If you are using a
receiver which does not
have a subwoofer output or
line level outputs (pre-
outs), you can connect its
speaker outputs to the
subwoofer’s Speaker-Level
inputs. The front speakers
can still be connected to
your receiver.
The subwoofer’s internal
amplifier supplies the
power to reproduce the low
frequency range. It
receives a sample of the
signal going to your front
speakers. (An insignificant
fraction of your receiver’s
power is transferred to the
subwoofer).
There is no need to use
the Speaker Level inputs if
you are using a separate
amplifier and preamplifier.
Such systems are best
connected using the Line
Level inputs as shown in
the previous 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
common grounded outputs, or it
will be damaged if connected to
the subwoofer’s Speaker Level
inputs.
