Polk Audio PSW 650 - Manual (Page 7)

The “high pass crossover” switch
(Figure 5) on the PSW650 gives you
the option of filtering bass from your
main front speakers for the purpose
of increasing power handling and
lowering distortion at high volume
levels. If you are using small front
main speakers, select “80Hz.” For
large floor-standing speakers, especially
those with built-in powered woofers,
select “full range.” This function works
only when the subwoofer is connected
to the amplifier via speaker wire. OPTION #2
This option is recommended for
surround systems with pre-amp
output jacks, particularly “high end”
separates systems.
Connect your main front speakers to
your receiver or amplifier in the normal
way. If your pre-amp, processor, ampli-
fier or receiver has a spare set of front
left and right pre-outputs, connect them
to the Line Level In jacks of the sub-
woofer (Figure 6). Use well-shielded
RCA type cables. If your pre-amp,
processor, amplifier or receiver has a
single set of pre-outputs and they are
being used to deliver signal to an ampli-
fier, use “Y” cables as shown in Figure 6.

HOOK-UP OPTIONS (CONTINUED)
OPTION #1
This is the recommended hook-up option
for most stereo and Dolby
® Pro Logic ®
systems, particularly those receivers
that do not have pre-amp output jacks.
In this method, the subwoofer is fed
signal by the speaker level outputs of
your amp or receiver. This method is
very easy to connect, is less susceptible
to hum and noise, and provides high
performance sound. With this method
there is absolutely no reason to connect
the PSW650 to the subwoofer output
jack of Dolby Pro Logic electronics.
Connect speaker wires from your amp
or receiver to the PSW650’s speaker
input connectors, and connect your
main left and right front speakers to the
speaker output jacks (Figure 4). Be
sure to maintain correct polarity as
described in the general hook up
instructions.
If you have a Dolby ® Digital surround
decoder, use the “Large” setting for
the front left and right speakers in the
“speaker set up” or “bass management”
function of your electronics. Select the
subwoofer as “Off” or “None.” This will
direct all bass and LFE (low frequency
effects) channel information to the
subwoofer via the left and right speaker
outputs. Consult the owner’s manual of
your electronics to learn how to select
these settings.
