Volume controller for adding the signal from channel 21/22 and 23/24 to external effects devices (Effect Send,
switch N° 69 POST), or for controlling active stage monitors (Monitor Send, switch N° 69 PRE) Use the line
outputs AUX SEND and 2 control (N 12) for control.
69 AUX 1 + AUX 2 PRE/POST CHANNEL 21/22 AND 23/24
When using AUX 1 or AUX 2 to control an external effects device, bring the switch to the down position POST.
The control signal is now picked up after the channel volume controller (N 74), it is therefore dependent on
the latter. To control a stage monitor, bring the switch to the up position PRE. The signal is picked up before
the channel volume controller (N 74) and the volume of the stage monitor can be adjusted independently of
the channel volume.
