JBL PSW-D115 Speaker User Manual

4) If your receiver/ampli-
fier has preamp output
jacks and main input
jacks for the left, center
and right channels, or
you have a separate
preamp/processor and
power amplifier.
This method of hookup can
offer the highest level of
performance for your
complete loudspeaker system.
The PSW-D115 incorporates a
variable high-pass crossover
in addition to a variable low-
pass crossover. When hooked
up as shown, the subwoofer
will limit the low-frequency
information that is returned
to your receiver/amplifier.
Your receiver/amplifier does
not need to waste valuable
power reproducing the low
frequencies. In addition,
since no
low-frequency
information is being sent
to your main loudspeakers,
they are able to reproduce
mid and high frequencies
with greater clarity.
