Main/Subs Mix - Mackie Onyx 1640i Quick Start Manual

Main/Subs Mix

XLR MAIN OUTPUTS
The male XLR output connectors provide a balanced
line-level signal that represents the end of the mixer
chain, where your fully mixed stereo main mix signals
enter the real world. Connect these outputs to the
inputs of your main power amplifi ers, powered speakers,
serial effects processor, graphic equalizer, or
compressor/limiter. The output provides a fully balanced
signal playing the same program material as the 1/4"
TRS main outs.
MAIN OUTPUT LEVEL (+4 dB/MIC)
When this recessed switch is out (+4 dB), the XLR
main outputs provide a "+4 dBu" line-level signal. You
can then connect these outputs to the line-level inputs
of power amplifi ers, powered loudspeakers, or serial
processors. In a studio setting, you could connect the
main mix to the inputs of a professional stereo recorder.
When the switch is pushed in (mic), the XLR main
outputs are attenuated to microphone level. You can
then connect these outputs safely to the microphone
inputs of another mixer, providing a submix for
keyboards or drums, for example, in a live sound
application. The main outputs can then be plugged
directly into a stage snake, and appear back at the front
of house console like any other microphone level source.
When mic is engaged, you can safely plug the XLR
main output into another mixer's microphone input,
even if it provides 48 V phantom power.
The switch is recessed to reduce the chance of
accidently turning it on or off when plugging things in.
1/4" TRS MAIN OUTPUTS
These 1/4" TRS output connectors provide the
balanced or unbalanced line-level output of the
main mix. This is the same signal that appears at
the XLR main outputs, except it is not affected by
the main output level switch.
MAIN MIX FADER
This is the main stereo fader that adjusts the level
of the XLR and 1/4" main outputs, and the tape
output. It does not affect the FireWire output of the
main mix.
If the gain of each channel has been set up
correctly for all your microphones, line-level
sources, guitars, and so on, then these channels can
be added to the main mix by careful adjustment of the
channel faders. The main mix fader is then used to turn
the complete main mix level up and down.

SUB ASSIGN switches
Subgroups are typically used as master faders for a
group of channels on their way to the main mix. Let us
assume you have a drum kit hogging up seven channels
and you are going to want to fade them out at a different
rate than the other channels. You do not want to try that
with seven hands or seven fi ngers, so just
un-assign these channels from the main mix, reassign
them to subgroups 1-2, engage the assign to main mix
left on subgroup 1 and assign to main mix right on
subgroup 2. Now you can ride the entire drum mix with
two faders: subgroups 1 and 2
If you engage just one assign to main mix button per
subgroup (left or right), the signal sent to the main mix
will be the same level as the sub outs. If you want the
subgroup to appear in the center of the main mix,
engage both the assign to main mix left and right
buttons. The signal will be sent to both sides.
