Is there a chance this unit could reduce the humming in my Klipsch subwoofer caused when I hook RCA's from my wall port?

I not totally sure, but I know if there is humming you have some electrical interference. The cables are possibly too close to the conduit in the walls or some other issue. I've had no problems with my setup, but when I turn my microwave on the sub hums. Not a big deal for me since it's not used much. So it's worth a try, if not return it.

We purchase the unit and it did NOT work. End up disposing the wireless device.

Have you ruled out a ground loop as the source of hum? http://www.youtube.com/watch?v=4YM1iwC6vhg http://en.wikipedia.org/wiki/Ground_loop_%28electricity%29

Dear John--Perhaps I guessed wrong. If the sub-woofer hums when you touch the RCA plug on the end of the cable, it is indeed an amplified sub-woofer. I share your expectation that the sub-woofer should work when the RCA plug is plugged into the STR-DH800 subwoofer output. All I can think of is to double check the Speaker Pattern setting of the STR-DH800 as described on Pages 20 and 47 of the Operating Instructions--if the selection isn't X/X.1, the sub-woofer will not be enabled. Good luck!Bill

This type of device should not cause any noise in a sound system. Most of these devices provide some filtering so if anything the noise should be lower but these types of devices will not fix many issues with grounds on other pieces of equipment that are plugged into the rack power strip. I would look for a ground problem in your rack or sound system. Most of the time you have a cable that has gone bad. I will be putting two of these into a rack for a large PA and will write a review when I get them installed. Good luck.

It could be the settings in your receiver. If it's for a surround sound system there's a setting in most receivers that requires you to turn the subwoofer setting to "ON" in the Setup or Settings menu... I hope that works!

Mine is not comming from the sub. I've disconnected the sub and all the speakers 1 at a time and still have it. I did go into the Direct TV set-up and changed some audio settings and it is now at a lower voluume, but is still there. I thought maybe it was the Direct TV Receiver, but I disconnected it & still get have the hum running the receiver on fm stations.Thanks for the inputP.S. I have the Onkyo TX-SR705, not the 805.

I also agree with the checking the cables but here's another thing to look at. This kind of interference or feedback only happens to me when I don't turn everything on in the right order. That is computer on, Pioneer DDJ-SR on, open Serato, turn on subwoofer (passing the Eris 8's via the sub (Temblor 10), the Eris 8's on. No feedback, although there is very minute hissing. If I turn the speakers on first all kinds of hissing and feedback. That's been my experience. Not sure how you're using these but Hope that points you towards resolution.

A sub-woofer cable is basically a shielded RCA cable, it has no "right" way of hooking it up and no specific direction of current flow. The positive and negative signals are carried in separate parts of the cable, one connecting to the center pin and one connecting to the outer ring of tangs. These cannot be crossed by changing the direction the cable is hooked up so, unlike 2-wire speaker connections, it cannot cause 60-cycle hum by incorrect installation.

In most cases it's your cables. Depending on whether you are using the high impedance or low impedance outputs check the cables. Also try separating the place where you have the board and amp plugged in. Try putting them in them in separate wall sockets at two different points in the room. It may just be a 60 hz ground loop hum.

I am using the RCA line inputs and it sounds fine. All of the separate TV sound systems that I've heard have excessive bass response, which muffles speech when accompanied by music. With this system, the best settings for delivering clear speech are, using the remote control, set the subwoofer to minimum and select surround sound. There will still be tons of bass response.

I purchased this for a classroom that had a 3.5mm audio wall plate to speaker that was humming. It did not resolve that issue. For home components I would get a quality a/c line filter, or even try replacing the a/c outlet with a higher quality one. See PS Audio.

not sure exactly, but have you tried using a different cable and/or mic to see if the hum goes away? perhaps one of them is faulty.

Thanks very much to those who offered suggestions. Everything was fine with the wiring. A phone call to a Sony tech resolved the problem, which was found to be my selection of HDMI Passthrough to "ON". As such, the receiver remained partially powered in Standby and resulted in the hum. Re-selecting HDMI Passthrough to "OFF" cured the problem.

Sounds like it needs to be replaced. My subwoofer turned on just fine (little bit of a hum though).

Ground Lift changes the polarity so if you are experiencing "humming", switch the lift and this should remove any un wanted noise. Coaxial inputs are to plug in an external recording devise. Hope that helps you!

No humming or feed back issues with M850 cable. Have owned other monster sub-woofer cables that did produce hum. M850 is best one yet!

Could be cable / power point issue..the XLR cable will cut off the hum..( Balanced cable )..
