CHANNEL STRIPS
The six vertical channel strips contain all the individual
controls for each channel. Each channel strip works
independently of each other, and adjusts only the signal
plugged into the jacks below it.
Note: If the optional wireless modules are installed, CH
1-4 control strips can adjust the signal from the wireless
microphones as well.
1. LEVEL
– These controls adjust the amount of gain
for each channel available to the MAIN output. Adjust
these controls to achieve a good mix between connected
microphones/instruments. These controls do not adjust the
amount of gain available for the MONITOR output.
2. MON
– These controls adjust the amount of gain for
each channel available to the MONITOR output. Since the
monitor output will typically be used for onstage reference,
set the individual levels to achieve a perfect monitoring mix.
These controls do not adjust the amount of gain available for
the MAIN output.
3. DSP/REV AUX
– These controls adjust the amount of
3. DSP/REV AUX – These controls adjust the amount of 3. DSP/REV AUX
DSP effects applied individually to channels 1-8. This allows
you to set more DSP effects to the microphone channels,
and less to channels with instruments connected. These
controls only adjust the amount of DSP applied to each
channel; to set the individual parameters of the DSP effects,
refer to the DSP REV CONTROL panel control.
A secondary function of this control is to adjust the
presence of that channel’s signal in the ¼” AUX output mix.
As the control is turned clockwise, the signal is increased.
As the control is turned counter-clockwise, the signal is
decreased.
4. HIGH
– These controls adjust the amount of high
frequency in the audio signal for each channel. Increase the
HIGH control to add sparkle to vocals and instruments, but
keep in mind that excessive high frequency equalization can
lead to feedback. Decrease the HIGH control to reduce vocal
sibilance, reduce tape hiss, or “bacon crackle” from vinyl
recordings.
5. MED
– These controls adjust the amount of midrange
frequency in the audio signal for each channel. Midrange is
the most commonly adjusted range in audio. Pianos, guitars
and the human voice can be dramatically adjusted sonically
by adjusting the midrange. For vocals a slight boost in the
midrange provides a good sound when playing through well-
balanced set of speakers.
6. LOW
– These controls adjust the amount of low
frequency in the audio signal for each channel. Low
frequency adjustments are made to add serious thump
to kick drums, fatten up bass lines, or add a “full” sound
to instruments and vocalists. You can also decrease low
frequency to save your speakers from blowing during
playback of audio with a heavy bass presence.
7. SOURCE SELECT
– These buttons toggle the source
input for channels 1-4. If using an optional UHF wireless
expansion module, select UHF. If you are connecting a
microphone or line instrument to the front panel via the ¼”
or XLR jacks, set the switch to WIRE.
8. MIC PAD 30dB
– These switches can provide a 30dB
signal cut for high level input sources. The MIC PAD is
designed to prevent overloading a channel with a high-level
signal. If the switch is set incorrectly, excessively distorted
audio can result. If you are connecting a line-level input
source, such as a line out from a mixing device, set the
switch to ON. If you are connecting a microphone-level
signal, set the switch to OFF.
