Decrease the audio
attenuation (thereby
increasing the audio level)
that is applied to the
output volume level by
1 dB per button push.
The input buttons display the selected output's audio volume level.
Each lit input button beyond input 1 indicates that 3 percent of the total
input volume is applied to the output.
In this example, the green input buttons display 61 percent of the
applied audio input.
The unlit input buttons indicate an audio volume attenuation of 26 dB.
