four remote locations. The appearance of the wall panel
is matched to the Bosch loudspeaker volume controls.
The zone can be activated or deactivated, and the music
source can be easily changed. The status of each zone
and music source is indicated by an LED.
A standard CAT 5 cable is used to connect the wall
panel to the mixer-amplifier. The maximum distance is

information.
