MEYER SOUND CAL Designed primarily for vocal reproduction in fixed installations, Meyer Sound’s CAL loudspeakers produce a vertical beam of programmable width and then digitally steer the beam’s pattern up to 30º up or down for best intelligibility. CAL comes in three models - 32, 64, 96 - each providing a different maximum output level over an operating frequency range of 100Hz to 16kHz. A single, unobtrusive CAL loudspeaker can provide clear vocal reproduction over a large area while minimising undesirable reflections. CAL is a great choice for stadiums, sporting venues, airports, convention centres, places of worship, shopping malls, retails spaces, and reverberant spaces requiring low-profile sound reinforcement for voice reproduction. As the first loudspeaker to claim AVnu certification, CAL will have seamless interoperability with certified AVB devices from other vendors, and offer numerous advantages of the open IEEE AVB standards. Flexible mounting options allow users to mount CAL loudspeakers against walls or columns, and custom colours ensure they will blend into any background. Weather protection is standard and permits outdoor installations, making it easy to integrate CAL into any environment. www.meyersound.com

KV2 AUDIO SWEDEN WORLD CUP FAN PARK Fremlab AB, KV2 Audio’s long-term partner in Sweden, played an important part in the recent madness kick-started by Sweden’s progress at the 2018 World Cup. This all began with the ever popular event, SM Week, which takes place every year in summer and winter at different locations in the country. The traditional event aims to increate interest in Swedish sport. In 2018, the location of SM Week was in Helsingborg and Landskrona taking place from 2-8 July. On 3 July 2018, the organisers decided to show organise a fan park for Sweden’s World Cup match against Switzerland, using 15 sq metre LED screens for an expected audience of 1,000 fans. Gröningen Park was suddenly flooded with more than 10,000 people and the original plan to have just two NEXO 12-inch loudspeakers as FOH needed quickly re-thinking for

the next game against England on the 7 July, where one KV2 VHD2.0 mid/ hi per side were added to the original set-up with a pair of KV2 VHD4.18 18- inch subwoofers for added low frequency reinforcement. Given the results from the first match Fremlab SE was again hired in by Tylösound to provide a VHD system with four KV2 Audio VHD4.18 subwoofers as the main FOH system covering a crowd of 15,000 people. Having suffered defeat to England, attentions turned to a homecoming ceremony for the return of the squad. The ceremony took place on 11 July, where the VHD System (with two delay points at 40-metres and 80-metres comprising of original RCF Event6000 cabinets designed by KV2 Audio’s Head of R&D, George Krampera) was again deployed for speeches by the city mayor and Helsingborg FC chairman in front of 10,000 people. www.fremlab.se | www.kv2audio.com

APART AUDIO METHLEY CRICKET CLUB Methley Cricket Club, founded in 1863 in the village of Methley near Leeds, UK, is home to two senior teams playing in the Bradford Cricket League, as well as five junior teams playing in the Heavy Woollen Cricket League and the Leeds & District Cricket League. The cricket ground at the club has also hosted the Jack Hampshire Cup Final on many occasions. The audio system at Methley Cricket Club needed an upgrade to allow for announcements to be made outside on matchdays and for background music and announcements in the bar / function suite. An Apart Audio system was selected to allow two separate zones of audio, with MASK6CT-W loudspeakers inside the building and MPLT32 two-way, long-throw horns used outdoors. Powering the new loudspeakers are Apart Audio’s PM1122 and REVAMP4120T amplifers. As well as the new audio system, there is also a radio mic and multisource music player as sources - both of which are controlled from a pair of Apart Audio’s PM1122RL wall control panel. www.apart-audio.com

MARTIN AUDIO LEE VALLEY HOCKEY & TENNIS CENTRE Old Barn Audio (OBA) has completed its fourth high-profile project for the Lee Valley Regional Park Authority, equipping the Lee Valley Hockey and Tennis Centre at the Queen Elizabeth Olympic Park in London with a customised Martin Audio CDD-WR PA system. The £30m centre was opened in June 2014 and consists of two outdoor hockey pitches and four indoor and six outdoor tennis courts. The primary hockey pitch has a capacity of 3,000, which can be increased to 15,000 for major events. The requirement was to make the centre ready for a number of high profile international events, starting with the Hockey Women’s World Cup, after which the PA system will be reconfigured and extended. OBA Project Manager, Neil Kavanagh said his company entered into a fiercely competitive tender and provided the successful bid, demonstrating to the relevant bodies, including England Hockey, that Martin Audio’s CDD series was best fit for purpose. Using patented Coaxial Differential Dispersion technology and featuring user rotatable horns, the powerful, passive two-way CDD15-WR provides 100° x 60° dispersion. Additional seating for the World Cup, doubling the capacity, will be accompanied by 17-metre high scaffolding, with the bottom tier seating fivemetre above the pitch. The sound system will adapt to the different World Cup and European Cup scenarios before settling in as a stand-alone system. There are also numerous hospitality boxes positioned in the North stand for the World Cup - all receiving OBA installed feeds.

In the first phase, the West, East and South stands only have been equipped with a total of 18 CDD15-WR 15-inch loudspeakers, which have been customised and weatherised to IP65. This includes seven CCD15-WR on the West stand, mounted on 4.6-metres custom designed poles in landscape mode. A further five are situated on the South terraces, with another four under the existing cantilevered stand, which contains the press area. The final pair feed the seats to each side of this stand. However, the present complement of 18 CDD15-WR will eventually rise to 23 as Neil explained. “For the World Cup, the North segment will be occupied by portakabins for corporate hospitality, and a broadcast centre. This will make way for the final five enclosures to be installed post World Cup on custom poles in the North stand.” He added: “These loudspeakers meet all the power and dispersion requirements, and exceed the IP rating of any competitor. The client is extremely happy. “We have been able to run the CDD15 without sub extension as they contain extended low end. Every single speaker has its own amplifier and DSP channel.” Completing the contract, OBA has supplied a 32-channel Soundcraft Si1 and custom designed software run through a Symetrix Radius DSP with its own PC, enabling it to be zoned from a touch screen. “We’ve also organised the radio system so it can be used in every seat without drop out, and supplied tie-lines over the console’s digital matrix for broadcast purposes,” said Neil. martin-audio.com

CLAIR BROTHERS BANKERS LIFE FIELDHOUSE To capitalise on the buzz of the Bankers Life Fieldhouse, the Indiana Pacers organisation turned to Randy Skaggs at Village Audio for innovative ideas on a high-energy system with low visual impact. They wanted complete courtside coverage on all sides and down-firing court coverage, with self-powered loudspeakers. Randy looked immediately to the Clair Brothers kiT Series for a solution. The kiTCurve, with its 90° H x 15° V coverage pattern, performed solidly for the short throw to the long sides of the court, but Randy recognised that something more directional was needed to project to the far court corners; and for that he sought a TrueFit - another breakthrough Clair Brothers concept. Clair Brothers and Village Audio collaborated to study the speaker positions and coverage angle requirements. They determined that indeed a custom dispersion on the scoreboard corners could offer better coverage with minimum overlap to other sources. A separate zone was created to cover the court itself and consists of the point source 12-inch member of the Clair Brothers kiT Series - the kiT12. Randy concluded: “IThe fact that Clair Brothers can deliver customised solutions is an undeniable asset. The team at Bankers Life Fieldhouse is thrilled with the result, as are we.” www.clairbrothers.com

DANLEY SOUND LABS DOAK CAMPBELL STADIUM The Florida State Seminoles play all of their home games at Doak Campbell Stadium, which has grown from 15,000 seats in 1953 to nearly 80,000 seats today. Now, the the Florida State University has the most powerful sound reinforcement system of any sports stadium in the world. The system is the first to feature two massive Danley J-5 Caleb loudspeakers, which have proven capable of delivering 113dB of clean, undistorted audio to the seating beyond the opposite end zone, along with additional Danley’s Jericho Horns, Synergy Horns, and BC subwoofers. Larry Lucas, Director of Audio & Broadcast Engineering at Anthony James Partners, created the new design for the system, which relies entirely on Danley’s point-source boxes. “Unlike most stadiums of its size, Doak Campbell Stadium has no balcony from which to hang a distributed system, or even to hang fill loudspeakers,” said Kyle VanLandingham, Project Manager for All Pro Sound, the company that installed the system. “The relatively small footprint of the Danley loudspeaker system allowed us to utilise spaces within the scoreboard structure instead of creating new spaces in various areas around the stadium. Aside from the increased simplicity of installation, the Danley Caleb and Jericho series loudspeakers provided the absolute best solution for clear, impactful coverage

across an incredibly large space.” Michael Walden, Systems Designer at All Pro Sound, worked with Larry’s plans to make the design a reality. Among those boxes are two Danley J-5 Caleb Horns, which provide coverage for the field and the far side of the stadium. At 10ft tall - and strategically packed with 108 drivers - the Caleb Horn fires phase-coherent audio with a 40° by 15° beam width and frequency response down to 30Hz. Doak Campbell Stadium is acutally the first facility to use more than one Caleb Horn. In addition, five Danley J-3 Jericho Horns cover the remainder of the stadium, with fill provided by four Danley SH-46 Synergy Horn loudspeakers and two Danley OS-80 molded loudspeakers. Eight Danley BC-218 subwoofers provide abundant low end. “It’s notable that this design ultimately required so few boxes,” said Michael. “In part, because of that simplicity, the end result is very balanced, very even, and very clean.” Kyle added: “From what I understand, FSU now has the most powerful sound reinforcement system in all of sports. At four channels each, 16 Danley DNA-20K4 PRO amplifiers power the system. You’re not going to go to a sporting event anywhere else and get a better experience. This system is at the top.” www.danleysoundlabs.com
