What causes plop sound in amplifiers? Means turning ON/OFF discharges some noise signal through speakers. What is the root?
How can we avoid it? Or reduce it?

 

It can be casued by the mains being switched. Putting a small capacitor across the switch can help.
Also the amplifier simply powering up can make a pop until the voltages become stable.

 

Finding the exact answer requires a complete schematic, and then some communication.

 

Half-decent amplifiers use a relay that connects the speaker only when the amplifier is powered-up and is stable.

Yes. But how does switching of mains cause this noise?? I'm still not clear on that.

I don't want to find SOLUTION for a system. I need your knowledge on this topic. I figured solution to reduce it. By simply putting mute mechanism at pre-amp stage. Still don't know how & what causes that discharge in to speakers!
