that they interact with; many of our activities are about problem solving and teamworking, two of the most transferable skills I can think of.

If you think we can support your event or organisation in any way, I encourage you to get in touch with Adam and the team.

From Blue to Green

By Jen Cassidy, Creative Designer at Canford

Being Green has always been in our DNA. In Source Material 8, I snuck into one of the monthly meetings hosted by the Green Group to find out more about the latest eco-initiatives that were happening around the business. I reported on some of the things that the team were up to, things like:

• Replacing all of our lighting with energy-efficient LEDs. These use only a third of the energy we were previously using, and without giving off any heat. The LED bulbs also last significantly longer than incandescent bulbs, greatly reducing the amount of waste that we generate.

• Installing PIR / motion-detection lighting in all communal areas (and we are currently trialling this throughout other areas of the business).

• We’ve had boiling water outlets in communal kitchens for a while, replacing the need for energy-hungry and inefficient kettles. We recently upgraded all five of these to ‘smart’ versions which are programmed to only run during business hours.

• Installing a wildlife garden to provide a habitat for local wildlife.

• Plus, many other small changes to our business that all add up.

I also found that our warehouse and logistics teams were heavily involved.

• Transitioning over to pure recycled and recyclable air-fill packaging. Our newest air-fill packaging contains no virgin plastics whatsoever and can, in turn, be entirely recycled…multiple times over.

• Exploring options to eliminate plastic use altogether by using alternatives such as paper and compostable “plastics” made from renewable sources (such as wood pulp). As well as sending small fixings in paper bags instead of plastic.

• Using card end caps (as opposed to foam inserts) and paper hex-cut wrap instead of foam or bubble wrap.

• Working with our logistics partners to make use of carbon-offset shipping wherever possible, at no additional cost to our customers.

All of these seemingly little things really add up and go a long way to reducing our carbon footprint and impact on the environment. However, the biggest project was yet to come.

Operation: Solar

The work began in Autumn 2022 and was completed in early 2024. It was a huge job. The entire roof needed to be replaced and reinforced, safety mechanisms and access and escape points needed to be installed, our Facilities team needed to be trained on basic maintenance and routine care, and it all had to be done without a single day of down time. The work and disruption was well worth the effort. In the last few months alone, we have already

generated over fifty percent of our own electricity, and we’ve barely had any sun! As a next step, we are exploring how to incorporate a storage solution so that we can harvest the sun’s energy during downtime to further reduce our reliance on the grid.

In summary, we have produced over 50% of our monthly electricity usage since our system was installed!

Looking Forward

Now that this job is completed, the Green Group are researching what other high-impact projects we could embark on next. This includes:

• Thermally insulating, and cladding, exterior walls.

• Installing rain harvesting and water reuse systems.

• Improving glazing insulation.

• Installing electric vehicle charging points (to encourage employees to invest in electric vehicles).

Each of these projects has contributed to dramatically reducing our energy usage. Not only are we now generating over 50% of the electricity we use, but we are only using a third of the energy we were using just three years ago! The whole Canford team feel a great sense of pride at what we have achieved thus far, and the ideas keep on coming…

Stats

Number of Solar Panels - 296 (producing a 124.32kWp system)

Projected Annual Yield - 102-120MWh/year

Actual Yield to Date (February to August) - 85.118MWh (an estimated saving of £37,367)

Canford WIN at the Sunderland Business Excellence Awards

By Mark Brindley, Operations Director at Canford

Two years ago, I wrote an article for Source Material 8 detailing how pleased we were that one of our young apprentices, Lucas Foulk, won Apprentice of the Year at the prestigious Sunderland Business Excellence Awards. This year, we were nominated again…

We were entered into the category of Sustainable Initiative of the Year for the work we have done to our building in the past twelve months, with a particular emphasis on Operation: Solar - which Jen has detailed in her article From Blue to Green.

Well, I’m delighted to announce that, despite facing some serious competition, we won! Operation: Solar was a massive undertaking, and huge

thanks must go to Karl Thoroughgood (Site Services and HSE Manager) and Dylan Tindall (Site Services Coordinator) for their commitment, perseverance, and attention to detail; keeping the project running as smoothly as possible from beginning to end. Thanks to the work of Site Services (and everyone at Canford), we are now using just a third of the energy we were a few years ago, and we are generating over half of that ourselves.

A massive congratulations is in order to all of those who came very close runners-up. It gives me huge optimism for the future of industry in Sunderland to see so many environmentally conscious individuals and companies doing everything that they can to

make Sunderland green. We’ve all got a long way to go but, together, we can ensure that the unique landscapes of Sunderland remain protected for future generations to enjoy.

Keeping Elliott House up and running is no easy task. Unassuming from the outside, Canford HQ is a sprawling complex set over two floors. Karl and Dylan are responsible for everything from large projects, such as the aforementioned Operation: Solar, to car park maintenance, site security, and routine building checks. Our Site Services and Facilities team keep us safe and secure, and ensure that we are doing everything we can to minimise our impact on the environment. Keep up the great work team!

CABLING MATTERS, POWER BUDGETING

By Charles Phelps, Technical Support Engineer at Canford

Since the early 1980s, the Technical Projects “Tecpro” range of intercom equipment has been enhancing communication across various industries and applications. This range consists of interoperable hardware devices that provide “two-wire” solutions, often referred to as “party line” or “ring” systems. These enable multiple users to engage in full-duplex conversations on one or two channels. Tecpro power supplies and master stations serve to power and connect outstations such as belt packs and loudspeaker stations. Most devices feature 3-pin XLR inputs and outputs, allowing for straightforward daisy-chaining. Alternatively, a central one-in, multiple-out signal splitter can be employed, with both methods often combined.

Termination in a system is essential for maintaining stability and balancing the combined impedance of the installation. Without proper termination, the overall load of the system

would dictate the conversation level, resulting in undesirable audio artifacts during use. Conversely, excessive termination points, sometimes known as “double termination,” can adversely affect system performance, lowering audio levels and reducing the maximum number of devices that a given power supply or master station can support.

When selecting cabling, two main factors must be considered: the number of outstations and the length of the cable runs. Generally, as the number of outstations increases, larger cables are required. A 0.5mm² (20AWG) twin-screened cable, such as Canford heavy-duty cables (FST-HD, HST-HD, HST-HD-R), is recommended for greater flexibility. For shorter runs of up to approximately 150 metres, a smaller cable size of 0.22mm² or 0.25mm² (24AWG) is typically sufficient, provided that no more than about 12 outstations are connected (Canford types FST, HST, and HST-R). For very short runs of just a few metres serving a single station (e.g., between a wall connector and a belt pack), the core size is less critical.

A Tecpro Series 2 power supply (MS741/5, PS751/2/4) can provide up to approximately 2A, shared across multiple rings where applicable. Most devices consume around 10mA at idle, while belt packs peak at about 50mA and loudspeaker stations at approximately 200mA. Thus, neglecting cable loss, a single power supply could theoretically support around 20 belt packs or four loudspeaker stations. However, factoring in total cable length, these theoretical maximums may be halved at approximately 1km. To increase available current in a system, multiple power supplies, boosters, or master stations can be deployed, but care must be taken to avoid double termination, typically positioned at the furthest points. This allows for an increase in total system cabling and the number of outstations.

Interconnections are usually made via 3-pin XLR connections (pin 1 Ground, pin 2 V+, pin 3 Comms), making Tecpro systems unbalanced. While this configuration facilitates efficient signal flow and integration, it is susceptible to interference, particularly over longer distances. To achieve a balanced “four-wire” system, line isolating transformers

RELIABLE WIRED INTERCOM

Comfortable: Lightweight design and clear, intelligible audio for fatigue-free communication.

Reliable: Easy to operate, universal power supply (for world-wide use), and renowned for toughness and durability.

Versatile: Connect between two and hundreds of users on up to two independent intercom rings.

like the AD903 can be used, translating communications effectively. However, this conversion is generally DCblocking, meaning that power and termination must be provided on either side of the balanced cable run.

The Tecpro intercom range offers a robust solution for various communication needs across multiple industries. By carefully considering factors such as termination, cabling, and power supply configurations, users can optimise system performance and ensure reliable communication. With its flexible setup options and compatibility with a range of devices, Tecpro continues to be a great choice for effective intercom solutions.

Know the basics about phantom power

By Eddy Bøgh Brixen, DPA Microphones

All condenser microphones need power. Phantom power is the primary standard for professional microphones. Here are answers to 10+ of the most frequent questions about phantom power and its use in microphones.

WHAT IS PHANTOM POWER?

The short version: Phantom power is the standard method for powering professional condenser microphones via the XLR-3 connector and balanced cables. The XLRconnector’s pin 2 and pin 3 both carry +48 volts ±4 volts DC. Pin 1 is 0 volt.

The name “phantom power” refers to the “invisibility” when connecting balanced microphones that do not need external power, like dynamic (moving coil) microphones. In short, the name is P48.

WHY DO MICROPHONES NEED POWER?

Only microphones with built-in electronics need power. That is primarily condenser microphones. However, specific dynamic microphones (ribbon mics) with electronics also apply phantom power.

IS IT STANDARDIZED?

An international standard describes phantom power to secure that the connection works as intended across all brands. The standard IEC 61938:2018 outlines the technical specifications. These specs concern the voltage, the current draw, the impedance, etc.

IS PHANTOM POWER ALWAYS 48 VOLTS?

Given the IEC standard, all new phantom-equipped products (recorder inputs, mixer inputs, preamps, etc.) should provide 48 volts. However, it has previously been an option for designers to choose between 12 volts or 24 volts. So, there are systems out there providing less than 48 volts. Even 15 volts and 18 volts systems exist. Sometimes a device only indicates the application of phantom, but not the actual voltage.

WHAT IF THE VOLTAGE IS LESS THAN 48 VOLTS?

Most professional phantom-powered microphones need 48 volts. (A few brands can work with 9-52 volts). When you have a P48-microphone, it may still work at a lower voltage. However, the typical result is that the microphone’s performance is affected, reducing the max SPL handling and increasing distortion. If the voltage is too low, the microphone will stop working.

Figure 1.

Figure 2. IEC Standard 61938:2018

HOW MUCH CURRENT CAN YOU DRAW?

The IEC standard specifies that the rated available current of P48 is 7 mA, and 10 mA is the maximum.

MUST THE P48 BE SWITCHED OFF IF I DON’T USE IT?

Basically, it is not necessary to switch off phantom power (this is why it is called Phantom). However, it is also a question of the input-device facilities. Some devices have switches individually per channel. Others are equipped with one single button connecting/ disconnecting all channels simultaneously.

WHAT IF MY DEVICE DOES NOT HAVE PHANTOM?

There are various options if you have a recorder, mixer or amplifier without phantom power and a microphone that needs it. If you are on the go, you may need a supply unit that works via batteries. In the studio or on stage, you can use a mains-connected phantom-power unit.

DO MINIATURE MICROPHONES ALSO NEED PHANTOM POWER?

Yes and no. Most miniature microphones are designed to work in connection with wireless transmitters, which are limited to providing less than 10 volts. Further, the transmitters are not equipped with XLR-connectors, so it is not possible to provide P48. However, there are adaptors available, that convert P48 to the voltage relevant for making the miniature microphone work. DPA miniature microphones connected via an adapter (DAD6001) work in the range of 12-48 volts.

Figure 3. Adapter for DPA miniature microphones.

HOW IS IT POSSIBLE TO CARRY BOTH AC AND DC?

One of the intelligent things about P48 is that the wiring scheme brings DC to the microphone – and the same wiring brings the signal back to the input. Think of it like the sea: We have a water level (the DC), and in addition, we

have waves (the AC, the signal). So, you can say that the DC is moving up or down, modulated by the AC.

CAN P48 POWER ANYTHING ELSE BUT MICROPHONES?

P48 can power other devices than microphones, i.e., line drivers. It is sometimes used for powering work lights.

WHEN WAS PHANTOM POWER INVENTED?

Phantom power was invented in 1966 by Neumann in connection with a special delivery to NRK (Norwegian Broadcasting), where 48 volts were available for a lighting system. The first standard was DIN 45 596 (now superseded by the IEC 61938:2018).

CAN PHANTOM POWER DAMAGE A MICROPHONE?

If an unbalanced and sensitive microphone – like a ribbon microphone – is connected, it may get damaged. So never connect unbalanced microphones or cables to phantom-powered inputs.

HOW TO CHECK THE PHANTOM POWER?

A straightforward way to check the phantom power is using a voltage meter. One test probe to pin 1 and the other to pin 2 or to pin 3. It should read 48 volts DC (and 0 volts AC) in both cases. Between pin 2 and 3, it should read 0 volts. The 48-volt reading is the open-circuit voltage before connecting the microphone. When connecting a microphone, the voltage drops to a lower value due to the current draw through the feeding resistors.

Figure 4. Basic Phantom power circuitry.

A signal generator like the NTI-Audio MR Pro Minirator reads whether the output “looks” into a P48 input (i.e., a microphone input). Also, various “gadgets” or tools are available, like the Canford P48-Check Phantom Power Tester.

Figure 5. 25-063 Canford P48-Check Phantom Power Tester.

DOES P48 CIRCUITRY HAVE ANY EFFECT ON THE INPUT IMPEDANCE?

Any input has an input impedance. As a rule of thumb, the load (input impedance) should be 5-10 times higher than the source impedance. For example, having a microphone with a 100 Ω output impedance, the load should be at least 500-1000 Ω. That is not a problem with phantom-powered input, where the input impedance is 3.4 kΩ. However, a dynamic microphone with a nonlinear output impedance (i.e., a coil) usually prefers a much higher input impedance. Thus, it is a good idea with a particular high ohmic impedance for dynamic mics.

HOW MUCH CURRENT DRAW CAN YOU EXPECT FROM A MICROPHONE?

The microphone design determines the current draw. Here are some typical values:

Histibe Transforms Sounds of Oppression into Tools of Expression with Rycote Microphones

As far as I know, there are no other brands making something on this level.

Maks Histibe is a polymath whose talents encompass music production, synthesis, filmmaking, DJing, sound design, and field recording. Known professionally by his stage name — a combination of the words HIStory, TIme, and BEnd — he has built a career around both audio and visual media. The former includes sample packs and sounds for a range of music software brands; the latter involving filming and directing of original video footage from all over Ukraine for international artists and labels. His virtual instrument, Swords to Ploughshares, turns field audio related to the Russian invasion into playable musical sounds. Throughout the sometimesharrowing process of recording the source material up close, he has found Rycote microphones and protective gear match his own tenacity and agility. These include two CA-08 cardioid mics and a BD-10 figure-eight mic, residing in either a Cyclone basket system or Classic Softie windscreens. Histibe took a valuable moment of stable internet access to share his important work with us via Zoom.

Your most recent project is unique among music software. Describe it in your own words. It’s my virtual instrument, which is called Swords to Ploughshares. Since the invasion began in 2022, I have been recording a lot of sounds from everyday existence in Ukraine, from city ambiences to explosions and air raid alerts. At first it was to document them, then with the help of my friends at [sampleware developer] SoundIron, we put it together into a virtual instrument for [Native Instruments] Kontakt.

This way, everyone who has access to a DAW that can run plug-ins can use these sounds as the basis of melodies, pads, bass lines, or percussion. The object was to take what were originally sounds of destruction and turn them into a tool of creation.

Other than this, I am also working on my own music. I just released my new single called ‘Future in Our Hands’ from my upcoming album Metal Sunrise. It’s an electronic track with an accompanying video, meant to inspire people to realize they have the power to change the future. Even small actions can turn into a large tide when many people perform them.

I also hope to release a full album this year. I have 12 tracks ready right now. So, it will be a mix of electronic music, my own vocal experiments, and cinematic themes.

What Rycote equipment do you use?

I’m using their cardioid [CA-08] and figure-eight [BD-10] microphones. I have two cardioids, and one figureeight microphone, along with a set of

Cyclone shields to cover them. I often use them all together on a mount that holds all three. I know Rycote started out making windscreens and other protective equipment, but I’ve really come to like their microphones. There’s a depth to their sound that really helps me keep up the level of quality in the field. And their compact size, because I can maneuver very quickly, which sometimes I have to do. This is all based on my testing stuff in the field, not just because you’re interviewing me. I am genuinely impressed by the quality of Rycote equipment.

What are some more challenging sources you have used them on in the field?

Some of the sounds in the Swords to Ploughshares library were recorded during air raids. I run the mics into a Sound Devices MixPre-6 II, which can record in 32-bit floating point audio resolution. I need that because if there is a loud explosion, sirens, anything like that, it is impossible to predict what the levels will be. When you have 32-bit, you can almost forget about gain in general — just set it to a working midpoint.

Do you think the mics help with this or is it all about the audio interface?

The mics definitely contribute because they have excellent dynamic range. They can soak up all of the differences between loud and soft that are why I need the 32-bit recorder, and still

have a clean but warm sound. Then, I can also take them into a conventional studio environment to record instruments. I like to use the cardioid mics in X-Y stereo position, but then add the figure-eight as an additional channel to capture the sound from the sides. This gives me a character I like for my sample packs.

Do you use any other protective equipment from Rycote?

I like the Classic Softie windscreen. It includes a rubber mount that holds the mic very securely and it’s all one piece, so very quick to set up. For when you have a very strong wind, the Cyclones just can’t be beat. And I’ve heard the company is working on a Cyclone you can put two mics in — I mean, they have them already, but this one is specifically for their mics. I want to get one of those and use it on mid-side recordings, where I would use one cardioid and one figure-eight. As far as I know, there are no other brands making something on this level.

Tell us a little about your background. How did you come to develop your own sounds?

I’ve worked in sound design for over ten years. I’ve done sounds for several brands in the music production world: Arturia, FL Studio, Loopmasters, Output, and a few more. So, I was able to build a portfolio over this time. But then I realized I wanted to create my own thing, which led to

the collaboration with SoundIron and Native Instruments. As I said, what is happening in Ukraine is terrible, but it gave me the opportunity to try and make something positive out of it.

On that topic, what is one of the scariest things you recorded?

Last year in Kyiv there was a situation where fragments of a drone fell onto an apartment building not 500 meters from where I live. I recorded the sound as I had already been working. It was like nothing I’ve ever heard. I looked at the building the next morning and there was a giant hole in it.

What is it like to try to make art when you are continually under attack and your daily environment could be dangerous? What is the role of the artist?

It’s difficult to make art right now. When the invasion started in 2022, I became very depressed. Mike Peaslee from SoundIron emailed and said, “Why don’t you just try to record everything going on around you?” That was how the virtual instrument Swords to Ploughshares got started. Slowly, this actually helped me refocus and deal with all the heavy emotions. Here, we constantly live under fear of air strikes, and you don’t even know if your city might be invaded the next day. It’s like a war movie. What keeps me going is the sense of purpose this gives me. Also, if someone likes the virtual instrument, maybe they will check out my music.

You asked about the purpose of the artist. In my case, I feel that turning the pain and fear going on around me into a musical tool that people can use, that shows the world that we are resilient here. That life goes on, and we will heal.

Prioritising Our People: Our 2024 Wellbeing Committee

By Beth Routledge, HR Manager at Canford

One of our top priorities in 2024 has been the health and wellbeing of our people. With this focus in mind, our newly appointed Wellbeing Committee have been dedicating their time towards creating a supportive and thriving work environment.

In today’s fast-paced world, wellbeing in the workplace is no longer optional - it’s essential. We’ve seen firsthand how prioritising physical, mental, and emotional health leads to happier, more engaged teams, increased productivity, and stronger collaboration. Our ongoing aim is to make sure that our employees feel valued and supported, not just in their work, but in their overall wellbeing. With that being said, we are excited to share our top FIVE wellbeing campaigns from 2024…

1. Canford Easter Egg Appeal for Grace House Northeast

Our Easter egg appeal for Grace House Northeast was a tremendous success, with generous contributions from our employees. The appeal collected a wide variety of Easter eggs which were donated to the children and families supported by Grace House. This initiative brought smiles and joy during the Easter season, reinforcing our commitment to supporting local causes and making a positive difference in the lives of those in need.

Harry Forster from Grace House: “The collection will be distributed across

our services to the children and young people who attend our youth groups, social groups, counselling, and work experience. The groups will either enjoy the treats in their sessions, or they will use them to do some cooking or baking activities”.

2. National Pet Month

We recently celebrated National Pet Month, creating a unique opportunity for employees to come together and share their love of animals. Through a series of fun pet-themed activities, including a photo-sharing contest, colleagues bonded over their furry companions! This celebration not only highlighted the importance of pet care, but also strengthened our workplace community by encouraging teamwork and light-hearted interaction. Congratulations to Mark Carswell, Systems Administrator, who came first place for his lovely picture of Kali the kitten!

3. Promoting Men’s Health

We are dedicated to promoting men’s health and encouraging open conversations around mental wellbeing. As part of our efforts, we recently hosted an awareness session with Andy’s Man Club, a crucial

organisation that encourages men to speak openly about their mental health. This session aimed to break the stigma surrounding men’s mental health, providing a supportive space for honest discussions and highlighting the importance of seeking support. We also collaborated with Washington Mind who shared a powerful initiative with us, Ray’s Corner, which focuses on raising awareness about suicide in men. This campaign highlights the importance of recognising the signs of mental health struggles and providing support to those in need.

4. Wear It Green Day

Washington Mind is our nominated charity for 2024, and we kicked off our meaningful partnership by hosting a “Wear it Green” day to raise awareness for mental health. Our employees happily participated, dressing up in green attire to show their support for this important cause.

5. Canford Garden Gang

We launched “Canford’s Garden Gang” earlier in the year, which is aimed at enhancing our company garden and promoting local wildlife. This initiative is part of our ongoing commitment to creating a greener, more sustainable workspace. Through this club, employees will have the opportunity to collaborate on garden projects that support biodiversity, attract pollinators, and create a thriving environment for native species. By fostering a connection with nature, we hope to enrich both our workplace and the local ecosystem.

A Trip to the Canford Museum

By John Driver, Head of Fibre & Design at Canford

At the beginning of this year 2024, I celebrated forty years at Canford! People can’t believe it when they ask it, but the time has really flown over and I still enjoy it. Every day is different and brings with it a new set of obstacles and challenges to overcome. It has been a real pleasure working with everyone and seeing both the team and the company grow over the last four decades. I’m not going anywhere just yet though; they aren’t getting rid of me that easily.

Eight years ago, in Source Material 2, Iain wrote an article about some of Canford’s legacy products. Feeling slightly nostalgic as I reflect on my forty years, I took a walk down to our small in house museum which has a collection of some really cool Canford and industry antiquities.

The Canford Museum is also home to a number of early NEAL tape machines, tapes, Panamic pieces, and all other manner of bits and bobs. Oh, and let’s not forget the legendary Illuminated ‘On Air’ signs which Graeme took a look at elsewhere in the magazine, a big sigh of relief all around when we went to plastic - shipping the original glass ones was a nightmare!! Maybe we’ll take a look at some of those next time…or… look out for Canford’s 50th anniversary in 2026: we might just bring some of them out to the shows for you all to reminisce.

Neutrik 3300 Audiograph System

This is cool. The 3300 Audiograph System dates back to 1982 and was a digitally controlled, precision audio analysis system. It was fully modular, with various units available, and printed hard-copy function plots / graphs. It’s heavy, but it is portable and was sometimes used in room acoustic analysis, noise-level logging, and in laboratories and product design.

Microphone Splitter

Simple in concept, the humble mic splitter is all about high quality, high performing components. This version from the early 80’s featured a UK Sowter transformer and appeared in our first catalogue back in 1981. These were available as multichannel versions too and we went on to sell thousands of these throughout the 80’s building various custom units for local TV and Radio stations. Quite often on a Friday, a call would come in from Tyne Tees TV who would urgently need another couple of 8ch mic splitters for the “Tube” - which you may remember was a ground-breaking music show shot live from Tyne Tees TV studios. Sometimes, they’d even send a taxi would be sent to pick them up and get them over to the studios in time. A lot of the big musicians in the 80’s launched their careers via the “Tube”, and to think we helped them a little on the way...

Universal AVOmeter Model 8 MK2

Like something from an Indiana Jones movie, the AVO 8 was a ubiquitous, analogue general purpose multi-meter. Any good engineer would have had an “AVO”. This MK2 version likely dates back to the mid-60s but Universal continued to make a version of these right up until 2008.

Canford ProInterface MK1

Another large, heavy relic from days gone by. The ProInterface was a bi-directional, stereo interface designed to connect ‘semi-pro’ equipment, such as cassette recorders and DAT machines, in a more professional studio environment. Although now discontinued by Canford, similar products are still being used to interface products in today’s studios.

Canford Automatic Cable Tester MK2

We are up to MK4 these days, and it is easy to see why. The MK2 version is big and heavy, but brilliant in its own way. It features a heavy duty, rechargeable battery, and an LED array that highlights all of the most common faults - including checking for phase and for the presence of phantom power.

AUDIOPRESSBOX STEALS THE SHOW

By Gavin Drake, Sales Director at Canford

It’s sometimes a little difficult to get excited about exhibitions. Don’t get me wrong, I always look forward to catching up with colleagues and friends and seeing what exciting new technology the industry has to offer but, when you are so close to our products day-in, day-out, it is easy to forget just how brilliant some of them are.

Earlier this year, we became UK distributor for AudioPressBox. We knew right away what a clever, innovative, and affordable product this was, but what I didn’t expect was just how much engagement we would receive at IBC because of it. Taking pride of place at the front of our stand, AudioPressBox caught the eye of hundreds of passersby. It shouldn’t really have been a surprise as press boxes have become increasingly popular recently.

Press boxes eliminate the need for multi-mic setups; crews can simply turn up and plug into one of the channels of the press box (if this hasn’t already been done for them). This makes last minute conferences much easier, much safer, and far more efficient than ever before.

Just before IBC, AudioPressBox released their most affordable offering yet: the APB Mini. The APB Mini is the World’s smallest active professional press box, but don’t let the size fool you; the APB Mini is chock full of features.

APB Mini (APB-312C-USB)

• 2 Analogue Mic / Line inputs (balanced) with phantom power and 26db pad.

• 1 Digital USB-C input and output.

• 8 Analogue XLR balanced & individually transformer isolated outputs.

• 4 Digital USB-C outputs.

• Built-in compressor and limiter for analogue (XLR) inputs.

The heavy duty Nanuk case makes this suitable for indoor or outdoor use and the USB-C also allows for a video conference in & out connection for a hybrid press conference.

Available in a variety of colours.

As ever, our Sales and Technical Support teams are fully trained in all things APB and experts in their extensive product range. Whether you are looking for your first press box, or expanding your growing collection, we are here to offer advice on the best possible product for your needs.
