Polk Audio PSW650 instruction manual HOW to Tell if Your Subwoofer Output Jack is Filtered or not

If you have a Dolby® Digital surround processor, 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 sub- woofer via the left and right pre-amp outputs. Consult the owner’s manual of your electronics to learn how to select these settings.

CONNECTING LFE

WITH OPTION #1 AND #2

When using either hook-up OPTION #1 or #2 with a Dolby Digital system, you may also connect the subwoofer output to the PSW650. In Dolby Digital systems, select the subwoofer as “On” or “Yes” in the “speaker set up” or “bass manage- ment” function of your electronics. Consult the owner’s manual of your electronics to learn how to select these

OPTION #3

This option uses the subwoofer output jack as the only source of signal to the PSW650. In most cases we do not recommend using only this subwoofer output jack to connect the subwoofer. Why? Because many receivers and pre- amp/processors, the subwoofer output jack is filtered; that is, all sounds above a certain frequency (usually 80Hz) have been filtered out. That defeats the sub’s variable crossover control, one of your primary tools in adjusting the subwoofer to blend perfectly with your main speak- ers. Some units have unfiltered sub- woofer outputs, and fewer still allow you to switch the filter off. Read your receiver or preamp/processor’s manual to find out which is the case with your equipment. If you still don’t know, try the experiment described on page 9.

If the subwoofer output jack is filtered, we suggest using hook up OPTION #1 or #2. If it is unfiltered, connect the subwoofer output jack to either of the line level “IN” jacks (Figure 8). With Dolby Digital systems, select subwoofer as “on” or “yes” in the “speaker set up” or “bass management” function of your electronics. Read the owner’s manual of your electronics to learn how to select this setting.

HOW TO TELL IF YOUR SUBWOOFER OUTPUT JACK IS FILTERED OR NOT

Use the “speaker set-up” or “bass man- agement” function of your Dolby Digital processor to select subwoofer as “on” or “yes.” Connect the subwoofer output jack to the “LFE/Subwoofer” input of the PSW650. Disconnect the other speakers in the system so that all you can hear is the subwoofer. Play music or a movie with vocal content. If you can hear and understand the words, your output jack is not filtered. If all you can hear is bass, and the vocals are barely or not at all audible, your subwoofer input jack is filtered.

YOUR SUBWOOFER OUTPUT JACK IS FILTERED OR NOT” on the next

page. If your sub output is filtered, connect it to the “LFE/Subwoofer” input of the PSW650. If the subwoofer output is unfiltered, connect to either of the “IN” line input jacks (Figure 7).
