Yeah, that sucks. I figured it out after I couldn't return them anymore. I just gave them away and bought a much more expensive one to replace them. I got a Crown 28M to replace my two Pyles. It has been on for about 4 months now, and never hummed. I needed an always on system for PA work.

You're impededences are not correct for your speakers and amp. Look online for the wiring diagram. I found it easy. And make sure you are providing a good ground for it.

Check your inputs, good Mic, good cord & connections ect. Use a new or known good mic & cable. Then check speakers & wiring for damage or loose connections. Make sure speakers are connected correctly for their impedance (marked on speaker). User manual should help. If this amp has a radio tuner, make sure it's input (Aux In) is turned all the way down. Also turn down any inputs without a mic connected. If these steps don't fix it, then you may have a bad amp(s). There are some known quality problems with this brand.

sounds like it has a problem, there should be no noise coming from unit, contact manufacturer or place of purchase.

Thank you! I finally solved the hum problem by plugging the iMic into "Line Out" on my amplifier instead of directly into my turntable. The hum disappeared! Hope you got your hum solved, too. Maria

Consider the size affords moving to an area where spurious electrical signals would be minimal. Use an outdoor extension cord to move as far from any building as possible. If the noise continues then the problem is from the internal electronics. If the hum is gone then the problem is coming from the area where you normally use the Bose. You need to find what the problem source is by turning off all the electrical apparatus near to the unit.

Whenever you get that dreaded hum, be sure to check your ground connections.Could be something as simple as trying out a new instrument cable.I've even had some brand new cables with an open ground.You may have to re-solder the ends.

You know I had to go and check! However, I have an 828LM and no hum whatsoever. Have you unplugged (the replugged) the unit and tested it away from other equipment for this humming noise?

Use fresh batteries. It will provide a good shock if your batteries are new. You will also hear it humming louder at the control box.

I haven't experienced that with my unit. Sounds like you need to contact customer service.

If it makes a quiet humming sound when you have your audio device plugged in/playing, the speaker is more than likely damaged. These speakers should be covered under 1-year warranty, but you will have to pay the costs to ship the speaker to Pyle's New York address (this is what I was told a few years back by a customer service associate). In my opinion, these speakers are more trouble than they're worth. Mine had about 3 months of regular use on the weekends (never anything extreme), before this happened. Hope this helps.

I've had best buy out twice now. The first time to replace all the screws in the back of the tv and that helped for about 1 week and the buzzing or humming sound came back. Best buy came today and replace one of the boards on the tv and i'm hoping this will fix the problem.

OK!........4 or All of mine are making sequel and crackling sounds when a phone call comes in. I was told to unplug the charger and let it set for 15 minutes and then plug them back in. They are still making large crackling sounds and squeals! Now what should I do because I purchase the 6 set through amazon. The one out in the shop I doubt is a problem so I'm not worried about #6! Up until last week everything was great. Now I'm having problems and I put in new rechargeable batteries but I still get the screeching and scratching noises! Bruce HartogWildwood, FL 34785

The reason you are hearing the hum is because your transformer plates are slightly loose. The metal plates in the core are laminated and can become separated, you may be able to reduce or eliminate the hum by painting a varnish or shelac onto the core and letting it "soak in". I would suggest several thin coats to do the job. The metal core itself can be loose and vibrate as a whole too so you may need to seal that up the plastic bobbin that the copper windings are wound on. Otherwise if all else fails this unit is quiet, at least the one I got is. You may also try insulating between the transformer and the joist if yours is mountable that way. Hope that helps.

Ground Lift changes the polarity so if you are experiencing "humming", switch the lift and this should remove any un wanted noise. Coaxial inputs are to plug in an external recording devise. Hope that helps you!

Never have heard anything , but hums or noises could be resistance... either from outlet or heater unit itself.... but noise shouldn't happen.... prob wanna get that checked

Sounds like a malfunction. Mine is completely silent. I would send it back.

Radio shack also sells ground loop.isolators or you can build your own from a 1:1 transformer this should also fix the hum as well.
