Polk DS7200SW DB25-DB25 Input Cable Delima

Help! I have a question regarding my Polk DS7200SW
powered subwoofer and Polk Audio RM Digital Solution DS-1 A/V Preamp
Processor Loudspeaker Receiver. These came with satellite speakers as a
home theater (HT) system as the Polk 700DS7200 I believe.

These two components connect via a 13' 25-pin DB cord that Polk included in
the package. Well that cable went missing after moving to a new city. Is
there a special non-standard cable that Polk made because the aftermarket
one I thought would work isn't after replacing it?

I've purchased a Planet Waves 5ft Core Cable Cable Snake DB25-DB25 screwed
it securely in connecting a audio signal to both units, even reversed the direction of cable, but the DS7200SW powered subwoofer light remains red when powered on, not green
when connected.

I tried resetting the receiver to its default mode, checked the fuse on the
subwoofer, wiggled the connecting input cable, but no luck. Here is a link to the system owner's manual:


Polk customer service said "Unfortunately the DB25 cable has not been available in years.
I would suggest posting this on our Forum"
. So here I am.

Anyway you can help me out here? I'd love to be able to use this equipment
again but this snag is preventing me from doing so.

    The DB25 was a standard low capacitance DB25 type cable. I'm not familiar with the cable you bought, but it sounds like it should work. Normally I would suggest reversing the cable, but it sounds as though you've already done that. The only thing I can think of to do is to spray some good quality electrical contact cleaner in the connecting sockets of both the preamp and power amp and make sure the connectors are not going into the sockets at an angle when putting them in.
    Maybe check the continuity of the cable with a VOM?

    I tried all of the above and the Planet Waves snake cable was the culprit. Luckily a eBay seller listed the correct Polk Audio RM Digital Solution DS-1 Interface cable (Item# 201541248106) and gave my HTR gear LIFE AGAIN! :#

    Thank you for your reply, Ken.

    Great, I'm glad it's working correctly now.

  • Hey, what is the model number on that subwoofer? I need one and don't have the model number to search

    The sub doesn't have its own model number it was part of the RMDS1 and the followup RMDS7200 system. Which system do you have? I might be able to help.
