Connecting the Audio Input Cables
An encoder may have up to five audio input cards (AICs), each of which has two analog and
two stereo digital audio ports.
To connect the audio cables:
Connect one of the following audio sources:
Analog.
If you have an analog audio source, connect the audio cable with the Phoenix
1881367 connector
to the analog audio port, and connect the other end to the audio
source device. On the encoder, the analog ports are labeled “ANLG AUD1” and
“ANLG AUD2.”
Install the cable shield drain lug under the head of the AIC panel fastener screw.
For cable building information, refer to the pinout information in
Digital.
If you have a digital audio source, connect a coaxial cable with the BNC
connector from the digital audio port to the audio source. On the encoders, the
digital audio ports are labeled “DGTL AUD1” and “DGTL AUD2.”
