JVC RX558 VBK, Crackling noise from speakers

There is a crackling noise from the speakers when the receiver is on, at a medium volume level. Speakers B are not longer functioning.The noise is present while playing CD, TUNER, VCR or DVD sources.The speaker connections have been checked.There are 2 front and two rear speakers plus a sub woofer, connected to this unit.Sometimes the display announces OVERLOAD, that is corrected by turning off the unit.What is the cause or source of this crackling noise? Thank you for your time.

A quick quess of mine is the following:

The OVERLOAD indicator lights up when the receiver is maxing out on the current it is sending to the speakers. My guess is there is possibly something wrong with the receiver itself, especially since the B speakers won't play. Either that, or something is broken in your speakers or you are using a set of speakers that have too low an impedance rating for your receiver.

Panasonic sa-pt860 speakers crackling


Panasonic SC PT860 Manuals
The above link is the owner's manual - it may help.
Here are some other ideas:
Try to find out if the crackling sound is coming from all speakers or just one - you may just have one bad speaker.
If the crackling happens at high volume settings, you may be overdriving the system - you'll just have to turn it down!
Try turning down the bass or the subwoofer level.
Is the crackling present with all sources (TV, cable, DVD, bluetooth)?

When i turn the volume up to(17-20) my sound cuts out and my speakers make a cracklin noise.i have bought new speakers and rechecked all wires.my speakers are rated at 50 watts rms and my stereo pumps out...


It seems you needs more power to maintain the level of good sound.Maybe the maximum volume is 30 - then the mininum is 15 and you can't hear any cracking sound. If you exceed 15 the minimum, as you said starting 17 - 20 you hear crackling sound .Then you reach ,what they called the "cliping level"so much distortion and crackling sound,your stereo too small to accomodate .You must add a power amplifier so crackling will gone and to fit your listening pressure...

Hope it may help you;

Keeps blowing speakers on left front channel


What exactly do you mean by "middle volume settings"? Where is the volume control physically, where are the channel levels set and what is the crossover point? After the crackling appears , do you switch speakers to the right channel to see if speakers are actually damaged or if the receiver is producing the distortion?

I have been experiencing static noise/crackling from my front left and right speakers just recently. (I have a 5.1 dell system - the front center - attached to the monitor and rear speakers do not emit...


This seems like at cables have gone bad or either the connections in the speakers went bad. Its best to replace them unless you know how to disassemble and re-soder the connections.

My Korg c15s has a lot of grating staticky noises when played ....I'm told it cannot be repaired as Korg no longer makes parts for this model?


I have a Korg C-15s and also experiencing loud crackling sounds when I turn it on. The problems seems to be either the sliding volume control or the amplifier itself. Honestly though, I believe the issue is the volume control. I opened my piano to get a closer look and attempted to clean the contacts on the volume. Unfortunately after cleaning the contacts, the crackling sounds became somewhat worse. After I turn the piano on, the volume control is generally rendered useless......volume set to low volume and the noise is quite loud and other times the volume control is set high and get very low volume crackling noise. No real consistency. The noise does diminish after a few minutes but so does the piano sounds to an inaudible level. There were a couple of instances where I turned it on and surprising enough, no no noise and perfect sound. For these reasons I believe the issue is within the volume control and not so much the amplifier. I have an electronics background and noticed that the volume control is very unique in design and is not something that can be substituted with another volume control from other sources.

My recommendation is to check the sound quality of the audio from the RCA L/R audio outs on rear of the piano by connecting to a stereo receiver. If it sounds fine you're in luck. If the crackling sound does not diminish after a few minutes like mine does, I would suggest disconnecting the internal speakers and using the audio out only. You can connect a pair of studio monitors or high quality computer speakers, preferably with a small subwoofer to deliver the full audio range and deeper tone of a real piano. I'm currently using a basic pair of Logitech computer speakers and is quite acceptable until I can afford a high quality set of monitors or relocate my piano closer to my high quality Yamaha receiver.

I hope this info helps a bit.

On my jvc 517v when you turn the volume up the speakers are crackeling and scratchie and speakers sound terrible.


Is this a NEW problem or has it always been like this? What modes or sources are affected? Generally, crackling, scratchty sound is either overdrive distortion, speakers being pushed too hard, or blown speakers.

What is the exact model. Can't find the manual for "517v".

Sherwood Rx4050r and right speaker has crackling noises.


Ahh, that channel is blown. Its not 100% blown. This has happened to my freind before, and from my long knowlage in audio, the channel is blown, and is not fixable. If you REALLY are attached to it, you could probably bring it to a shop that fixes receivers, but best bet is to let it go

On my Sony Surround Sound tuner, if I raise the volume up to a certain level (not that loud), I get a flashing sign ''protect'' and the sound to the speakers are cut.


Sony has protection in these receivers for two main reasons.

1 - Checking for DC voltages on the outputs to speakers. Not your particular problem.

2 - Excessive current being drawn from receiver on one or more of the speakers.

Number 2 should be your starting point in finding a solution. Put the volume level on Medium - 35 to 40 on the front panel. Now listen to all you speakers in turn. Any scratching noise will indicate a defective speaker. Remove this speaker from the receiver output and check again if the set goes into protection on high volume.

If you could not find any strange noises on the speakers, remove them one by one and test the set on high volume.

Never - attempt to disengage the protection on this amplifier. The only times we have found the amplifier to be defective with this protection error, it has done so no matter the volume level. Therefore I believe your problem to be a speaker or speakers.

Good luck!

There is crackling coming from the horn as soon as the power is turned on, the level of the crackle does not alter with the volume control, the cabinet performs fine otherwise ?????


The horn speaker is wearing out. Inside speakers, there is a magnet, the speaker part is attached to a cone that slides over the magnet, They tend to make crackling noises. Try very gently to apply pressure to the horn and then release. If you hear a scratching sound, the horn will need to be replaced
