2) If your receiver/amplifier has subwoofer outputs or
preamp output jacks for the left and right channels. See
Figure 2.
Note: Some receivers/amplifiers have a single (mono)
subwoofer output. In this case, it is recommended that you
use a "Y"-connector (not included) to maximize the
subwoofer's performance.

3) If your receiver/amplifier has preamp output jacks and
main input jacks for the left and right channels or you have a
separate pre-amp/ processor and power amplifier. See
Figure 3.
RIGHT
This method of hookup can offer the highest level of
performance for your complete loudspeaker system. The
LEFT
PSW-D110/DPS-10 incorporates 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 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
LEFT
high frequencies with greater clarity
