Extron electronic DMP 64 manual Mic/Line Input Signal Controls, Gain Control GAIN

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 and off. Phantom power is typically used to power a condenser microphone.

The Mute button, accessible in the dialog box, silences the input.

The Polarity button, accessible in the dialog box, allows the polarity of the wires connected to the audio connectors (+/tip and –/ring) to be flipped to correct for miswired connectors.
