Alternate output selector switches
These under-panel switches select the signal source for the Alt out-
put. They select between the L R pre-fade, L R post-fade or the
monitor L R signals.
Aux 1 & 2 master level controls
For adjusting the level of the Aux 1 and 2 outputs. The range of
level control is from off to +6dB.
Master L R faders
High quality 100mm faders for the main L R outputs. 10dB gain at
the top, unity gain marked at “0”.
Monitor selector switches
These 4 switches select the signal source for the headphones moni-
tor and the meters. They work on a priority basis. If they are all up
then the post-fade main L R signals will feed the monitor circuit, if
USB and 2 TRK are pressed, then only the 2 TRK signals will feed
the monitor circuit. The stereo option of pressing both AUX 1 and
AUX 2 together allows Aux 1 to feed the left and Aux 2 to feed the
right monitor circuit. This is useful if a stereo mix is set up using
Auxes 1 & 2.
