MC960 Power Amp Installation  

Run the MS7XSC cable 
from the dmc1H or 
dmc1HC wall housing to 
the remote power 
amplifier.  
Run the MS3XSC cable from the 

remote amplifier to 
each volume 
control (use the SVC96 for stereo or the MVC1 for mono). 
From each volume control, run the MS2SXSC to each 
respective speaker as shown in Figure 17.  
The remote power amplifier should be located in a closet or 
utility closet and should be located within 6 feet of a 
standard NEMA 5-15R 120VAC receptacle. Install a 1-gang 

and a 2-gang box 
at the location for 
the remote 
amplifier on a 

stud. Allocate the 1-gang and 2-
gang boxes relative to one another 
as shown in Figure 18. Run all 
MS3XSC cables from the volume 
controls to the remote amplifier’s 
2-gang box.  
Run the MS7XSC cable from the 
dmc3-4 to the remote amplifier’s 1-gang 
box. The remote amplifier is designed to 
mount over the 1-gang and 2-gang boxes on a single stud. Note: The 
speaker cables CANNOT be located in the same gang box used for 
120VAC wiring. 
Each pair of stereo or mono music speakers is controlled by a single 
volume control. The volume controls install in a standard single gang box. 
Run a MS3XSC cable from each volume control location to the remote
