USB2.0 inputs and outputs
Channels sent from the MultiMix to the
computer
The USB2.0 port sends every individual mixer channel as well as
the MultiMix’s MAIN OUT/2-TRACK OUT left and right signals
to the computer. This means that, for the MultiMix 16 USB2.0, 16
individual channels are sent to the computer along with the MAIN
stereo pair (18 channels in total.)
Individual channels
The INDIVIDUAL channels sent to the computer send the signal
after the preamp gain knob, the high-pass filter, the three-band EQ,
and the channel fader.
The effects of the AUX send knobs are NOT included in the
outputs of the individual channels.
MAIN MIX channels
The MAIN mix channels sent to the computer exactly mirror the
MAIN output of the mixer. If you are only interested in making
stereo recordings, consider recording the MAIN channels in your
recording software.
Channels returned from the computer to the
MultiMix
The USB2.0 port receives a stereo audio stream from the
computer and assigns it to the 2-TRACK IN left and right
channels of your MultiMix mixer. Note that, if a device is
connected to the MultiMix’s 2-TRACK IN inputs, the signal from
this device is merged with the signal from the computer.
To understand why the AUX
signals are not blended into
the individual channel feeds
to the computer, consider the
nature of AUX sends:
Every channel can send none,
some, or all of its signal to
the AUX processors. For
instance, in the MultiMix 12,
12 different signals could be
sent to an external processor,
all at different levels.
However, that AUX
processor can only return at
most a stereo pair into the
mixer. There’s no way that
the processor could route the
effects of each channel back
to that channel directly
without including the signal
from the other channels as
well.
