Main Mix Fader Control; Main Mix L & R Xlr Output (Balanced); Main Mix L & R Jack Output (Balanced); Phones Stereo Jack Output - PROEL MQ10FX User Manual

26. MAIN MIX FADER control

The MAIN MIX controls the output level just before the MAIN MIX outputs and HEADPHONE output. When
the potentiometer is fully down the MAIN MIX is off, while the "0" indicates a +4dBu nominal output level.
Typically, this control is set near the "0" label and left alone, but it can be used for song fadeouts or quick
system-wide mutes.
27. MAIN MIX L & R XLR output (balanced)
These XLR and provide a balanced line-level signal that represents the fully mixed stereo signal controlled by
the MAIN MIX. Connect these to the inputs of your power amplifier, powered speaker or other audio
processors.
NOTE: whenever possible, use always balanced cables. Unbalanced lines may also be used but they may
result in noise over long cable runs. In any case, avoid using a balanced cable for one channel and an
unbalanced one for the other.
28. MAIN MIX L & R jack output (balanced)
These jack connectors are connected in parallel to the respective XLR outputs.

29. 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. The signal is the same of MAIN MIX outputs.

30. C.ROOM jack output

These JACK connectors provide an unbalanced line-level signal that can be used to monitor the MAIN MIX
program or as an additional output.

31. PHONES and C.ROOM level control

This controls the PHONES and C.ROOM output's level.
32. L & R LEVEL meters
The level meters are made of two columns of four LEDs with three colors to indicate different ranges of signal
level:
• green = shows the normal operative level of the signal (from -30 to -6 dBpeak)
• yellow = shows the nominal operative level of the signal (from 0 to +6 dBpeak)
• red = shows a high signal level (near +20 dBpeak CLIP level).
33. +48V phantom switch and LED
This switch activates (LED on) and deactivates (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 find out for sure whether or not phantom
power can damage it.

34. ON LED

Indicates when the mixer is switched on.
