Main inputs
The Main Inputs are stereo (TRS) or mono (TS) input jacks that accept line or headphone level
signals. The Main Inputs are the audio source for all of the outputs that do NOT have audio
connected to the Aux Input jacks. Use the Left (stereo) input if you have a stereo TRS cable.
Use both the Left and Right input if you have mono (TS) cables for each input. If you plug a
cable into the Right (mono) input jack only, the signal on the tip of the connector will be the
source for both left and right audio.
Since this audio is used if no other audio is inserted into an Aux input or Listen input, the Main
audio will be monitored when using the listen function.
Aux inputs
The Aux inputs are stereo (TRS) input jacks that accept line or headphone level signals. Using
the Aux input on a channel will override using the Main input audio for its' output. This audio will
be directly passed on to the listen buss if the listen function is active.
Listen Input
The Listen input is stereo (TRS) and accepts line or headphone level signals. Using the Listen
Input will override using the Main input audio for the listen output. This audio will be directly
passed on to the listen buss at all times. This audio is muted if the Talk All button or the
Talkback Footswitch input is active.
Listen output
The Listen output jack can drive headphones as well as line level inputs. The Listen control on
the front of the unit controls the volume of all of the audio present on this output.
This output contains either the Main input audio or the Listen input signal if this jack is used. It
also carries the audio present on Aux inputs with a lit Listen LED. If the Talkback Footswitch or
the Talk All switches are active, only talkback audio is present.
