Send signal from Inputs to the Main Output
Prior to sending signal anywhere, preamp gain or trim should be set correctly for
the input source. Follow the How to Use Gain Assistant section for best results.
This ensures optimum signal level coming into the channel for processing, but more
importantly when thinking about sending (routing) signals, changing the preamp
gain or trim also affects the level of signal being sent to any outputs.
Send one input at a time using the PROCESSING screen
1.
Go to PROCESSING / INPUTS and select the channel
to be sent to the Main LR output.
2.
Use the fader on the right-hand side to adjust the
send level for just the selected channel. Touch/Click
and drag, or select the fader and use the Touchscreen
rotary control (CQ-12T, CQ-18T).
 Repeat steps 1 and 2 for other inputs as required.
3.
Adjust the (overall) Main LR output level by going to
the OUTPUTS tab, selecting the Main LR output
channel, and again using the fader on the right-hand
side.
