CHANNEL SECTION: CHANNELS 1-4 1. MIC INPUT: XLR balanced, low-impedance channel input optimized for a microphone or other low-level source. Pin 2 is the positive input. Because of the wide range of gain adjustment, signal levels as high as +10 dBV (2.45 V RMS) 9 can be accommodated. When the phantom power is enabled, this connector has +48 V on pins 2 and 3 with pin 1 as the ground reference. (The Mic Input can also be found on channels 5 through 8.) 8 2. HI-Z/LINE INPUT: 1/4" balanced TRS hig

This control sets the Main level going to the power amp when in Main/Monitor mode (see System Mode #24). A good starting position for this control is the center detent position (12:00). 27. PHANTOM POWER SWITCH: Applies 48 V DC voltage to all input XLR connectors to power micro- phones that require it. CAUTION! When phantom

30. LEFT/MONO OUTPUT: This 1/4" jack provides an output from the Left Main mix to supply external amp/speaker combinations. The level of this signal is determined by the Main Level control. When no plug is connected to the Right Output (#31) then the right signal is mixed with the left, and both can be accessed at the Left/Mono Output. This works well when you use the internal amps for monitor and external amps for Main. Only one patch cord is required to get the Main out to the external amp. 3
