1. Press the Esc button to clear all pending changes and reset the LCD.

2. Press and hold the Audio button for 3 seconds, until it flashes red. The View, Esc, and one input button lights red.

NThe input button that lights is the last input button pressed in the previous front panel operation made prior to this viewing.

The LCD shows the input audio level (gain) delay for the indicated (lit) input, and the output audio volume for any outputs tied to that lit input.

3. Select the desired input button, and observe the LCD screen.

4. Using the left encoder ([) on the front panel, increase or decrease the input audio level (gain) in 1 dB steps, until the desired setting is reached

(see figure 3-26). The range is -18 dB to +24 dB.

Step 4.

Rotate this encoder to increase or decrease the input audio level (gain) by 1 dB steps.
