Digital Audio Specification
Audio Input
The digital input of the VCM accepts four stereo pairs of digital audio. The available encoding options depend upon the licenses
enabled.
The HD/SD-SDI input of the VCM's can be used for audio input, where eight stereo pairs can be extracted from four groups of
embedded audio. The DID associated with each group is set when the unit leaves the factory:
