Wrong answer, at which frequency do you hear the buzz . And does it happen with more gear on. And do you here a buzzing sound coming out of the unit, WITHOUT put sound on it.... Probably a defect transformer, put that's why i want to know if the buzz or humm is a constant and pls turn out saving lamps and led lightning.
gr richard and first of all, checked all the cables in the unit if they arecscrewed on oke....
Did you have the problem all of a sudden with the same gear( replaced large tv etc)

Hello,the most common solution is to simply replace the subwoofer cable itself. the ground on this cable is the outside of the connector and not the pin in the center and they do fail. You can use any rca cable as a quick test to confirm if the cable is at fault.

The amp on my kef sub woofer amp is making a consent buzzing noise it sounds like a kettle boiling. Help


Ok so no guarantees this will work, but it did for me and I knows it's very late but hopefully it will help someone else with a similar problem.

I had the same problem and as clmrt5000 said a very long time ago there could be an issue with a ground loop, although this is likely to give a high pitched buzzing sound.

This can easily be fixed by adding a switch to disconnect the mains earth from the back plate, or you can just unscrew the earth and tape it up, this fixed my ground loop, (some models already have a ground lift switch)

As for the "boiling" sound I also got a saw tooth wave sound (like a strange squeak or beep that changed frequency) this is caused by faulty components, and thanks to Frank Johnson (http://lug.demon.co.uk/kefrepair/?p=60) who suggested that you can simply and easily replace 3 capacitors on the main amplifier board (c58 - 47uF 63v or 100v) + (c52 & c53 - 220uF 25v) but stand them away from the board on the length of the capacitor leads to prevent them from absorbing heat from surrounding hot components (with heat shrink tubing to prevent shorting)

Now my sub works as good as new, apparently these 3 capacitors can cause all kinds of problems it's a common fault, so if you are handy with a soldering iron, or know someone who is you could save yourself a lot of money by repairing you faulty KEF sub.

p.s. if you have ANY of the KEF PSW subwoofers they all have similar issues, you can find a guide to fixing them at the link above, Frank is a brilliant and very helpful man.

you have a ground loop issue you could purchase a ground loop isolator, jensen makes them for about 40 bucks.I have discovered that if you have cable tv, unplug the incoming cable in your cable box and see if hum disappears.

Hi, I get a buzzing sound coming from my s8.3 when it's plugged into the power outlet. No other cable are connected, it's only plugged into power outlet. Any suggestions? thank you!


I also had a severe hum or buzz that was NOT a ground fault loop issue or any other such problem.

Hummed to the point that reading in the family room was annoying !

I took my amp to a Very Qualified shop and the technician simply insulated the transformer 40.00 usd

I have curtis htib 1000 and it make a buzzing and humming sound and i wanted if someone can repair it for me


There are a few things that can cause this but two in particular are the most common. One is a ground loop. If you have multiple pcs of equipment hooked up a ground loop can be created. Ground loops are basically different grounds that are not held at the same potential. The second could be a power supply filter cap is going bad or possibly not in the circuit. Capacitors filter out the 60Hz noise after the AC is rectified. Any 60 hz getting into your amp will cause it to hum.

My home theater speakers make a constant hum whenever my receiver is on. The loudness of the hum changes with the volume control, and goes away entirely when the system is muted. All components are plugged...


jd40,
Sounds like a grounding issue. The first two places to look into is the powered subwoofer and antenna. During your last test, did you leave the FM antenna and subwoofer connected? Many times the hum is directly related to the antenna and/or the subwoofer and to how they are grounded; creating a ground loop through the receivers ground on the outlet. If the antenna is grounded to the dwellings wiring, hum is inevitable and sometime you can get a ground loop hum from how or how & where the subwoofer is grounded. Try taking them completely out of the loop.

Also try taking it further back to the basics, start with the receiver plugged into a known good grounded outlet with no surge or line conditioner in the loop and nothing connected to the receiver, nothing. Use one speaker and different wire to test each speaker output while in tuner and any other mode but phono. With no signal, you will either get nothing (no hum or static) or just static in the tuner mode. No hum is a good sign. Some systems will mute the speakers if no signal is connected to eliminate the static from being produced through the speakers but a ground loop hum will most likely still be produced even in mute. If you get a hum when nothing is connected to the receiver, try looking into getting a better grounded outlet, even maybe to a different dwelling.

This is the bane of all home theater installations and its called the "60 Hertz Hum" Most likely coming from your cable company.. Simple test... Disconnect any Coax cables from the outside going into your cable box or tv. Hum disappears. Most likely this is caused by a "ground loop" problem.

The solutions are far and varied. Google "ground loop hum" to find different things to try

I'm getting electrical humming from my crossover and i know its not the amps because i put the RCA's strait to the amps and it didn't hum.


If it only hums when the engine of the car is running, it is engine noise, usually caused by a ground loop. This happens when you have car electronics grounded at different points in the car, but connected with RCA's. Most car audio shops sell what is called a ground loop isolator that you put inbetween the rca's and the amp to take care of the noise.

Humming noise.....


Try to isolate the grounds of the amp and that of your head unit. I mean 'lift' the ground connection. Just connect the hot side and not the ground wire - your amp's grounding and your head unit's grounding might have a voltage loop. smile when the hum dissappears.
