If you are using a re-
ceiver 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 
amplifi 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 nifi   cant fraction 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 fi  er and pream pli fi  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 speaker-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.
