AUX
This control sends a signal to an auxiliary bus. The signal is sourced pre-
fade or post-fade depending on the PRE switch position and is a com-
bined sum of the left and right stereo signals. The pre-fade source selec-
tion will be affected by the channel ON/OFF switch if active. The send
control varies the signal level to the bus from off (fully attenuated) to
+6dB, with unity gain at the arrow.
