The INPUT SELECT button will switch between input 1, RCA analog audio
input, and input 2, 3.5 mm TRS input.
The LEVEL SELECT button will switch between MIC, LINE, BASS, and TREBLE
levels.
When MIC or LINE are selected, the Down, Up, and Mute buttons will adjust
the volume or mute the selected input.
When BASS or TREBLE are selected, the Down and Up buttons will adjust
the bass or treble levels of the analog audio input signal.
Audio ducking is enabled by default. This can be disabled via RS232.
The line level ducking amount may be increased or decreased via RS232. The
default value is 10 steps below the current value.
For example, if the line audio level is at 35, it will drop to 25 while the
microphone is being used. The line level audio will ramp up to the original
value after five seconds of no audio signal being detected on the microphone
input.
