Problem with my RF-35s????

[NickJames]

Hey everyone. I bought the R-35 speaker package with a RW-12 subwoofer and have set up the RF-35s and the RW-12 in my room. I am currently powering them with a Pioneer-Elite VSX-82TXS 7.1 reciever. I am running Monster M-Series speaker cable to them.

Anyways, the RF-35s sound great listening to music, they are very sensitive, bright, loud. But I have noticed that when I have no signal running to them, so let's say I am on the SAT or Game input with no satelite box or console....whatever...I get a static buzzing sound coming from the horns on the RF-35s. I sit about 8 feet from them so maybe that is how I noticed it. So then I checked if I could hear it while playing music through my ipod through my reciever and I could slightly tell. I am wondering if anyone else has this with the horns on their reference series speakers or is it just mine. Do you guys think it has something to do with how I set them up with the reciever or could it be a something else in my house (it is an old house, early 1900s) like electrical wiring, ect? Or is it that the horn is just that sensitive and I am being overly critcal? Was going to call Klipsch about it but I thought I would post here first and get to know the Klipsch consumer family. So if anyone has any advice, it would be very thankfull.

Other note. All devices plugged into a Monster Powerbar. Used an older Sony reciever and had same problem. Moved speakers into different room, same problem. Have not set up center channel or surrounds to see if those horns make same sound.

Very unlikely that the speakers are the problem. I would lean toward

the receiver being the problem, except that you tried another receiver

and had the same results. Do you still hear the buzz with the volume

turned completely down own your receiver?

Could be a grounding issue, are you running the sat coax cable through the monster bar. it should eliminate 90 percent of the buzz. Try disconnecting the sat line and play a dvd or cd because cable and sat can cause a hum or buzz.

Klipsch speakers are famous for being sensitive, they are extreamly sensitive to noise. That noise may be from amps, surround sound processor (DSPs), sources, and other things. Recievers like the Pioneer-Elite, don't have the quietest amps or DSPs, so some "hiss" (expecially from the horn) is natural. You can isolate the noise coming from the DSPs by changing the surround mode for a given source. You will likely notice the DTS and DD modes are quite different in "hiss" levels as compared to "stereo" or other modes.

I had simular problems when i purchased my first klipsch speakers and a Denon reciever. The Monster Powerbar may be making more or less hiss. My old triplite surge protector actually added MORE hiss, however, my Monster reduced the "hiss" compared to a direct connection. When i upgraded my Denon to seperates, the hiss reduced so far i could barely hear it when i had my ear 1ft from the speaker.

So I'm afraid its just the nature of the Klipsch beast.... You will likely NEVER notice the hiss when watching movies or listening to CDs.

Hope this helps...

Hey, thanks for the info guys. I am on my work break now, so I will have to be fast.

"Very unlikely that the speakers are the problem. I would lean toward the receiver being the problem, except that you tried another receiver and had the same results. Do you still hear the buzz with the volume turned completely down own your receiver?"

Yes with the receiver turned down, I still hear a slight buzz.

Also I have no cable wires or anything right now, and actually do not even have a DVD player hooked up at all, so I have not tried movies. Like mentioned I am sure it will be hardly noticable when I play them. So I guess I would just take some more advice if anyone knows how to reduce the buzz...if I can. Thanks again for the help. I should be getting my center channel and surround speaker cables soon too, so I will be able to find out if they will make a similar buzz.

Try plugging it into another plug. One that is not on that breaker. Check to see if the speaker wire is not running along side of a power cord. If this don't work I call Monster and talk to the Tec support.

One thing to do that's a little tedious but might help you pinpoint the problem is to turn off the receiver and unplug the RCA cables from one of the devices connected to it. Then turn the receiver back on and see if the buzzing is still there. If so, turn off the receiver and reconnect that device and try unplugging a different one and repeat the same process.

If you find the buzzing is eliminated or reduced with one of the devices, it might be a good idea to get some better quality shielded cables for it. Another thing that's helped some people is if you determine that the buzzing is coming from a certain device, plug it into your receiver's convenience outlet in the back of the unit and see if that helps.

Hey looks like I may have figured it out guys. Kind of a stupid thing I did not notice. So I unplugged everything possible that could be causing the buzz around my reciever/speakers. Anyways while I am unplugging things, I realize that the small light on my MONSTER Powerbar that reads "Ground OK" is not green...it shows no light at all. So I look online at the Powerbar manual and in troubleshooting it says,

"Symptom: Speakers emit a humming or buzzing noise. Possible Cause: The Powerbar is sharing AC power with equipment that is not properly grounded."

Anyways, because my house is old I am guessing that the outlet I have my bar plugged into is not grounded. When I hooked up the RF-35s downstairs on my old sony I only used a basic power strip bar but I would assume that the outlet I had it into was not grounded as well. So, right now I will take the Powerbar and go to remodeled rooms of the house that could have a grouded socket. If I get the green light, I will hook up the reciever and speakers and see what happens. I will write back when I am finished. *Crossed fingers*
