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.
