I hooked my speakers up to my new receiver and I am getting a slight buzzing noise from my surround sound back left speaker. Its very faint but noticable. You can hear it when the volume is down very low. I know its not the speakers because I switched the SBL and the SBR outputs and the noise followed it to the right speaker. Just wondered what you thought the problem if and there may be. I tried seperating cables and everything so I'm looking for some other ideas. Thanks
the buzzing moved to every channel I plugged it into. I plugged every speaker I had into that one output. The speaker wire was brand new. Did I send it out for repair for nothing?
ok let me start again sorry. I plugged all my speakers in and heard a buzzing in my SBL speaker. To troubleshoot I plugged other speakers from other outputs into that output to see if it would follow and it did. I don't know if i'm explaining it correctly but i think thats what I did. Maybe you can clarify it for me.
Did you try to test the wire by swapping wire connections in the back of the receiver, or just move speakers??
By moving wire connections in the back of your receiver, you could have determined whether the receiver was the problem or not. Since you already determined the speaker wasnt faulty, if you connected the (correctly working SR wires) into your receiver SL output, you would instantly know whether the receiver was at fault.
I was wondering how you like the VSX-815. Does it have a fan or did you not notice. My VSX-814 does and I may return it for a different receiver because of that.
Hi guys, I'm having the exact same problem as David, I have tried switching out speakers, using different power sources, and different wires but I am still getting the buzzing sound. Except mine is coming from my surround back right speaker. I wonder if this could be a common problem with this receiver? I'm going to go back to the store today and exchange it for another one.
Just an update for you guys - I went back to the store and exchanged my Pioneer VSX-815 for another one to see if the speaker buzzing problem in my surround back right speaker was still going to happen. Turns out it still does, but it wasn't as loud as the first vsx-815 I had. However it was still noticeable if you were the person sitting directly in front of that speaker. It makes me wonder if there is a problem with this specific model of Pioneer receiver. I'm going to take it back tomorrow because i'm afraid that the buzzing might get worse down the road. If anyone else has had this happen with any other brand's 7.1 receiver please let me know. I'm curious if this is considered normal in a 7.1 system or not?
Hi Paul, i've tried using different speaker wire which is brand new, and also have tried 3 different sets of speakers (all different brands) and the problem still persists which leads me to believe it's the receiver. I've decided to go back to the store tomorrow and return this one and upgrade to a Pioneer vsx-1015 since i've heard good things about it. I'll let ya guys know how it turns out.
hey Reg I can't hear mine unless i have my ear right up to the speaker. Is this the same with yours? Being that its the back 2 speakers I have a thoery the buzz comes from the matrixing the speakers to sound like 7.1.
Hi guys, you can hear mine even without your ear up to it. You just have to be about 2 feet away and you can hear it.
Having said that, I just got my brand new vsx-1015 and it works like a charm. No more buzzing at all, and i'm using the same speakers and wire. Yay! So it looks like it's the receiver after all.
I guess NAD owners commenting here are so used to their NAD humming and buzzing sounds, they think it's natural and they believe all receivers do it.
My yammi produces absolutely none of those unwanted sound effects.
And yes, as it relates to HT, the CVs will blow away your halfpint itty-bitty speakers that claim to be "Loudspeakers". A definite misnomer equal to king of all misnomers(parkway & driveway).
Why do you park in a driveway, and drive on a parkway???? The same goes with boutique 'loud'speakers.
David: this problem happens ocassionally in all brands of receivers. Normally when the receiver is idle, powered up but no source playing the speakers should be completely silent. In some instances with your ear pressed upon the speaker you may hear a very faint "hiss", this is generally acceptable, but you should not hear any AC hum or "buzzing". There are only two reasons for this 1) there is a ground loop present in your system and 2) there is a problem with the receiver. To check for ground loops disconect everything from the receiver all cables and equipment EXCEPT the speakers. If the problem still persists with only the speakers connected then it is the receiver. I sent an older model HK AVR I have to Inhouse Stereo Repair in New York and it's been there about a couple of months and they still haven't determined the problem. Problems of this type are very complex in nature and require sophisticated equipment to diagnose. Fortunately I did buy a new HK AVR to replace it so I don't have to live without stereo and surround while the other is being repaired. As I expected the new AVR is completely silent. Some on this forum would suggest that the problem is caused by a failing capacitor in or near the power supply or filter section for the amplifier but this doesn't seem to be the case. The last time I telephoned the technician he said they were going to check all grounds within the unit. That was a about a week ago and I have not heard yet from them.Suprisingly, This type of operant noise problem is commonplace in television sets. If you find a tv with a totally silent power supply let me know so I can rush out and buy it.
well I just e-mailed pioneer about the problem with this receiver and i'm hoping to get a response back. The chances are probably slim. I asked them to look into the problem. I will let you guys know if I hear back from them.
I wouldn't hold my breath David on that one. I discussed the problem with HK's tech support and they gave me a spill on noise floor and how some is present in nearly any receiver. This is true to a certain extent, as I said with some very faint hissing generally being acceptable but any AC hum/buzzing is not.
i should probably go try and return mine then. This really stinks.

Hey all, I just bought this pioneer vsx-815. I'm lovin it. Anwyay, I use a 5.1 setup, it sounds like the buzz your referring to is in the surround back positions. I'm going to plug my surrounds into the back to check.
How do you guys like the pioneer receiver? What speakers are you running into them?
Do you guys use the MACC configuration? (with the mic and the automatic setup?) That seems pretty cool, but I tried it twice in a row from the same location and it set up the distances a little different. The subwoofer level was set a little lower than I like too.
Just curious on everyone's opinion with this receiver.
Hi Pirate, yep I have a 7.1 configuration and the buzz was coming from the surround back right speaker for me. Other than the buzz I thought that the receiver was great and that if you can find one without the buzz you have a great receiver on your hands.
I used the MCACC automatic setup to do the initial tuning of the receiver and then I used the manual setup mode to fine tune the settings to my tastes after that. Hope this helps.
David, I have also posted my experiences with the vsx-815 on another message board and two other people on that forum have also reported experiencing the same problems.
Also for the record, I also unplugged absolutely everything from my receiver except for the speakers and still encountered the buzzing with both vsx-815 units I had tried out.

Hey Reg. Does the 1015 have the same sound effect options as the 815? Under both standard and advanced? Just curious as to what all of the differences are between the two since you've had experience w/ both.
Hi Pirate, it has all the options plus it has another button called 'THX' to flip into a variety of THX modes.
You can actually compare the two on Pioneer's website by downloading the pdf manual for both. You'll be able to see a complete list of the modes and features in it.
Reg and David: Talked to the tech guy today at Inhouse. Turns out the main power supply caps have shoddy grounds and he's going to resolder them and hardwire new grounds, this will take care of the buzzing. Unfortunately this is going to cost me $98. So if you ever buy a new receiver with this problem RETURN IT IMMEDIATELY! Just wanted to let you guys know.
