banasikdrummer Posted April 17, 2007 Share Posted April 17, 2007 In case you were an avid reader of my "crappy receiver = crappy sound?" thread, you'll know that I had been waiting for my Denon AVR-1906 to replace my Philips FR994. Well, it came in the mail today and I hooked it up. Although I hyped up how much better it would make my babies sound, I'm still happy with it, but I did have one question for you guys. With my last receiver, I noted how I could put my ear up to the tweeter and hear a slight fuzz when nothing was playing, which I was told to be normal. Well, with the Denon, the fuzz is still there, but it's incredibly more audible. What could be some causes of this? Quote Link to comment Share on other sites More sharing options...
Arky Posted April 17, 2007 Share Posted April 17, 2007 Better high current power? You haven't created a ground loop have you? Congrats on the upgrade! Quote Link to comment Share on other sites More sharing options...
kelA Posted April 17, 2007 Share Posted April 17, 2007 With my last receiver, I noted how I could put my ear up to the tweeter and hear a slight fuzz when nothing was playing, which I was told to be normal. Well, with the Denon, the fuzz is still there, but it's incredibly more audible. What could be some causes of this? Well with my Denon/Klipsch combination I hear no buzz whatsoever. Is the picture for your avatar how you have your system placed? If so, have you tried to move the RF35's further away from the TV? Maybe you are getting some stray interference from the TV. Not necessarily a ground loop problem. In a prior setup, I would get a slight buzz transferred to my RC3 from the TV when I had it sitting on top the TV.

banasikdrummer Posted April 17, 2007 Author Share Posted April 17, 2007 Now, the picture of my avatar was the first day I got my set-up and had it in my living room. Since then, I moved everything into my bedroom. Below is a picture of the bulk of my crap (RS-7s and sub are on the opposite side of the bed), which will hopefully get a response from someone saying, "You have way too much stuff in a small space." In a little while, I'm going to unplug everything except for the Denon and see if the fuzz is still there...if it's not, I'll know for sure the issue is all the power cords running by the speaker wires. If that doesn't solve the problem, though, I'll be back on here to complain and try to get some advice for what might be wrong. Quote Link to comment Share on other sites More sharing options...
LoudnClear Posted April 17, 2007 Share Posted April 17, 2007 get it to where the buzz is happening, then one by one, turn off the pc monitor, turn off the TV, shut down the PC, unplug inputs to the back of the receiver one by one until you have either heard the buzz stop or have nothing but the speakers and power cord connected to the denon. If you get to where the noise might be coming from a power cord, you might consider trying a power conditioner or trying to plug in the receiver and speakers in a different circuit in the house. Are there any flourescent lights anywhere in the house you could try turning off when the buzz is happening? Quote Link to comment Share on other sites More sharing options...
banasikdrummer Posted April 17, 2007 Author Share Posted April 17, 2007 Before reading this, I was in the process of turning everything off. I only had my Denon plugged into a surge protector that was plugged in near all this other stuff and the buzz was still going on. I'm getting ready to unplug the denon completely, move it across the room and plug in one of my speakers to it and check if the buzz still remains. I should post up again here in about ten minutes.

banasikdrummer Posted April 18, 2007 Author Share Posted April 18, 2007 Alright, I plugged the Denon into a wall outlet away from everything and ran some speaker wire to my left RS-7, which is the most isolated from everything, but the fuzz was still there. Is there a chance the factory refurbished Denon could be crap? I seriously don't know what else could be wrong in the last setup I tried, but I know that I don't like hearing fuzz from four feet away during the entire time my Denon is turned on...

Zen Traveler Posted April 18, 2007 Share Posted April 18, 2007 I wish I could help you but I don't have any solutions. I want to confirm that I have 3 Denon/Klipsch HT's and I don't hear an audible hum/fuzz from any of them. Quote Link to comment Share on other sites More sharing options...
banasikdrummer Posted April 18, 2007 Author Share Posted April 18, 2007 Yeah, I've pretty much convinced myself that the Denon has something wrong with it, because I went back to my original set-up but switched the Denon out with my old Philips receiver, which produced a fuzzy sound at normal volume that was just barely audible with my ear as close to the tweeter as I could get it, as opposed to being able to hear the fuzz four feet away with the lowest possible volume on the Denon. I don't think you guys are gonna be able to help too much on this one, so I'm giving Denon a call today along with e-mailing the guy I bought this from.

wuzzzer Posted April 18, 2007 Share Posted April 18, 2007 Banasikdrummer, Not to sound rude but lately when you've had an issue/question you've started topics in a couple different sections on the same problem. It might be easier for you & us if you stick with one area of the forum so that you don't have to go back and forth in all the areas that you've posted to find answers that people posted. That being said, I answered your post about this problem in the other area of this forum before I saw this one. [Y] Quote Link to comment Share on other sites More sharing options...

Yeah, I posted up the "I got my Denon" thread and asked about the problem before I realized that everyone who told me to keep them updated with my system was in the technical questions portion of the forum and not here. Had I realized that, I wouldn't have put anything in home theater and stuck with the technical portion, since my problem seem to fit there a lot more...

Speedball Posted April 18, 2007 Share Posted April 18, 2007 Denon being noisy? Not with my two Denon receivers, something crazy is going on somewhere. Hope you find the cause. Quote Link to comment Share on other sites More sharing options...
banasikdrummer Posted April 18, 2007 Author Share Posted April 18, 2007 Yeah, I've called a few people, and I'm either driving thirty minutes to a repair place or I'll have to ship it to Chicago, because something's obviously wrong with the Denon itself.

That's what I'm thinkin',all my Denons were very quiet.That was one thing I did like about Denon.I'd suspect most anything but the Denon,but anything is possible.

That's what I'm thinkin',all my Denons were very quiet.That was one thing I did like about Denon.I'd suspect most anything but the Denon,but anything is possible. At first, I suspected electrical interference or poor connections of some sort, which was eliminated when I both unplugged everything around the receiver and moved it to another part of my room and only hooked up one speaker with the fuzz still there. I also plugged in headphones to the headphone jack, and there was a somewhat audible fuzz from there too. Lastly, when I switched the Denon for my old Philips, the only hiss from the tweeters that was aparaent was either when my ear was as close to the tweeter as possible or when I was about a foot away but had the volume all the way up.

wuzzzer Posted April 19, 2007 Share Posted April 19, 2007 What type of adjustment for treble does the Denon have? Did you check to make sure that it isn't boosted way up? {edit} On second thought that shouldn't really affect any hissing you're hearing with no signal going to the receiver. Just trying to save you from having to ship the receiver in for service. [] Quote Link to comment Share on other sites More sharing options...
banasikdrummer Posted April 19, 2007 Author Share Posted April 19, 2007 Well, I appreciate the thought. I thought about the treble too (before I disconnected all the inputs), but it and the bass were both at zero. As for shipping the receiver in, though...I e-mailed the guy I bought it from and he says if the service center about a half hour from here won't take care of it, he'll send me a prepaid shipping thing to put on the package so I won't have to pay any shipping. So at least all isn't bad... Quote Link to comment Share on other sites More sharing options...
wuzzzer Posted April 19, 2007 Share Posted April 19, 2007 I hope you get it all worked out quickly. I know if it were me I'd be impatiently waiting for everything to get resolved! Quote Link to comment Share on other sites More sharing options...
banasikdrummer Posted April 19, 2007 Author Share Posted April 19, 2007 Haha, impatience is a constant feeling...I just hope to keep away from getting too frustrated with customer service people that give me the run-around. Quote Link to comment Share on other sites More sharing options...
