Select the input source
1. Select the input source with the capacitive touch button labelled “Select”:
The input source selection LED indicates the input source or off.
NOTICE: The source (microphone inputs or line inputs), ID and zone selection are
pre‑defined at configuration. Refer to Wall Control Panel DIP switch settings, page 24.
Adjust the audio output volume level
1. Press the capacitive touch buttons up or down arrows to adjust audio level:
One touch per 3 dB step.
2. The volume control LED indicates the audio output volume level:
The maximum level indicated is dependent upon the predefined maximum allowable
level that is set in the PC GUI (DSP setup output level).
Notice!
Use slow deliberate touches to the capacitive touch areas on products. Excessively fast
tapping may not be recognized by the unit.
Notice!
The level will increase or decrease 3dB for every button press of the arrows, and the LED is
6dB per step. Therefore it will sometimes require 2 pushes to see the next LED illuminate.
