SAS20

EMBEDDED AUDIO PROCESSING

Audio for Video

Features The SAS20 is a SD-SDI embedded 8-channel audio shuffler. The SAS20 accepts an incoming SDI stream with embedded audio, de-embeds the audio and relocates (shuffles) and combines the audio channels with 4 channels that can be sourced by an ADD-ON card as the ADC20/24 and DIO24. Each local audio channel can be selected as one out of 16. The local channels can be individual processed before mixing and swapping. The control items are gain, phase and delay.

The ADD-ON channels can be processed before mixing on the ADD-ON card.

Free selection of all 16 channels + 4 ADD-ON channels and re-insert these channels in a free selectable group.

Individual local audio gain (0.25dB steps) and phase (0-180 deg) per channel Full 8 channel mixing and swapping into one group (4 channels) Delay 2600ms max for each local channel.

Audio peak detection Peak reference 0, -6,-12, -18dBFS EDH processing and generation Full control and status monitoring through the front panel of the SFR04/SFR08/SFR18 frame and the Ethernet port (ACP) Optional 1 fiber input (replacing 1 SDI input) or 1 fiber output (replacing 1 SDI output) on I/O panel Optional 1 CVBS output (replacing 1 SDI output) on I/O panel

Complementary cards: ADC20, ADC24, ADL24, DIO24, DIO48, DLA44, DLA43

Applications

Correction of embedded audio channels by combining local and external audio channels
