Top Panel Controls Mono Input Channel Section The following section details four mono input channels. 1. 2. MIC Inputs - Use these balanced XLR inputs to connect low Impedance microphones and low level signals from direct boxes. The MIC inputs feature +48V phantom power, allowing you to use condenser microphones.
7 Top Panel Controls 8. 9. MON Auxiliary Control - 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. 8 9 10 FX Auxiliary Control - FX Auxiliary Control - The channel’s FX knob controls the amount of signal that is sent to the effects bus.
Top Panel Controls Stereo Input Channel Section The following section details four stereo input channels. 14. MIC Inputs (CH5/6 & CH7/8) - Use these balanced XLR inputs to connect low Impedance microphones and low level signals from direct boxes. The MIC inputs feature +48V phantom power, allowing you to use condenser microphones. XLR Connector pin-out - Pin 1: Ground, Pin 2: Hot (+), Pin 3: Cold (-) 14 15 15. Stereo ¼” Input Jacks - Use the ¼” jacks for connecting stereo line level sources.
18 Top Panel Controls 20. 21. 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. 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. 22.
