UTILITY OUT
The stereo signal at these TRS jacks is the same as at the MAIN OUT 
, but with one important difference:
After the MAIN MIX Fader 
, the mix is sent through the UTILITY OUT LEVEL 
con- trol, allowing you to set levels as desired without disturbing the main mix level.
SUB OUT
In live sound applications, these TRS jacks can be patched into one or two stereo amplifi- ers, thereby allowing you to control levels independently via the SUB Faders 
.
Alternatively, use the MAIN OUT 
to feed the amplifiers and one stereo SUB OUT 
pair to feed a recorder.
In studio applications, these outputs can be used as four separate paths to feed four tracks of a multitrack recorder.
See ASSIGN 
and SUB ASSIGN 
for more information.
EFX SEND
The signal at these TRS outputs is post- fader only, so they cannot be used as traditional stage monitor cues. They’re intended to patch into effects device inputs; hence the name “EFX.” See EFX 1 (EXT) 
and EFX 2 (INT) 
for more information.
Note: The EFX 2 signal path also feeds the CFX Mixer’s internal EMAC EFFECTS PROCESSOR 
inputs. If you’re using EMAC and just one outboard processor, patch that processor via EFX SEND 1 for independent control of the effects send level.
We recommend going into a stereo reverb in mono and returning in stereo. We have found that on most “stereo” reverbs the second input just ties up an extra EFX send and adds nothing to the sound. There are exceptions, so feel free to try it both ways. If your effects device is true stereo all the way through, use EFX SEND 1 to feed its left input and EFX SEND 2 to feed the right input.
AUX SEND
To create a stage monitor mix, with levels set independently from the main mix, patch these TRS jacks into your monitor amplifier in- puts. These jacks can also be used to feed the inputs of an effects device.
See AUX 
and PRE FADER 
for more information.
STEREO EFX RETURN
Patch the outputs of external parallel effects devices to these inputs.
Note: The EFX 2 return signal is combined with the signal from the CFX Mixer’s internal EMAC EFFECTS PROCESSOR 
. If you’re using EMAC and just one outboard processor, patch the outboard processor via EFX 1 RETURN for independent control of the effects return level.
When connecting a mono device (just one cord), always use the LEFT (MONO) input and plug nothing into the RIGHT input. A trick called “jack normalling” will cause the signal to appear on both sides.
