Noise when volume above 0dB. Help

[alpharetta]

Dear All:

I am setting up my system and experiencing noise problem as below:
I have not hook up the brand new Yamaha receiver V2500 to any source yet. I so far connected the two front speakers(M60) and Subwoofer (EP 500) to the receiver. I used the Axiom banana plugs, Sound King 12 gaue wire, and Axiom subwoofer coxial cable. The speakers are from Axion and they are brand new too.

When turn on the volume of the receiver to 0dB or above, I hear the soft noise produced from all the speakers.

What it could be? Speaker issue? Receiver problem? or cable Wire?

Thanks

It's normal background noise. Most likely, you won't be turning it up to "0", and if you are, then you need more power.

That's probabally normal. Is it a quite hiss (white noise)?? Or is it quite audible noise?? It may just be the idle current causing that noise.

My room was about broken when volume turned to 0 dB

Thanks Guys. Your quick responds really relieve me a lot. It's the hissy noise (white noise) like the snake sound.
I hook the receiver to DVD players and turned volume to 0 dB, man, my room just was about broken. So I had to turned it down to -15 dB. Definetly I don't need more power, since the Yam 2500 can go max to 130 Watts.

Interesting thing is that when I pause the DVD player, I don't hear any noise at 0dB volume level. But when I turn off the DVD player, the white noise streams again.

What could be the best explaination? Do I need to fix or adjust anything?

Thanks

.....Alpharetta, is your receiver anywhere near a window to the outside with dirt/Earth below the window?....if so, run a single strand, unbroken if possible, of that Sound King speaker wire from the ground post on the back of the receiver out the window, strip the outside end back about six inches, spread the stripped wire, and bury the stripped end about a foot deep in a hole you just had your wife dig with a shovel....fill the hole with water with the spread-wire-end laying in the bottom of the hole....fill back in dirt to level plus a little.....go turn the volume of the receiver up, with no source chosen, all the way up, and see what you get....then you can back out a screw from the chassis on the back of your sources, and run a wire from them to the ground post of the receiver....any slave amps also by the same method....your $500 dollar speakers will then be worth $800.......

Please tell me you are kidding, mulester.

Please tell me you are kidding, mulester.

.....MDS, if I could, I would, 'cause I like you....really....you think it's better to ground your system to the house's electrical wire network which can act like one big antenna for interference and radio signals?....sure, it ends up going to ground, but I get there real quick....water that hole, MDS, water that hole......

I'm not going to argue the merits of grounding your audio system in such a manner...but mule, if you really want to make this type of ground work better you really should put rock salt in the hole prior to watering, and then more rock salt on top of the hole once it's filled and water the hole again. If you really want to go all out you can can take some PVC tubing and drill some holes in it, fill it with rock salt, and cap it off. Bury this in the hole and you have yourself a nice slow release system.

.....this is quite probably a very good suggestion, Nibhaz....I will consider doing that on the next one whenever that may be....my present grounding gets watered on a regular basis whether it be a shot from the ole' water hose by day, or whizzing on the top of the dirt at night, haha....truth....MDS and Nibhaz, when I first started doing this type of system grounding back in about '75, I have never had the first indication of noise or interference whatsoever since, gains full with no signal.....humor me already, please......

Its normal, don't worry about it. You won't hear it once the source is being played.. As far as hearing the noise when the dvd player is off, could be due to the receiver picking up interference and amplifying it. As long as your not hearing the noise from the seating position don't worry.

alpharetta,

You never did mention how close you were to the speakers when you hear this his as well. I have the 2500 with some very sensitive speakers (Klipsch) and I have never heard a hiss at 0 dB from my listening position (6.5 ft from the nearest rear speaker - Def Tech BP2X, 14 ft from the nearest front speaker - Klipsch RF25) with either the recievers internal amp or after adding external amplification. If though, I would walk up to a speaker and put my ear right by it, I would hear a very slight hiss that will disappear if you get 1 to 1.5 feet from the speaker. My unit is connected to a dedicated 20 amp circuit which is also shared by all my sources (as they all draw very little power). Each amp has its own dedicated 20 amp circuit and the projector has its own 15 amp circuit. I also run every dedicated circuit through its own separate line conditioner and I have never had a problem with any ground loops or humming in this fashion.
