Embedded Audio Assignment

The audio signals are passed back and forth between the 1RU Audio Breakout Unit and the switcher as embedded audio signals in the SDI loop between the components.

The MADI interface supports an SFP transceiver module using the AES10-1991, AES10-2003, and AES10-2008 specifications for a maximum of 56 or 64 audio channels, depending on the specification.

The embedded audio signals sent to the ABU outputs are fully assignable.

Note: All embedded audio streams going to the 1RU Audio Breakout Unit pass through the hardware and are available on the SDI1 OUT.

MADI Outputs

Audio channels to the MADI SFP are fixed to specific audio sources from the switcher.
