Each audio input gain and attenuation indicator indicates a range of 6 dB when lit. (Output

1 LED off = 0 dB to 5 dB, Output 1 lit = 6 dB to 11 dB, Output 1 and 2 lit = 12 dB to 17 dB, Output 1 through 3 lit = 18 dB.) The level indicators are secondary functions of the Output 1 through Output 3 LEDs.

Operation
