NOO!!! Buzz problems

[Dalus_Carosu]

Like the Topic say

Got 1068+1095 and get a strange buzz noise in the speakers dont matter how low I turn the volume down

I only got 1068+1095 and a CD player connected?

Anyone have a clue what the problem can be?

Anyone have a clue what the problem can be?

Something on your house electrical path is dumping noise into the line that the Rotel is picking up. Are there any lights (esp dimmed ones) on that line? What else shares that power line?

[Dalus_Carosu]

Damn Rotel to picky

I got all connected on same how you call it a box that has 6 connectors Ehm not good at English.

[Dalus_Carosu]

Ok not working at all now

The 1068 is getting warm like hell.. and now I got no noise at all

[Andrew Pratt]

Hmm that's not good at all! By not working what exactly do you mean? Are there lights coming on or not?

[Dalus_Carosu]

You can turn it on both the 1069 and 1095 but there is no sound at all its completly dead :cry:

[Dalus_Carosu]

Ok working now and pls dont ask me what it was my Fault lol.

But still Buzz problem

Only thing I miss from my Old Harman Kardon is the Bass that Reciver had alot more Punch :T

Best thing to probably do is to test all your connections, one at a time pull them out and see if it stops the buzzing problem.

I have had no ground loop issues with my Rotel gear, but I did find out how easy it was to induct a ground loop into my system.

I had all 5 RCA pres from my Pre to the amp plugged into the Pre, but only the front three into the Amp. All I did was touch one of the connections to the back of the amp (was moving wires around and it touched) with only the Amp on, not the Pre...and I got the buzzing sound. As soon as I moved the cable, it went away, and as I grabbed the end of the cable, I could cause the buzzing with me just touching the tip. So it goes to show how easily it can be induced.

I would seriously just try removing each and every connection until you find what is exactly causing it...then once you do you can work to remedy it. As long as you have good connections and decent house wiring...you should be good.

[Dalus_Carosu]

Yes but I almost dont have anything connected Just 2 speakers - 1068 - 1098 - CD.

So I cant disconnect anything or I cant get sound

[audiofan]

I took a suggestion by taking a piece of speaker wire. connect one end to a srew of your pre-amp and one end to the screw of your amp.

It works for me.

Try different power points. I get different levels of hum depending on the power point connected to. Its a pain but it's a combination of your house wiring and the other things connected to it (like fridges, microwaves, other hT gear, STBS etc!).

Is it possible to connect the CD player via an optical cable, this will eliminate the electrical connection between the two units.

[Azeke]

Just a quick question, do you have cable?

If so, disconnect, and test.

EMI could be the culprit.

I have for one have given up. I can take the system down to bare bones and eliminate most of the 60Hz noise but have been unable to elimate it with a complete system. Believe me... I have tried everything!! This is my biggest niggle with rotel gear.
I find that driving jeeps and land rovers for years has made me capable of amazing feats of overlooking faults... fringe benefit: helps the marriage work better also...

Thats a pity you have had problems with your Rotel gear. I use a good filtered outlet on a dedicated circuit, and have not had any problems with AC Hum. As others have said bonding the units with an external earth can help, for me I would rather cure the problem the AC problems with a decent filter, and dedicated circuit.

Check these threads out...

Dedicated Circuit

Mains Filter

[Dalus_Carosu]

Ok gonna test some more when I get home

[Dalus_Carosu]

Oh well nothing to do then buy a Monster Filter and try it out

If its not that then I dont know hehe

I just tested some when the volume is on 0 then I have nothing then its Off. When I turn it up just 1 I get the Buzz/disturbance and it don't matter if I have the CD connected or not? I can understand If I get it at higher volumes but it shouldent be anything at all that low

[KEN KAZ]

ive had my 1068 and 1095 for 2 weeks. no buzz till yesterday.

yesterday Direct tv came and upgraded me to HDTV. now i have lots of buzz. i just lifted the grounds. problem goes away.

[PewterTA]

Make sure too that the cables you are using a a good shielded cable...

I use all Belden cables with Canare ends and have no problems...but I found out if I touch any of the ends I can induce ground loop into my speakers (and amp)... So it just goes to show that you can have interference with the slightest change...

[Dalus_Carosu]

I am using Supra Dac as Signal Cables not bad at all

[Dalus_Carosu]

Hmm the buzz go down a bit if I use Bypass not Stereo Mode when lissening to CD

Wireless Networking Gear - BEWARE!

Be careful of WIRELESS PC/ROUTER/MODEMS etc!!! - I hooked a wireless bridge up to my Xbox (which happens to be next to my HT gear) and the interference caused an enormous brrRRrrRRrr/buzz! The noise went away when I moved the wireless bridge a couple of foot away from my equipment, but that defeated the purpose of the wireless in a way so I took it back to the shop and am simply wired again (the wireless "N" specification which is still coming is supposed to be better regarding interference?)

--> my best friend had exactly the same problem with his PC speakers next to his wireless gear and we both have "Netgear" equipment FYI (he had the 54Mb and I have the 108Mb version) ....reason I mention this is because a lot of people have HTPCs these days!

Anyway, generally a buzz on hifi is caused by earthing loops, light switch dimmers or old refrigerators from my previous research on the buzz factor?

* The most common buzz is caused by earth looping, and a nifty trick, if you have a radiator in your home/room, is to connect the raw end of an insulated wire to a screw on the chassis of your amp or receiver, and connect the other end to a bare section of metal on the radiator, which contains water, which inturn touches "earth".

[Dalus_Carosu]

Maybe I am just imagining this sound maybe a little buzz must be in speakers?

Because I have unplugged everything I got in the House and every light '

And still the same..... Ok time to go Crazy :M

[Bob Knarly]

Don't go crazy,just unhook everything.Plug units in,listen for buzz,hook up speakers,listen for buzz,connect each cable and listen for buzz.Try to locate the cable you connect that makes the buzz start.good luck.

[ti33er]

Dalus Carosu: with my old NAD system I also went crazy trying to get rid of the buzz = sleepless nights, losing hair, low labido etc. ...funny enough, upgrading to ROTEL got rid of my buzZzZz problem in the end!!! ;o)

Anyway I fully understand "going CrAZzy" - someone even recommended that I might have a loose plug terminal in the house (I take it you know that all power in your home runs in a big circle) and should take apart EACH plug, check the wires were contacting properly and using cleaning solution on each and every part of each plug interface! - you gotta be crazy, as you can imagine I didnt embark on that nightmarish venture!!! HOWEVER --> I did find that connecting my old NAD system through a full size Compaq Server UPS at work (which can sustain high Wattage) did remove the buzz - but I was not prepared to buy one of those and have it in my living room i.e. it cost a bundle and was the size of a truck, full size server rack mountable unit! hehe

Anyway, I would also recommend getting a second identical ROTEL unit from your dealer on loan to test if your gear isnt perhaps a little screwey! (or take yours into your dealer and compare)

ti33er -

I have the Netgear Ethernet Bridge 14" from my RB-1080 and do not have any issues at all. I run my PS2 off it connected to the Netgear 108 Super G Wireless Router - no problems at all... Often I have my laptop (connected at 108, the bridge will only go 54) very close to this set-up and have never heard any buzz or hum created by it.

Go figure - finally something goes my way! :T

Cheers,
Keith

Like I said tried everything.. I mean unplugging every device in the whole House then just connectin speakers to the Rotel without speakers I still get the Buzz in the lowest posible volume = 1. Not much but still it shouldent be there then when I turn up the volume it just get higher and higher after 65+ in volume you can hear it clear

I am just living on the hope that the Voltage power filver will fix it or... :M

[Dalus_Carosu]

Yeah forgott to say I am getting 2 new Untites the 1068 is on lone before mine comes and the 1095 I got in the wrong color lol. So both will be replaced
