Stereo Input Channel Section
The following section details four stacked stereo input channels.
11.Stereo ¼” Input Jacks - Use the ¼” jacks for connecting stereo 
line level sources. For stereo inputs use the LINE L to connect 
the left channel and the LINE R to connect the right channel. 11 
Use the LEFT input when connecting a mono input signal to
the Stereo Input channels. You can connect outputs from high impedance microphones, synthesizers and drum machines to these inputs. The LINE inputs have a nominal operating level

12.FX Auxiliary Control (MXP124FX) - FX Auxiliary Control - The channel’s FX knob controls the amount of signal that is sent to the effects bus. The signal of the FX bus in the MXP124FX is routed to the Digital Effects section for on- board signal processing. The FX signal can also be sent to an external effect device connected to the FX SEND jack located on the front panel jack field.

MON Auxiliary Control (MXP124) - Controls the amount of that channel’s signal that is sent to the MON Output. The signal feeding MON is sent before, or pre, the channel fader, so the channel fader has no effect on the MON level. The MON is usually used to create a separate mix for a floor monitor system.
13.BAL Control - This control is used to place, or position, the stereo signal into the main left and right stereo mix field. You can create a stereo image by panning some input signals to the left and others to the right.
14.PEAK Indicator - This LED indicator will flash RED when the channel input signal peaks. To reduce distortion, turn the LEVEL control counterclockwise or lower the volume of the input device until the clip indicator does not light during normal use.
15.LEVEL Control - This knob controls the volume of channel inputs and is used to continuously adjust the loudness of the various signals being blended together at the Main Outputs.
