Balanced Audio (AVP/CAB/BAL)
With this option four balanced analogue audio channels can be connected to the
Audio/Data D-Type connector on a VCM option card.
An XLR socket is provided for each of the four analogue inputs, and a 75 Ω BNC
plug for an AES3 reference signal. The reference signal contains a 1 kHz tone at -
6 dBFS at a sample rate of 48 kHz.
