Polk Audio PSW650 instruction manual Option #1

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.

FIGURE 4.

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.

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.
