Controlling Volume
The LEVEL on the mixer is ALWAYS operational, regardless whether the Source Selector function is
active or not. This remote control is ATTENUATE ONLY.
To set the volume control of the remote control, you can follow these steps:
1. Turn the remote control LEVEL to maximum (full clockwise).
2. Set the volume control on the mixer to the loudest you will ever need the system to be.
3. Turn the remote control LEVEL knob down to a comfortable or typical operating level. Now the
volume control on the remote control cannot turn the volume up above what is set on the mixer.
