The M1 Multimedia amplifier can be equipped with wall mounted control panels on each zone 
output. A zone output can be controlled by more then one wall mounted control panel. The 
maximum number of wall mounted control panels connected to the M1 multimedia amplifier is 4.  
These wall mounted control panels are controlled by an RS485 data bus and must be connected 
with the M1 with “twisted pair” or “CAT5” cable. 
Following settings can be changed: 
- Volume of the zone output  which the panel is configured for (e.g. Zone 1) 
- Input source selection. (e.g. CD player, Tuner, Microphone…) 
The wall mounted control panel can be configured to control the settings of a zone output (e.g. 
Living room, Board room …). This is done by jumper settings on the inside of the wall mounted 
control panel.  
If the wall mounted control panel is connected to the M1, and the M1 is turned on, the digit on 
the wall mounted control panel will show a zero for a couple of seconds, for the next couple of 
seconds it will show the zone output for which the wall mounted control panel is configured and 
last it will keep displaying the selected input source. 
When changing the volume of the zone output, the digit on the wall mounted control panel will 
show the zone outputs volume. The volume will be changed in smaller steps then the digit can 
show. If one of the volume control buttons is held down, the volume will keep increasing or 
decreasing. After the change has been made, the digit will show again the selected input source.
