Basic Operation
The following section explains the basic setup and operation of the MixPad
MXP124 and MXP124FX.
1. Before connecting any microphones
or instruments, make sure that the
power of all your systems components
including the MixPad mixer is turned
off. Make sure that the MAIN MIX and
MIX 2/PHONES controls are turned all
the way down.
2. Connect the cables from your
microphones and instruments to
the mixer. Microphones should be
connected to the XLR inputs of
channels 1-4. Line level devices can
be plugged into the mono ¼” input
channels (1-4) or the stacked-stereo
input channels (5-12). Acoustic
instruments and electric guitars and
basses need to be connected to a direct
box or preamp before plugging into the
mixer.
3. Switch on the power of any peripheral devices, and then power up the
MixPad mixer.
NOTE: It is important to remember the Golden Rule of audio… “LAST ON,
FIRST OFF.” Translated, this means that when turning on your system, you
should always turn your power amplifiers or powered monitors on LAST, and
when turning your system off, turn your power amps off FIRST. This helps
avoid any loud pops caused by rush current at power up, or down, which
can sometimes damage loudspeakers.
4. Turn on your power amp or powered monitors and raise the level control to
the manufacturers recommended operating level.
5. Set the input gain of each input channel so that the PEAK indicators only
light occasionally during the loudest input each channel will see.
6. Set the MAIN MIX fader to the “0” position.
7. While speaking into the microphones (at performance level) or playing an
instrument, slowly raise the input channel volume faders until the desired
level is reached.
8. If you wish to adjust the tone of each channel, adjust the equalizer controls
as desired. You may have to re-adjust the channel volume.
7
Adding Digital Effects (MXP124FX Only)
The MXP124FX features built-in, high quality, 24-bit Multi Effect Processors,
offering 100 studio grade effects presets. The DIGITAL EFFECTS section
features clean Delays, lush Reverbs and multi-effects like Delay + Reverb. The
following details the operation of the internal DSP effects in the DIGITAL
EFFECTS section.
1. Connect a mic or instrument to the desired channel, adjust
the level and equalizer to your liking and make sure the
MAIN MIX fader level is set so you can hear it in your
speakers.
2. Press the effects ON button to activate the digital effects
channel strip.
3. Select the desired effects program using the SELECT control
knob located in the middle of the channel strip. Rotate
the SELECT switch to one of the 100 effects and press to
confirm the selection.
4. Set the effects to MAIN MIX control to the 12 o’clock
position.
5. Use the FX control on the input channel to adjust the level
of signal to sent to the effects. If the Peak indicator flashes
red, the signal is overloading the DSP, lower the channel FX
controls until the indicator no longer lights red.
Note: The signal feeding the FX control is sent after the
channel Fader, so the channel Fader has an effect on that
level, meaning the FX level tracks up and down with the
channel Fader.
8
USB Connectivity (MXP124FX Only)
The MXP124FX has a built-in stereo USB audio interface allowing you to record
and playback from a computer using virtually any digital recording software.
Setting up your mixer with a computer is a simple procedure that takes just
a few minutes. The following section describes how to connect and setup the
MXP124FX with a computer.
1. Connect the MXP124FX to the
computer using a standard USB
cable (not included).
2. In your audio software, set the
input and output device to the
MXP124FX.
3. The audio sent from the
MXP124FX to the computer
follows the Main Mix bus.
4. For playback, you can return the
USB stereo signal directly into the
main left and right mix bus so that
the playback from the PC sums
with the MAIN mix on the console. To hear the USB playback in the MAIN
MIX press the TAPE/USB TO MAIN MIX switch.
5. The TAPE/USB TO MIX 2 + PHONES switch is used to assign the USB
return to the Mix 2 and headphones bus. This allows you to mix the
playback in studio monitors or isolate the playback to a mix zone.

Mono Input Channel Section
The following section details four mono input channels.
1.
MIC Inputs - Use these balanced XLR inputs to connect
low Impedance microphones and low level signals from
direct boxes. The MIC inputs feature +48V phantom
power, allowing you to use condenser microphones.
XLR Connector pin-out - Pin 1: Ground, Pin 2: Hot (+),
Pin 3: Cold (-)
2.
Line Level Input - Use these balanced TRS ¼” inputs
to connect synthesizers, drum machines, effects
processors or any line-level signal. You can connect
balanced and unbalanced devices to these inputs.
TRS phone jacks Connector pin-out - Sleeve: Ground,
Tip: Hot (+), Ring: Cold (-)
3.
GAIN Control - Variable GAIN control with a range of +5
to +45dB on the MIC input and -20 to +20dB on the
LINE input.
4.
HPF Switch - The high pass filter rolls off the low
frequencies from the XLR MIC inputs from 80Hz and
below at the rate of 12dB per octave. The high pass
filter allows you to remove the lower frequencies that
you don’t want the microphone to pick up. In live sound
applications, the high pass filter is useful for removing
stage rumble.
5.
6.
COMP Control (CH1 & CH2) - The COMP knob adjusts
the level of compression applied to the channel. As the
COMP knob is turned clockwise, the compression ratio
is raised and the output gain is adjusted accordingly.
The dynamic range of the channel is narrowed, where
softer signals will be magnified and loud signals will be
subdued to sit better in the mix.
Too much compression can create a pumping effect,
eliminate all dynamic range, and lead to feedback.
Equalizer (HIGH, MID, and LOW) - This three-band
equalizer allows you to contour a channel’s high, mid,
and low frequency bands. When the control is set to the
12 o’clock (detent) position, there is no effect on the
signal. Turning the controls fully clockwise will raise the
level of the frequency band +15 dB, while turning the
controls fully counterclockwise will lower the level of the
frequency band -15 dB.

device connected to the FX SEND jack located on the front panel jack
field.
MON Auxiliary Control (MXP124) - Controls the amount of that channel’s
signal that is sent to the MON Output. The signal feeding MON is sent
before, or pre, the channel fader, so the channel fader has no effect on
the MON level. The MON is usually used to create a separate mix for a
floor monitor system.
8.
PAN Control - The PAN control is used to place or position the mono signal
into the stereo main left and right mix bus. You can create a stereo image
by panning some input signals to the left and others to the right.
9.
PEAK Indicator - This LED indicator will flash red when the channel input
signal peaks. To reduce distortion, turn the GAIN control counterclockwise
until the clip indicator does not light during normal use.

5. To adjust the angle of the
mixer, loosen the wing-nut (C), rotate
the mixer to the desired angle then retighten the wing-nut.
Note: Take care when placing the
mixer on a stand, to ensure that it is
on a level, steady surface and will not
tip over. Arrange the cables parallel
to the microphone stand with enough
slack so the cables are not pulling the
mixer.
