Mic/Line Input Signal Controls

The input signal processor chain allows adjustments to program or microphone audio
material before input to the main mixer.

Gain Control (GAIN)

The gain control provides a single long-throw fader with a range of –18 dB to +80 dB,
adjustable in 1 dB increments with the fader, or in 0.1 dB increments using direct entry
in the input signal level readout below the fader. The
peak reading meter holds the peak level for one second,
displaying it numerically in the box below the meter. The
default setting is unity gain (0.0 dB).
The Phantom Power checkbox, accessible in the
dialog box, toggles the +48 VDC phantom power on

condenser microphone.
