CONTROL MODULE INSTALLATION:
• The input receptacle of each emitter has a symbol showing an
input arrow into a circle:
• The output receptacle of each emitter has a symbol showing an
output arrow out of the circle:
To ensure that subsequent emitters operate properly, IT IS ESSENTIAL TO CONNECT THE OUTPUT
OF A
CONTROL MODULE OR EMITTER TO THE INPUT
OF THE NEXT EMITTER. This is not a safety issue.
4. Remove the plastic tab from the battery housing of the remote control.
5. Aim the infrared remote control at the front of the control module and cycle through all 8 volume
settings, plus OFF. (See Volume Settings at the end of this document or online at
www.cambridgesoundmanagement.com.) Verify that a “whooshing” or air conditioning-like sound is
emitted by each of the four test speakers. Keep volume at the highest level during installation –
Volume Step 8. This will help to quickly identify any emitter problems.

1. Select a location for the control unit within 16 feet of the first emitter
location (Fig. 1). Typically, control modules are housed in a storage
closet or other out-of-the-way location. If mounting multiple control
modules near one another, it is recommended to leave 1 foot of
space between each (Fig. 2). Otherwise the remote control may
inadvertently change volume settings on all control modules.
2. Mount the control module on the wall near a convenient AC power
outlet. Figure 3 shows a typical wall elevation with possible control
module locations. Route an initial 16-foot (or longer) cable from the
ceiling location where the first emitter is to be installed to the location
where the control module will be permanently installed. If a longer
cable is needed, it must conform to Cambridge Sound
Management’s custom cabling specifications detailed at the end of
this document.
• The cable can be dressed where it will be visible using a plastic,
self-sticking wire channel such as those manufactured by
Wiremold (www.wiremold.com), or by pulling the cable down in
the wall cavity to a hole drilled in the wall. The hole may be
covered by the control module.
3. Plug the power supply into the wall and into the back of the control
module.
• Do a trial assembly with 4 emitters and the control module. Insert one
end of a 16-foot cable into one of the two RJ-45 output receptacles on
the back of the control module. Insert the other end of the cable into
the input
receptacle on the top of an emitter. Repeat for each of the
other 3 emitters.
