The GAIN knob controls the analog amplifier that adjusts the input sensitivity 

of the mic or line input signal. The gain range of the mic input is 0–60 dB; the 

line’s range is -20 to +40 dB. A unity gain indication for the line input appears 

at the 10:00 position (unity gain for the mic input is fully counterclockwise). 

Dual-concentric labels surround the knob indicating the appropriate levels 

(mic outside, line inside).

The green SIG LED lights when the selected mic/line signal exceeds -15 dBu. 

The red OL LED lights when the signal is 3 dB below clipping the ADC. The 

SIG and OL LEDs remain lit only while the signal level is above their corre-

sponding thresholds.

The V-Pot displays and controls one of the following functions at a time: pan, 

HPF, Aux send levels, Aux pan (for linked Aux sends), digital trim, and channel 

metering. The function is assigned from the V-POT CONTROL area. 

The V-Pot has 15 LEDs in a ring from 7:00 to 5:00. They light clockwise as the 

signal level increases unless otherwise noted. The V-Pot also has a bottom red 

LED used to indicate different functions including meter clip, default settings, 

on/off, etc. The 12:00 LED is also sometimes used to indicate a nominal setting 

(i.e., pan set to center). Each function’s specific behavior is discussed in
