UTILITY OUT EFX SEND RING (COLD) TIP (HOT) SLEEVE (SHIELD) TRS BALANCED WIRING TIP (HOT) SLEEVE (SHIELD) TS UNBALANCED WIRING 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 control, 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 amplifiers, 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. The signal at these TRS outputs is postfader 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 STEREO EFX RETURN To create a stage monitor mix, with levels set independently from the main mix, patch these TRS jacks into your monitor amplifier inputs. These jacks can also be used to feed the inputs of an effects device. See AUX and PRE FADER for more information. 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.
