AUX Send Features
Six auxiliary Sends are available for creating individual output mixes. These can be used to drive
effects processors, provide monitor mixes, create broadcast or alternate sound reinforcement
mixes, or for other special requirements.
NOTE: Normally, the signal feeding the Aux Sends is derived after the chan fader (Post-Fader).
The fader controls the level of the chan signal feeding the individual Aux Send pots. Each Aux
Send pot is then used to generate a sub-mix of this channel signal. This Post-fader signal feeding
the Auxes is also affected by the Mute switch; if the channel is muted, the Aux Send no longer
receives a signal. There are many cases where an independent mix is desired, and the operator
doesn’t want the Chan fader to affect the signal. The 3 PRE switches allow the operator to change
the source to each pair of Auxes from the normal post-fader signal to a signal unaffected by the
fader. The default PRE setting is pre-fader, but it is still post-insert/post-EQ/post-Mute. An internal
setting (per channel) can be changed so that this PRE source becomes either pre-insert or pre-
EQ. An additional jumper allows this PRE setting to also be independent of the channel mute.
Aux 1 - 2 PRE
AUX 1/2 stereo pair is post-fader
AUX 1/2 stereo pair is pre-fader
Aux Sends 1 & 2
Auxes 1 and 2 are permanently configured as a stereo pair. The upper knob controls the level
and the lower knob is the PAN control. This stereo aux send can be used for any type of stereo
feed from the console, such as live two-track recording, stereo in-ear monitors, alternate stereo
feed for broadcast and stereo signal processors. By properly using the pan control Auxes 1 and 2
can also be used as discrete mono Aux buses.

Aux Sends 3, 4, 5 & 6
Auxes 3, 4, 5, & 6 are configured as discrete mono aux sends. They are typically used to feed signal
processors and for on-stage monitors.
AUX 3-4 PRE
AUX 3 and AUX 4 are post-fader
AUX 3 and AUX 4 are pre-fader
Auxes 3, 4, 5, & 6 Level Controls the send level to Auxes 3, 4, 5, & 6.
AUX 5-6 PRE
AUX 5 and AUX 6 are post fader.
AUX 5 and AUX 6 are pre-fader.
