If you are using a receiver 

which does not have a sub-
 woof er output or line level 
outputs (pre-outs), you can 
connect its speak er outputs 
to the subwoofer’s speaker-
level inputs. The front speak ers 
can still be con nect ed to your 
receiver.

The subwoofer’s internal 

ampliÞ er supplies the power to 
reproduce the low fre quen cy 
range. It receives a sample of 
the signal going to your front 
speakers. (An in sig niÞ   cant frac-
tion of your receiver’s power is 
trans ferred to the subwoofer).

There is no 

need to use the 
speaker level 
inputs if you are 
using a sep a rate 
am pli Þ  er and pre-
am pli Þ  er. Such 
systems are 
best con nect ed 
using the line level 
inputs as shown in the pre vi ous 
diagrams.

If you are using the line 

level inputs and there is a 
excessive amount of noise 
or hum present, using the 
speak er level inputs may yield a 
lower background noise level.

Your receiver MUST have com mon 
grounded outputs, or it will be dam-
 aged if con nect ed to the sub woof -
er’s speaker level inputs.
