If the noise is accross all channels then it's most likely the large electroltic capacitors in the power supply. These filter out the mains hum 50/60hz. There might be two or more they will be the biggest! Even if you can determine only one has gone, it's best to replace them all.

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.

Monitiors are not turning on


Have you tried to use these on other devices, like a DVD Player, etc.? If you get a HUMMING noise with other devices then the internal amplifier is defective and you are not getting sound production to the speakers. If you have separate power AMP and the speakers hum when connected, they may have been damaged. If you have a speaker mismatch; they tend to buzz, thus too many conditions could represent the humming. Check that the Positive and Negative polarization of the speaker wires are correct.

Mackie DL 1608-1 channel hums w only 1 guitar


Generally the hum is one of two things. If a sensor, pickup, per-amp, or mini-amp are too close to the receiver or speaker, Feed-back may occur or a hum and buzz join the audio signal out. The usual problem is: line in port on the instrument can be defective or the male jack is not making proper contact. If a cord is tested and working, the condition is in the input on the instrument. If a terminal has a loose wire inside the instrument the problem can be intermittent ( come and go) and thus a buzz or line noise may be present.

BUZZING NOISE LIKE 60 CYCLE HUM, CHECKED CORDS AND MIXER AND POWE


When the speaker is connected only at the power line does it makes this noise?
  • If it does it's an internal amplifier's ploblem and you have to check out some fittings (electrolytic capacitorsat the power supply, power supply transformer, voltage stabilizers e.t.c.)
  • If the speaker is quiet you have to check your external wiring because there is a loop ground. That means that one "ground level" line is connected at the ground by two or more cables (e.g. the audio ground and the grond from the mains power source) In this case disconnect the second (and the 3rd e.t.c.) grounding point.
In case of a problem or clarification, don't hesitate to post me a reply.

Iassume you mean you hear the buzz independently of the audio program - simply connecting the cable causes the buzz?

If tanything in the mix is powered from different AC sources you may have a different ground potential. Sometimes manipulating the orientation of one or more ac plugs will solve hum problems.

The noise is a hum or buzz. We've narrowed it


Hello,

By chance have you tried making sure the laptop is not too close to the speakers? Sometime you will get feedback when the source is to close to high powered speakers. Also, check your jack cord and make sure no splits/cuts are visiable and the plugs are fully inserted.

Good Luck and keep making great music. Aloha.

A couple of weeks after initial setup of my brand new Onkyo XT-SR606 receiver, I noticed a loud buzzing noise that starts up approximately 10 min after the receiver is turned on. The buzzing is definitely...


The "buzz" you hear is a power hum made by the power supply transformer. It's technically called "Lamination hum" caused by the revering of electrical current through the power supply transformer. In some cases the hum can vibrate the chassis causing other loose material to vibrate. If you can, go to your dealer and check to see if other units of this same type typically make a hum this loud, and if not, see if he can solve the problem for you.

Buzzing noise


The buzzing you are experiencing is most likely the electric valve solenoid coil.
That is the valve that lets gas in when the stove is turned on.
Another source of buzzing/humming can be a mechanical clock, if hter is one.
If it is digital, then it woul not make noise.
