Why do my speakers pop when I turn on the amp?
To eliminate the DC, designers put a capacitor between the amplifier output and the speaker. When the power is turned on, that capacitor is not charged, and the amplifier’s output quickly goes from zero to 50 % of the supply voltage. The popping sound is caused by the capacitor pulling current through the speaker.
What causes an amp to clip when the volume is high?
Generally speaking, the amplifier gain is not properly set or the volume is too high. The most common, and avoidable, form of amplifier clipping occurs when an audio amplifier is driven beyond its ability to generate sufficient voltage or current to reproduce the original signal to your speakers.
What causes an amplifier to make a popping sound?
Many amps have “protection relays” that keep the speakers disconnected for a few seconds when the amplifier is first switched on, to allow all of the circuitry to stabilize and minimize such an occurrence; those that don’t will “pop” when they’re powered up.
Why do my speakers pop when I turn the volume up?
Click to expand… In the old days, back in the 8track era, the stereos had felt with slits cut into it that the shaft or slider would stick through to protect dust from getting into the pots. Now they just stick a plastic knob on the shaft and hope for the best.
Why does my amp shut off after certain volume?
No rush, its not urgent, thanks! An amp can shut down when it detects clipping distortion caused by its reaching it’s power output limit. This can damage tweeters so a protection circuit can be designed to operate quickly. It can be caused by a bad driver or crossover part in the speaker system or an “almost short” in a speaker wire.
Why does my JBL speaker pop when I turn it off?
If the pop begins to bother you – and the possibility of even a short burst of DC through the voice coil should, you could add a high wattage potential switch to the speaker line and simply switch the speaker feed out before shutting down the amp. You’ve got a 200 watt amp and JBL’s, Mark.
Why do my speakers pop when I Turn Up the volume?
So my problem is that i have the mid speakers popping or crackling at high volume. Sounds as if the cone is over extended, that kind of popping sound. When i turn down the volume a little it goes away. But if i turn up volume they pop on some songs but not all songs.
What to do if your amplifier makes a popping sound?
A good cleaning and vacuuming will usually take care of it; (just be sure you unplug the power and let the amp sit for an hour or two so that all of the power supply capacitors are fully discharged before you go opening the lid!)
