4) If your receiver/ampli-
fier has preamp output
jacks and main input
jacks for the left, center
and right channels, or
left and right channels
only, 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-D112 and PSW-D115
incorporate a variable high-
pass crossover in addition to
a variable low-pass crossover.
When hooked up as shown
above, the subwoofer will
limit the low-frequency infor-
mation 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.
