VP/CAB/BAL
This enables four balanced AES3 audio channels to be connected to the Audio/Data D-Type connector on a VCM option card.
An XLR socket is provided for each of the four digital inputs, and a 75 Ω BNC plug provides an AES3 reference signal at 3.072 Mbps.
The reference signal contains a 1 kHz tone at -6 dBFS at a sample rate of 48 kHz.
The cable connections are as follows:
