When I go to full volume on the amp and no music is playing, I hear white noise from my left earphone. Is this normal?

Just tried it with my Sennheiser PMX 100 and HD280 pro headphones and got nothing. But I have noticed at times some strange static through the headphones as I move around at my desk. I can't pin it on the ICON, but it only happens when using it... so maybe that does pin it on the ICON...

This sounds like a problem with the connection of either the headphones or the ICON. To isolate the problem, plug you headphones into a different source to check them out. If they sound ok, the the ICON has a bad connection in the headphone connector, or elsewhere in the unit. At that point, contact Nuforce for warranty information.

No, it's not normal... Make sure that everything is plugged in correctly(power cord, aux cable, etc.). And make sure that you earphones and your music device are capable and functioning. If nothing works, contact Nuforce and tell them that you got a defective product and they will help you out.

I don't know what is particularly wrong with your left speaker. I can just admit, that the cheep Fostex PM0.4n has no protection against overloading, as for example the expensive Genelec has... Sometime, I wish to play my Fostex PM0.4n louder, but I can't. They start clipping making noticeable clicking sound.

Mine produce a little noise too. Actually,I just bought a second unit and just send it to the technician since it move my left speaker when it turned on.

I heard a lot of noise as well, that is before i bought a dedicated audio interface, like an m-audio m-track, preSonus, focusrite, etc.. If you're not using one, then i'd say get that first. I have no noise now at all settings. From -30db, and i usually have my speakers set at the +6db and nothing. i'm also using the 1/4" to 1/4" plug into the balanced inputs. If you're using an audio interface, then i'd say call customer support and get it fixed.

idk, it could be a multiple of things, my guess would be, play one side of the deck and swap the needles to see if it still humms . you need to find out if its the turntable or the mixer first. try to plug in turntable straight into the amp without the mixer to see if it still humms, if so, maybe the red and whites,ground on the turntable are bad.. it could be your main red and white cables from your amp to mixer, check to see if your amp humms without dj setup connected to it, does it humm when your listing in the headphones??, maybe reinstall software.. i know this stuff is a real headache, especially when u pay top dollar for an item like this, goodluck idk, it could be a multiple of things, my guess would be, play one side of the deck and swap the needles to see if it still humms . you need to find out if its the turntable or the mixer first. try to plug in turntable straight into the amp without the mixer to see if it still humms, if so, maybe the red and whites,ground on the turntable are bad.. it could be your main red and white cables from your amp to mixer, check to see if your amp humms without dj setup connected to it, does it humm when your listing in the headphones??, maybe reinstall software.. i know this stuff is a real... » Read More idk, it could be a multiple of things, my guess would be, play one side of the deck and swap the needles to see if it still humms . you need to find out if its the turntable or the mixer first. try to plug in turntable straight into the amp without the mixer to see if it still humms, if so, maybe the red and whites,ground on the turntable are bad.. it could be your main red and white cables from your amp to mixer, check to see if your amp humms without dj setup connected to it, does it humm when your listing in the headphones??, maybe reinstall software.. i know this stuff is a real headache, especially when u pay top dollar for an item like this, goodluck « Show Less

Seems like it might be a flaky ground connection. If you've tried other headphones, and if you don't get a buzz when you plug your guitar into another amp, I'd guess that the AmPlug has a faulty ground connection inside, most likely at the 1/4" phone plug.

I usually never had that problem unless I pushed them too hard, I bought two of these amps, each one pushed a mofo 12" sub. When I got one of them it seemed like something was rattling inside of it, like a peice of metal. Opened it up and sure enough it was. Check the amp, check all your connections, and play with the settings according to your music type. It also varies what your sub or subs your pushing. My best answer is in your connections. See if that helps. Like where your ground is located and how good your ground connection is. But factory defaults do happen, especially if they are cheaply made and mass produced.

Yes, and to be honest I think that it is normal but I'm not a professional, every stereo system I have ever owned, has done that. Only at very low volumes.

Mine is quiet. You should not have noise. Turn volume down. See instructions.

Yes. It is normal. If you need better sound proofing, you should get a closed back headphone instead...

Check all the cables sometimes is that. Also maybe could be dust. Try other speaker with the amp if you can.Hope that helps.

I am having the same problem (I hadn't noticed the volume level though). Anyone have any ideas?

no it is not ...it has to play loud ever with the half power . Except if you loudspeakers have very low sensitivity ...lower than 85 db. Check also the settings of your phone and your pc , especial the phone volume could be lower when you connect it to headphones in order to protect your ears .Also try different interconnect cables sometimes they dont fit well. If it nothing of them then probably your AMP is faulty

Did you adjust the screw adjuster under the rubber plug. I typically turn it clockwise until it stops and the back off a little. I have also found that not all MP3 or IPODs put out the same supply power. I had an IPOD hooked up to one amp and the volume was allot lower than what I was used to. After much testing and adjusting I tried a different IPOD and it was back to normal.

Mine did the same thing. Not sure if it's a good/bad thing but the amp is good. Hope this helps

Mine isn't loud. I would not consider it normal. Contact the seller for an RMA.

Yes there is a hum (slight). What I hear is constant; no matter what volume I am set at. I actually had to exchange my first set due to amplifier 'popping'. Again, volume setting did not matter. I have decided not to let this hum problem bother me because it is inaudible when something is playing.
