31. MAIN MIX FADER control
The MAIN MIX FADER controls the output level just before the MAIN MIX outputs and the 2TRK outputs. When the
fader is fully down the MAIN MIX is off , the "0" marking indicates a +4dBu nominal output level. Typically this fader is
set near the "0" label and le alone, but it can be used for song fadeouts or quick system-wide mutes.
32. C.ROOM L & R jack outputs
These JACK connectors provide an unbalanced line-level signal that can be used to monitor the MAIN MIX program or
as an addi onal output.
33. PHONES stereo jack output
STEREO JACK connector for the headphones output: only stereo headphones with a minimum impedance of 32 Ohms
should be connected to this output.
34. C.ROOM/PHONES LEVEL control
This controls the CONTROL ROOM and PHONES output's level.
NOTE: The signal at these outputs is the same.
35. AUX 1 jack output (Mi12 only)
This jack connector sends out unbalanced line-level signals made of the sum of the input channels' AUX 1 sends, usually
for connec ng to the inputs of an external eff ect devices or stage monitor amplifi ers. This signal is pre-fader, meaning
that it doesn't depend on the posi on of the channel's FADER.
36. AUX 1 (Mi10) / AUX2 (Mi12) jack output
This jack connector sends out unbalanced line-level signals made of the sum of the input channels' AUX 1 (Mi10) or
AUX 2 (Mi12) sends, usually for connec ng to the inputs of an external eff ect devices or stage monitor amplifi ers. This
signal is post-fader, or in other words it depends on the posi on of the channel's FADER.
37. L & R LEVEL METERS
The level meters are made of two columns of of four LEDs with three colours to indicate diff erent ranges of signal
level:
• green = shows the normal opera ve level of the signal (from -20 to 0 dBpeak)
• yellow = shows the nominal opera ve level of the signal (from 0 to +6 dBpeak)
• red = shows a high signal level (near +20 dBpeak CLIP level).
38. +48V phantom switch
This switch ac vates (LED on) and deac vates (LED Off ) the phantom power on MIC Inputs. Most professional condenser
microphones require phantom power, which is a lower DC voltage delivered to the microphone on pin 2 and 3 of the
XLR microphone connector. Dynamic microphones do not require phantom power, however phantom power will not
harm most dynamic microphones should you plug one in while the phantom power is on. Check the manual of your
microphone to fi nd out for sure whether or not phantom power can damage it.
39. ON led
Indicates when the mixer is switched on.
40. 18V~ socket
Here’s where you plug in your mixer’s external power supply. You should always connect your power supply to the mixer
before you plug the power supply into an electrical outlet.
41. POWER switch
Switch this one on and your mixer has power. Switch it off and it doesn’t. Make sure that all master output knobs are
turned all the way down when powering your mixer up or down.
42. PRODUCT LABEL
In this label are wri en the most important informa on about the mixer, model, line voltage, consump on, serial
number.
