The Volume Increment, Volume Decrement, and Mute discrete provides audio volume control of the
audio output. (Note: The volume and mute controls have no affect on the Line Out output volume.)
There are six discrete inputs for audio suppression. There are three active low and three active high
inputs. The Audio Suppression inputs suppress the Audio Out output by activating any one of multiple
inputs. The threshold voltages are as follows:
Active HIGH discrete inputs: Input will go active with input voltages above 8.5V
Active LOW discrete inputs: Input will go active with input voltages below 5.0V

The Line Out output is always at a fixed output. The Line Out is not affected by the volume controls,
mute function, and suppression inputs.
