Polk Audio 650 instruction manual HOW to Tell if Your Subwoofer Output Jack is Filtered or not

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.
