Buzzing coming from speakers

We have cable and we're getting a buzzing noise when we access channels above 23. Some channels are louder than others. I think it might be the IF coil, but I don't know where it is or how to fix it. Can you help.

The "IF coil" is used for all channels, so if channel 5 is clear but 25 is not, the problem is not in the IF. If your IF coil was loose or bad, all channels would drift off and you would have no picture or sound. If you have the TV set to "SAP", some channels would have no sound at all, so I doubt that your settings are wrong. I suspect that the problem is with your cable signal, not your TV.

Noise, I get a buzzing noise out of my speakers when i hook up my interface with a jack cable any help ?


If the buzzing is louder or softer, directly relative to the volume level, it is signal interference.

99% of the time, when you get the buzzing or "air" sound, it's the cable. To give you an idea of how serious this is, each of my speakers has a Monster THX Ultra 1000 speaker wire running to it, which can cost roughly $100.00 each. This is for the sole purpose of eliminating that air noise or buzzing.

When running speaker cables or AV cables, you don't want them to run parallel to each other, unless they are several feet apart. If they have to cross paths, you want them to cross perfectly perpendicular to each other so as to minimize the amount of contact they may have.

Speaker wire should also be twisted copper (unless running fiber optic cable, which would be extremely rare). Many people try to use solid strand, but a lot of the signal is lost, even when well insulated.

If your speakers are close to anything electronic, try to move them away from the source, or move the source from the speakers.

If you have a GSM phone, the phone can cause distortion in your speakers as well, but with the newer phones, that only happens when it reverts to the older tower technology.

It could be the source of your sound input as well. If you have a bad connection at the source (assuming your computer?), or the source itself just isn't a very good quality, this can also cause that buzzing or air sound.

Hope this helps.

Arcam AVR200. Buzzing sounds in all 5.1 speakers. Gets louder as volume is turned up. Tried all sorts of different things - different power source, 1 speaker, different modes.


I had the same problem. I was told by a sales guy at a high end audio store that I should try using a 3-Prong To 2-Prong Adapter. I went and bought one. I plugged it in and no more buzzing.

you can find them at HomeDepot, Lowes or dollor store.11_25_2012_6_28_23_pm.jpg

I have a RH50 T amplifier, it had a bit of a bumpy car ride to band practise the other day and now when i play through it, it will make a permanent buzzing noise on the clean channel that gets 70% worse on...


You may have damaged the variable resistors (the volume controls), you can purchase replacements from a local Electronics store (if UK based try Tandy). Otherwise have you checked the speaker itself for damage? You may have split the speaker which will need to be replaced.

When I play a CD I get a buzzing sound. The sound starts as soon as I hit the play button (and before the CD is actually moving.) It gets louder once the CD starts playing. The sound is coming through...


Buzzing is usally AC line noise leaking into an un-shielded cable somewhere or a floating ground. If the AC plug is reversible, try that. Sometimes the buzz is from an attached device. Make sure all audio cables are plugged in tightly at each end and routed away from or at right angles to any power cords and away from other sources of strong magnetic fields like TV's. I've also seen variable track lights induce noise but it's usually minor.

I have a Boston Acoustics VR-500 Subwoofer with a problem. As soon as anything is plugged into the line level RCA jacks, the subwoofer produces a loud buzz/hum. I have tried connecting it to the subwoofer...


I'm thinking you have an open shield ground on the RCA input side. Connecting speaker inputs possibly restores the ground. Try connecting the high level inputs then disconnect the remote end of the cables (floating the grounds).

Then get out an ohmmeter and find that open circuitor or bad solder joint between RCA ground and real ground in the speaker's amplifier. Or.... if speaker ground kills the hum and you want to use RCA Line Level input to the sub, just connect one minus speaker output on your source amp to one minus on the sub's amp.

Humm coming from speakers - can't get cable to work


The RF input is the correct one for a cable signal. The other sources use the RCA and other ports which you can connect to other devices, like DVD or VCR players.

If the humm noise only happens when you're on the TV channel then it's likely just the station. Try changing the channel and see if that helps, and make sure the coax is screwed in all the way. Also make sure the other end, if connected to a VCR or other stuff, is tightly attached. If you share cable with many other people and the signal has snow (white spots on the TV), then you may need to buy an RF signal amplifier to reduce the noise.

Source changes the input (RCA versus coaxial versus component inputs), change the channel for different channels..
