MULTI-CHANNEL ANALOG MIXERS WITH ENHANCED FX, USB RECORDING MODES, AND BLUETOOTH®
25
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 left and right inputs of your main power amplifiers, powered speak-
ers, or serial effects 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 1 = 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 1/4" connectors driven by balanced
or unbalanced sources.
To connect balanced lines to these outputs, use a 1/4" Tip-Ring-Sleeve (TRS) plug. “TRS” stands for Tip-Ring-Sleeve,
the three connection points available on a stereo 1/4" or balanced phone jack or plug. TRS jacks and plugs are used
for balanced signals and are wired as follows:
1/4" TRS Balanced Mono Wiring:
Sleeve = Shield
Tip = Hot (+)
Ring = Cold (–)
To connect unbalanced lines to these outputs, use a 1/4" mono (TS) phone plug, wired as follows:
1/4" 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.
