SOURCE: when amp powers up it makes a buzzing noise-quite loud-

Probably a loose coil or bad ground in the amp itself. Contact www.audiotekx.com, ask for Jason, he can help you and is the best out there. The problem you're having is extremely tricky to rectify, I had an amp with the same problem at it stumped multiple techs, some that had been in the business 35 years, yet Jason got it solved.

SOURCE: Buzzing in speakers on Carlsbro Marlin 8400 Power Amp

Hi,

If your volume is down and there's a hum, then it could be that your capacitors in the power supply are blown. Also there could be a problem with the bridge rectifier, possible that there's 1 or more diode's defect. Any technician can reapir that.

Hope it helps,
Gerard

SOURCE: nad c270 buzzing in amp

The buzzing is coming from the transformer. It is almost expected of an amplifier of this size, that the transformer (a large one) will excite the resonance of the casework and make some noise.

SOURCE: buzz from lexicon lx-7 power amp

Might be caused by any of the Large Capacitors in the power supply section of the amp.

Klh powered subwoofer model ASW10-120B... when you plug in to power... it makes a loud buzzing/humming noise


I would check the caps on the power supply. They are rather large electrolytic capacitors that will look like they burst and/or leaking. When these die, the caps ground and the sub will make a loud buzzing sound. If you are handy with a soldering iron you can replace them yourself. Replace them with the same voltage or a little bigger and same with the size.

If the cap. says 16v 4700pF on it, for example, a 20v 5300pF or a 16v 6200mF cap. will work for this application.

My speakers just out of the blue began to buzz in the middle of a song. The volume was low & did not seem to effect the buzzing - after I turned music off speakers began to make a high pitched ringing...


I've never worked on this model so I can't give you a definite part value or location, but you'll probably find a bad filter capacitor (or possibly more than one) in the power supply. The power supply converts the AC power line voltage to the DC (direct current) needed by the electronics. If the filter capcitors don't work, the result isn't smooth and steady, and the result is an annoying hum. You're probably hearing this.

It's possible to replace the bad capacitors, but it's not always easy. The people who make computer speakers don't often design them to be serviced, and sometimes it's a challenge getting into the power supply. But if you or someone you know with some electronic soldering skills is willing to give it a try, you might be able to bring these speakers back to normal. Good luck and thanks for using Fixya!

My powered mixer Behringer is buzzing


Make sure the buzz doesn't happen because of feedback of speakers into mics. When feedback is processed it often goes to a buzz instead of the usual howl.

Also check that you are running adequate inout into the effect since a very low inout will incur digitizing noise and loss of signal=to-noise ratio.

Carver amp started making a low fluttering sound.


I have a Carver amp which developed a "hum" also. As a troubleshooting step only (long term this is NOT a solution) you can use a ground plug adapter that removes the ground lug from the unit. This is an adapter that has THREE (Line, Neutral, Ground) female sockets for the amp to be plugged into, and TWO male plugs to go into a wall socket. If the buzz goes away, you've got a leaky capacitor in the Power Supply section of the amp. It will take some doing to actually fix the problem, but this will narrow down the cause.

Distortion/noise and buzz in front left speaker


Try to see if the reciever will make the buzzing/noise without anything connected to it except power, and speakers. Tune into a local radio station and see if the noise continues. If the noise has stopped, then you know there is an issue with the player or cable.

Speakers making loud buzzing noise


From your alternator, Make sure none of your RCA's are near a power wire, check your grounds as well.
