Main Mix - Mackie Onyx 1220i Quick Start Manual

Main 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, or serial effects processor (or a 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.

MAIN MIX and FIREWIRE
The main mix can be sent to your computer via two
dedicated Firewire signals. The output is not affected by
the main mix fader, allowing you to record the main mix
of live performances. The left main mix will appear on
FireWire output channel 15, and the right on
channel 16.
In addition to recording the main mix using FireWire,
you can record individual channels using FireWire, for
studio mixing at a later date. See page 15.
TAPE OUT
This RCA unbalanced output is a copy of the main mix
(post fader). You can use it to record the main mix on
an analog tape deck for example.
