INSTALLATION (continued): 

 
Cutout dimensions are 6.0

H x 9.875

W.  We recommend allowing a minimum 

mounting depth of 3.5

 
Electrical connections to the subwoofer amplifier consist of the AC mains input, 
audio input (either low or high level), and speaker output. 
 
CAUTION 

 

Damage not covered by the warranty can occur if the AC SELECT switch 

setting does not match the actual AC input voltage.  Also, the AC input fuse must be 
sized per the fuse recommendations printed on the faceplate. 
 
The amplifier is designed to operate on either 115VAC/60Hz or 230VAC/50-60Hz AC 
input.  The amplifier is shipped in the North American configuration (AC input switch 
setting and AC fuse selection are set for 120VAC/60Hz).     
 
To change the AC input range, start by disconnecting AC power from the amplifier.  
DO NOT CHANGE AC INPUT RANGE WITH THE AC POWER CONNECTED TO THE 
AMPLIFIER!  Set the AC Select switch to the desired range (115VAC or 230VAC).  ALSO, 
THE AC INPUT FUSE MUST BE PROPERLY SELECTED TO MATCH THE AC INPUT RANGE!  
Please refer to the faceplate silkscreen for the correct fuse size and rating.  The 
fuseholder is integrated into the AC inlet connector housing and is located just 
below the AC inlet connector. 
 
AC mains connections are simply made with the provided AC cable.  One end of the 
provided cable (IEC320 style receptacle) plugs into the connector located on the 
amplifier faceplate 

 the other end, into a 15A or 20A three-pronged North American 

AC receptacle.  Due to the wide variety of plugs outside of North America, we are 
unable to stock and offer power cables suitable for other regions. 
 
Should the AC inlet fuse blow, REMOVE AC POWER FROM THE UNIT; then, determine 
and clear the source of the problem (such as shorted speaker output).  With AC 
power removed, replace the blown fuse.  THE AC INPUT FUSE MUST BE PROPERLY 
SELECTED TO MATCH THE AC INPUT RANGE!  Please refer to the faceplate silkscreen 
for the correct fuse size and rating.  Replacing the fuse with a value other than that 
shown on the faceplate silkscreen will void the warranty.
