A Tour of the MultiMix

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.
