76. TALKBACK MIC IN
This is where you plug in your external talkback
microphone. This female XLR connector does not have
phantom power, so use a dynamic microphone or a self-
powered condenser microphone.
77. TALKBACK LINE OUT
This 1/4" TRS output connector provides a balanced or
unbalanced line-level signal for connecting to the input
of an external intercom system or other line-level device.
78. MONO OUT
This male XLR output connector provides a balanced
line-level signal that is a combination of the left and right
MAIN OUT signals (L+R). You can use this for a separate
mix that doesn’t require a stereo feed, or to simply test
the monaural compatibility of your stereo mix.
79. LEFT/RIGHT MAIN OUTS
There are two sets of outputs for the Left/Right Main
Outputs: Male XLR connectors that provide balanced
line-level signals and 1/4" TRS connectors that provide
balanced or unbalanced line-level signals. Each XLR
connector is in parallel with its corresponding 1/4" TRS
connector, and carries exactly the same signal.
This represents the end of the mixer chain, where
your fully mixed stereo signal enters the real world.
Connect these to the inputs of your main power ampli-
fiers, powered speakers, or serial effects processor (like
a graphic equalizer or compressor/limiter).

80. MAIN INSERT
These 1/4" TRS jacks are for connecting serial effects
such as compressors, equalizers, deessers, or filters. The
insert point is after the mix amps, but before the MAIN
MIX faders. Refer to the description of the channel
insert on page 21 to see how to make this connection.
81. MONITOR OUT
These 1/4" TRS jacks provide a balanced line-level signal
that can be used to provide another main mix output (with
MAIN MIX TO MON/PHONES selected in the PHONES/
MONITOR Section), or to monitor soloed channels.
Connect these outputs to the inputs of an amplifier,
powered speaker, headphone distribution amplifier, or
recording device.
8. MATRIX OUT
These 1/4" TRS jacks provide balanced line-level sig-
nals for the MATRIX A and B mixes. These can be con-
nected to the inputs of an amplifier, powered speaker,
headphone distribution amplifier, or recording device.
8. REDUNDANT POWER SUPPLY Connector
This is where you connect the optional Onyx PS
External Redundant Power Supply. Normally, the Onyx
80 Series operates on its built-in universal power sup-
ply. With the Onyx PS connected, in the unlikely event
that the internal power supply should fail, the external
supply will seamlessly take over powering the Onyx 80
Series mixing console.
This provides an extra measure of insurance that the
show will go on.
