Sometimes, with very low listening levels, your subwoofer might not 
get enough of a bass signal  from your AVR to ―trip‖ the Auto-On 
circuit.  Should you ever find this to be the case you may leave this 
switch to ―On‖, or turn up the AVR’s subwoofer level some (be sure 
to recalibrate channels levels with your sound meter afterwards).  
 

Crossover Feature Switches.  

If you allow your DD/DTS surround-

sound receiver or processor to manage bass frequencies (again, 
highly recommended), this switch should be set to ―

Disabled

‖, elimi-

nating the effects of the  ―Crossover Frequency‖ knob and allowing 
your sub to reproduce just what is fed from the receiver.  If you use 
the sub in a two channel (stereo only) configuration, then ―Enable‖ 
the crossover and adjust the knob to best blend the sub into the out-
put of your speakers.   
 
 

 

Power

.  This heavy-duty two-position switch next to the power cord 

will completely cut the power to your sub amp.  Flip this switch to off  
before you ever move the sub or change inputs or outputs.  Do not 
plug this sub into receiver convenience power outlets.   Allow five  
minutes of ―off‖ time before switching back ―on‖. 
 

Fuse

.  User replaceable, contact your dealer if you have trouble find-

ing one.  The fuse can be accessed by a small door  immediately 
next to the power cord fitting  
(where you should also find a spare one for your use). 
 

Read ahead for advanced features including Room Compensa-
tion, and Parametric Equalization (PEQ).
