SOURCE: I use an azur intregrated amp 540A and a Azur Pre

I've never repaired one of these but I have an amp at home that makes a intermittent static "popping" noise that i'm going to put down to a dirty volume pot (control) that needs cleaning. I will also have to change some of the electro capacitors that have dried up inside which cause "shot noise". With the right lubricant (electrical contact cleaner, nothing else) you could take to lid off and spray a small 1 second blast into the hole of the pot and any other balance or tone control yourself but I would take it to the electronics repairer to get the capacitors checked over.
My theory only
Good Luck!

Hello
There is some loose solderings or leaky ceramic capacitors at the audio output section of your sound card. Check it.

SOURCE: Sub Speaker giving intermittent loud crackling and sharp loud popping sounds even with main volume control turned off. Crackling sound can be reduced by turning sub volume control off.

It may be the control itself too. In time, these controls can get dust build up inside it. There are volume control spray cleaners available from Radio Shack or other electronic parts stores. The cheat on cleaning the control is to just rotate it from stop to stop as many times as it takes to clear the noise.

My amp turns on good but after a while of too much bass causes a ugly sound too loud what could it be? Can it be repaired?


If you have over driven the amp by playing it real loud with the bass control turned up, it is very possible that you have toasted the output stages of amp.
Every time you boost a tone control by 3 db you have doubled the output power at that frequency. So if you are "coasting" along at a nominal 75 watts, the moment you boost the bass by 3 db the amp has to put out 150 watts at that low frequency.. Go to +6db and now the poor amp has to kick out 300 watts! And so on.

Rule of thumb - you never use your tone controls at very loud levels. Tone controls are there to compensate for the poor frequency response of the human ear at low volume levels - the Fletcher Munsen effect. At low volumes our hearing with the lows and high frequencies so when you play something at low volume you boost up the bass and treble to compensate for poor hearing. At loud volumes our ears respond properly.

My Technics SUV 660 is making a crackling and popping sound regardless of where the volume is. It does reduce once the amp has been on for an hr or so. Also the speakers are not consistantly on. Any a


If the sound is on both channels then it's probably a device that is connected to both channels. I don't think it's the power supply. I rather suspect it's in the power amp section, since it's not affected by turning up the volume. If the amp uses one of those STK devices as a power amp, it could even be that.

What is wrong with my Samsung HLS42WX/XAA everytime I turn it on after ten minutes the volume start making a loud crackling sound then there is no volume sound at all. What do I need to do to get this


It clearly may be a sound problem in the set but a few things you might check, First of course is do you have this issue on all inputs including the rear ones, does a DVD player connected to a rear input do this or not?

If you have a box connected to this set unplug both the box and set from power for a while, cannot hurt but may help.

If using a box and set does not do this with a DVD it may be possible to get around the problem.

A box or even the tuner in the set may be the cause==your tuner not only processes regular signal but also develops the sound signal, it may be bad.

My mackie thump amp will start to have a loud cracking sound. The cracking goes away if I have the input line unplugged from the speaker but with it plugged in it has the cracking sound and it does not...


Crackling is usally one or two things my guess would be bad grounding of the amp or bad connection with the jacks or plug it self try to make it crackle on purpose by jiggling the jacks see if it has any effect on the crackling try to narrow your possibilitys

Popping noise while computer is powering down. Any suggestions?


Hi,
Lower your main sound volume. Double click the speaker icon in the bottom right hand corner of your windows.(was it maxed out?)

go into control panel /sounds and select a lower bass setting in your sound settings. You usually have a choice of rock & roll ( lots of bass) opera setting, classical etc.. choose one with less bass.

Make sure your LINE IN is DISABLED. It may be causing this static feedback.

You may have blown your speakers by playing sound way too loud. You may need to buy new speakers.

Thank you and Good luck. *s*
