Infrared (IR) Emitter Port [8]
This jack is provided for infrared control of the source component. It is a routed output that will only emit
commands from a Volume Control Module in a zone that has selected that source. Some components
have a 2-cond. IR input jack on the back. It is recommended that this direct connection be used.
CAUTION: Do not confuse a serial data port connection with an infrared port.
12v DC Trigger [12]
- This is a 12v DC output that turns on when that source is selected. The output
can be used to trigger a relay for power control of the source component.
CAUTION: Do not hook up devices to the Trigger that will exceed 50mA of current draw.
Audio Input [13]
- For connection to source component
Loop Out [14]
- To loop the same audio component source into a home theater receiver or an amplifier
