Elevating loud noise and pop

Got this new about one year ago and recently it will start this hissing noise-floor type of sound through the speaker that eleveates in volume until it pops real loud (and then it's done). I unplugged the pedal switch and the speaker input, but it still does it. It happens randomly, and will repeat, making it unreliable for gigs. thanks for the help!

Hi melissa961

Not sure what make and model your rig is but the symptoms you have are classic for a failing transistor or capacitor. There is not a lot you can do about this except trace down the faulty part and replace it. We do this in the workshop by cyclic heating with a heat gun, and cooling of individual components with freeze spray until we locate the offending part. If it is a year old, I am hoping that it had a 1 year warranty, and that you are close enough to the end of it that you can claim the repairs as warranty. Sorry that this does not actually fix the problem for you, but now you know what you have to do next. Get the amp back to the retailer you purchased it from. Hope it all works out for you. If my advice has helped to resolve the problem for you, a FixYa rating from you would be great. Cheers

regards

Speakers have hissing noise coming out of them


Hook a graphic equalizer between the piano and speakers, and turn down all sliders above 8 kHz. Since the highest note of a piano is 4186 Hz (4.186 kHz), you'll still hear all the notes but cut the hiss. If the hiss is coming from the speaker's power amplifier (in which case the equalizer won't help), turn down the speaker volume and turn up the piano volume. Live instruments generally need some doctoring to sound good through high-quality stereo equipment, as they only produce a limited range of frequencies whereas good speakers reproduce a lot more - including hiss.

Guitar amp make large crescendo-like noise, loud pop at end.


Same loudness, no speaker? This sounds (no pun intended) like a filter capacitor shorting out. Open it up and VERY CAUTIOUSLY look for what is making the noise. Filter capacitors can eject hot stuff. Very dangerous.

Logitech x530 hissing noise


I had the same problem for the longest time with my set of Logitech 540 5.1 speakers. Turns out the solution was pretty simple. All I did was open the Master Volume controller and mute the Microphone. Hissing went to zero. Sound is great now.

Overloading


hi mate, ive had the same problem before with this amp. i bought it new aout 6 years ago and bought another new one about 1 year ago, new, for £70!

on the first amp there was a problem with the surround sound aspect, it kept overloading when turned up even a fraction, it would tick 4 times and power off. Eventually the surround sound stopped working all together and whenever selected made a VERY VERY loud hissing/crashing noise through all my speakers, blowing one of them, SO BE VERY CAREFULL.

when that happened i assumed was broken so bought another one, and had same overload trouble when i got a new speaker package.

Im pretty dam sure it was the ohmage ratings being different on 2 of the surround sound speakers that srewed the 1st one, so id suggest you check theyre all ok, as well as the speaker watt-age.

what are the specs on all your speakers (ohms and watts RMS)??

do you listen to LOUD music through the 5.1 option??

hope this helps, if all else fails buy a new one mate, theyre so cheap. go into panasonic shops and see if they have any left.

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.
