Question about Audio Players & Recorders

2 Answers

When I turn my receiver on it makes loud popping noises from speakers. I repeat turning it off and on until it doesn't have the popping noises and then everything runs normal.

This was happening last Spring and stopped during the Summer. Now that it is Fall it is doing it again. I had the people who put this stuff in come out and they had no answers, just told me I need to replace it.

Its likely a dirty contact on safety relays or volume track.
Remove power and rotate volume min to max 5or 6 times.
Or it needs safety relay contacts cleaning/repairing or ensure the volume is turned to bottom before you end up popping a cone on your speakers.

It's your output relays. They prevent the inrush current at power up from reaching the speakers so no damage to them will happen. The relay contacts wear or stop working altogether so replacing them is the fix. The reason you don't hear the pop after repeated on/off cycles is because the inrush current has dissipated. That tells me the relays are the problem.

10 years and first problem to repair. When you turn on and select DVD or any other selection a very loud cracking noise comes through right speaker only. So loud (with volume tuned off too) that I fear...


I think your receiver is damaged.

Try this.

Mark the speaker wires on the back of the receiver. label the speaker connected to the left channel "Left" and the speaker connected the the right channel "Right"

Also pay attention to the polarity (positive an negative) making some type of marking on your speaker wire so you can reconnect them correctly.

Disconnect both left and right speakers.

Connect the speaker wire that is labeled "Right" to the receiver's left speaker connections only then turn your receiver on.

IF the loud noise comes back, this speaker is damaged. I am guessing that the speaker is fine.

Now connect the speaker that was labeled "Left" to the receiver's right speaker connections and turn the receiver on.

IF the loud noise comes back like it did before but now playing through the "good" speaker there is a problem with your receiver.

If so, your receiver is 10 years old. Isn't it time for an upgrade? Try ebay for good used equipment deals.

I have a saex700 with mission speakers 753x4 connected when i run all 4 of them fairly loud i seem to get a sort of popping noise from the speakers if i turn 1 pair off it stoppes its not the speaker


Transient response is increased with all four speakers connected so you are hearing cone rattle that you wouldn't hear ordinarily. Excessive drive is a contributing factor as well.

Popping noise


Check the sub with a multimeter. It should read the ohms it is rated at when you hook it to the positive & negative inputs. It its off your coil if bad.

JBL PB12 will have loud thump or pop!


First try to find the source of your problem. The easiest way would be to try your sub with a different audio source to see if the problem still occurs but is sounds more like there's a problem with the receiver.

Loud repeating noise until the water trigger is pressed


Check the pressure washer for leaks. That sound is probably the unloader valve recycling as the machine slowly looses pressure and needs to build it up again to max pressure.

Static noise from Front Left Speaker


It would probably be with the speaker. That is easily checked by simply unhooking the speaker and running the test again.

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.
