L/R Main Output Jacks
The main outputs provide a line-level signal that represents the end of the mixer chain, where the fully mixed stereo
signal enters the real world. Connect these to the lef and right inputs of your main power amplifiers, powered speak-
ers, or serial eects processor (like a graphic equalizer or compressor/limiter).
The male XLR connectors provide a balanced line-level signal and is wired as follows, according to standards speci
-
fied by the AES (Audio Engineering Society):
XLR Balanced Wiring:
Pin  = Shield (ground)
Pin 2 = Positive (+ or hot)
Pin 3 = Negative (– or cold)
In addition to accepting balanced XLR connectors, the main outputs may also accept /4" connectors driven by balanced
or unbalanced sources.
To connect balanced lines to these outputs, use a /4" Tip-Ring-Sleeve (TRS) plug. “TRS” stands for Tip-Ring-Sleeve,
the three connection points available on a stereo /4" or balanced phone jack or plug. TRS jacks and plugs are used
for balanced signals and are wired as follows:
/4" TRS Balanced Mono Wiring:
Sleeve = Shield
Tip = Hot (+)
Ring = Cold (–)
To connect unbalanced lines to these outputs, use a /4" mono (TS) phone plug, wired as follows:
/4" TS Unbalanced Mono Wiring:
Sleeve = Shield
Tip = Hot (+)
The XLR outputs are 6 dB hotter than the TRS outputs. When the meters read “0”, the TRS outputs are at 0 dBu.
