2.3.2 Audio Connections
The digital audio inputs and reference input are provided on female BNC connectors.
Input signals should be compliant with AES3-id-1995 (unbalanced, 75Ω, 1V peak-to-
peak standard output). AES3-id signals are very similar to analog composite video,
although dedicated AES3 distribution equipment should be used. If the loop-through
BNC connectors are not being used to feed additional equipment, terminate them with
a standard 75Ω video terminator.
The digital audio output is provided on a female BNC connector. The output is 75Ω,
unbalanced, with signal levels compliant with AES3-id-1995.
