Amplified 
In-Wall 
Volume Control
Unique in-wall 
volume control 
fits amazingly  
in a single gang 
electrical box,  
yet houses a 
powerful 50W RMS 
amplifier. It is perfect for simple self  contained audio in 
a single room, expanding a system to add another zone, 
or adding to an existing system to play a local source. 
Highly efficient Class D amplifier accepts standard line 
level input, and provides 25W RMS x 2CH, with full 
20Hz ~ 20KHz response. Separately available DC power 
supply allows power to be applied from a remote 
location, increasing installation flexibility. Rotary 
encoder provides noise free control and five segment 
LED display indicates ON/OFF status and volume 
setting. Power and speaker connections are stripped 
tinned leads, L:/R inputs are RCA female.
