Channel Strips
The eight channel strips are virtually identical to each other, with
the only difference being that channels 1 – 4 are mono and
channels 5 – 8 are stereo. Each channel strip contains the following
components.
Level Control
The level control knob controls how much of the signal from the
mic or line inputs is sent to the channel. To adjust the level, simply
turn the knob to the desired level. In the leftmost position, levels
are cut completely, and in the rightmost position you get an
additional 10dB of gain.
PAN or BAL
This control—labeled PAN on the mono channels and BAL on
the stereo channels—lets you assign the channel to a particular
spot within the stereo spectrum. If you turn this knob to the left,
you can hear the signal move to the left, and if you turn it to the
right…you get the picture. The pan controls do this by adjusting
the amount of the signal being sent to the left main mix bus versus
the right main mix bus. The balance controls do it by controlling
the relative balance of the left and right channel signals being sent
to the left and right main mix buses.
PEAK LED
This indicator lets you know when the channel’s signal is clipping.
This light plays an important role in setting channel levels by
helping you know when to reduce the channel’s gain.
Aux
Here you’ll find knobs that control the levels of aux sends A and
B. AUX A is pre-fader, which means that the AUX A send is
affected only by the EQ and HPF settings. A pre-fader send is
usually used for cue sends (for example, sending a signal to
headphones while recording, for which you may not want the fader
to alter the channel’s level).
AUX B is post-fader, which means that the AUX B send is
affected by the fader (or level control knob in this instance), EQ
and HPF settings. A post-fader send is generally used for sending
the signal to an external effects device (so that the fader controls
the signal level). Like AUX A, AUX B can be used for routing
signals to external devices. And when you are using the onboard
effects processor, AUX B is used to control the level of the
channel’s signal being routed to the processor.

EQ
The MultiMix gives you three bands of EQ per channel. Using
these knobs, you can tailor the channel’s signal by boosting some
frequencies and cutting others. The LO and HI controls are
shelving controls with fixed frequencies of 75 Hz and 12 kHz
respectively. The MID control has a peaking response fixed at 2.5
kHz.
“Shelving” means that the mixer boosts or cuts all frequencies past
the specified frequency. “Peaking” means that frequencies above
and below the specified frequency fall off, forming a peak in a
graphical representation.
Master Section
The Master Section is the heart of the mixer, where the channel
inputs and aux returns all are mixed together and routed in various
ways.
Main Mix
The signals from all channels and aux sends are sent to the main
mix. The MAIN MIX level control is the one you’ll use to control
the overall level of those combined signals. This knob affects the
levels of the signals sent to the MAIN MIX OUT and the 2-
TRACK OUT. In its leftmost position the signal is cut off
completely, and in the rightmost position you get an additional
10dB of gain.
2TK To Mix
When you press this switch, the signal coming in through the 2-
TRACK IN gets routed to the MAIN MIX, joining whichever
other signals are already part of the main mix. Used this way, the
2-TRACK IN effectively becomes another stereo channel (but
without all the extras like pan, EQ, etc.).
HDPH / CTRL RM
The HDPH / CTRL RM knob controls the level of the signal
being sent to the CTRL RM OUT and the PHONES output. The
level of this signal is represented by the LED meters. The “CTRL
RM” in the name of this knob refers to the fact that it controls the
signal that typically is sent to the control room monitors of a
studio, where someone—usually an engineer—is working the
mixer. However, don’t be intimidated if you’re using this mixer in
your bedroom, which probably isn’t equipped with a control room.
In this scenario, you can use headphones or connect the CTRL
RM OUT to your speakers.
