Stereo input channels have a “SEND” and “RETURN”
break-jack
facility. This is to
allow the channel signal to be sent out to, and returned from an external audio-pro-
cessing unit. The channel signals are always present at the “SEND” jack, but when
‘insert’ is not selected, the channel signals will by-pass the “RETURN” jack.
Press the “INS” button to ‘open’ the “RETURN” jack and receive the modified signal
from the external audio-processing unit.

This function ‘isolates’ the module switch data from the computer. There are many
instances during a production rehearsal, when module routing or level changes need
to be made to solve a problem.
When you are rehearsing a sequence of cues, there may not be time to record the
changes in all of the cues that are affected. When you press the ‘ISOLATE’ button,
previously recorded switch data will be ignored by the module, leaving the switches
at their new setting until you cancel the function.

Press this button to mute the channel manually.
The MUTE switch has a secondary function when used in conjunction with the
CHECK switch, (located on the OSC Module). If a channel is muted (MUTE switch
‘On’) and the CHECK switch is pressed, the muted channel is unmuted, but all other
channels are forced into MUTE. This allows the originally muted channel(s) to have a
‘SOLO’ function.
