A switch labeled +48V is located next to each gain knob. This switch may be engaged to provide phantom power for condensor mics and any other device which may require phantom power by way of the XLR input. This power is supplied at a constant rate to allow use of all eight inputs simultaneously, without any degradation of audio quality. Pin 1 = GND, Pin 2 = +48V, Pin 3 = +48V

Gain Control

This knob provides 44dB of gain to the processed signal. The amplifier has inherent gain of 10dB thus delivering a total gain possibility of 54dB.

-20dB Pad

A -20dB pad is available on each channel of the DigiMAX LT for reducing incoming signal levels. Using this pad can provide a more manageable signal from high output devices giving the operator greater control over the incoming signal and a much reduced chance of over-driving the input, thereby avoiding distortion.

The pad is available only for the XLR input on each channel. The pad does not work for the line level inputs.

Channel LEDs

The three LEDs found on each channel are provided to serve different functions:

-20dBu- The LED farthest to the left is labeled -20 and serves to monitor whether or not signal is present at the channel output.

-10dBu- The LED in the middle is labeled -10 and indicates a signal level of -10dBU
