24. EFX Control
This control alters the signal level that is sent to the
EFX send (AUX 3) output and the built-in digital
effect processor. The EFX send signal can be used
in conjunction with external signal processors (this
signal of which can be returned to mixer via the AUX
return input), or simply as an additional auxiliary
output.
25. Pan / Balance Controls
This alternates the degree or level of audio that the
left and right side of the main mix should receive. On
Mic channels, the PAN control will adjust the level
that the left and right should receive (pan), where as
on a stereo channel, adjusting the BAL control will
attenuate the left or right audio signals accordingly
(balance).
26. O n B u t t o n a n d
Indicator
This turns the channel
on, allowing the user to
use the feed from the
channel's inputs to supply
the MAIN L/R, GROUP 1/2,
AUX and EFX buses. The
corresponding indicator
will be illuminated when
turned on.
27. 1-2 and L/R Buttons
These handy buttons allow you to decide the audio
path of the corresponding channel. Pushing the "1-
2" button allows the signal to be sent to the Group
1-2 mix, where the "L/R" allows it to be sent to the
Main L/R mix.
28. Peak Indicator
This LED indicator will illuminate when the channel
hits high peaks, 6 dB before overload occurs. It is
best to adjust the channel level control to a level
slightly prior to the peak indicator does not light up.
This will ensure a greater dynamic range of audio.
This indicator also doubles as a Solo indicator, when
the SOLO button is engaged.
29. Solo Button
The Solo button is pushed to allow the signal of a
corresponding channel to be sent to the Control
Room / Phones control. The signal is either that of a
pre- or post-fader depending on the pre/post button
in the master section.

30. Level Faders
These faders allow users to adjust the level of the
signal from the corresponding input channel that is
to be sent to the destinations selected by the 1-2
and L/R buttons.
Digital Effect Processor
31. Program Control
This rotary control allows users to select the digital
effect program of your choice. There are 16 points
on the rotary control, each of which corresponds with
an effect type. See the digital effect table for more
information.
32. Parameter Control
Turning this control will adjust the one main parameter
of the selected effect. Each effect's parameter can
be found on the digital effect table.
33. Effect On Button
This button is pushed to turn the corresponding effect
panel on or off. Effects can also be disabled by using
a footswitch with the jack on the rear of the mixer.
Please note: this button will not lock down as similar
buttons on the mixer do.

Master Section
34. AUX Return Controls
These controls adjust the signal level of audio fed
through to the stereo AUX Return inputs. The "To AUX
1" control adjusts the pre-fader level of the signal from
the AUX Return inputs to the AUX 1 mixing buses.
35. EFX Return (AUX Return 2) Control
This control adjusts the signal level of audio fed
through to stereo AUX Return 2 inputs. If no device
is plugged into the AUX Return 2 inputs, this control
then acts as the final level control of the built-in Digital
Effect Engine.
