Do your speakers explode when you change the volume? This problem usually only occurs when you increase or decrease the volume. The speakers sound good when the volume control stays in place. In this article, we will show you how to troubleshoot and fix this problem.

Crackling speakers when changing volume can be caused by a dirty connection in the volume control or potentiometer. It could also be due to dust or flakes in the volume container. A quick and easy solution is to spray a cleaner and gently turn the pan to clean it.

However, if the trace is damaged, even a spray cleaner won't help and you'll have to replace the tray.

Quick fixes for speaker crackle when changing volume

Here are some quick fixes for this problem:

  1. Contact cleaner:Spray a cleaning agent such asdeoxygenatethrough the holes in the body of the pot and slowly turn it from side to side. It's easy, just turn the amp off, open the lid, and spray some onto the button assembly. Don't twist it violently or you risk damaging the trace.
  2. WD40:If you don't have a suitable cleaner, you can use WD40. with WD40 you can do it again several times after a few hours. Also, wait a few days before turning on the amplifier.
  3. Pure alcohol solution:You don't need any special liquid if you don't need it. Any pure alcohol would do an effective cleaning. You can even use an aftershave.
  4. Compressed air:Using compressed air to blow out the pan is an easy way to remove dust while turning the pan clockwise and counterclockwise. However, this may not work if dust gets trapped in the tray.

Let's dive into this problem and how to fix it.

By the way, if what you hear is static and not crackling, read our article onhow to stop static on speakers.

What makes the speakers crackle when the volume is changed?

The speakers often crackle, especially when you try to change the volume but something interrupts the power.

Remember, speakers are simpleelectrical converters🇧🇷 They convert audio signals in the form of electrical energy into sound. Sound signals are electrical signals with alternating current. The signal generates aCrackling or crackling sound from the speakerwhen interrupted.

(Video) How to fix a crackling sound when you adjust the volume knob on your sound system.

But what do crackling speakers mean?

Loudspeakers respond to audio signals by moving linearly and with a magnitude that corresponds to the signal being applied.

When an alternating current carrying the audio signal flows through the speaker, the speaker drivers move in and out. The speaker then reproduces the sound waves. This is done through the speaker membrane.

When the signal alternates, it has maximums and minimums in the cases where the signal has peaks.

When the signal reaches maximum positive voltage, the speaker driver is pushed to the maximum position it will reach during that cycle.

When the signal reaches the minimum or maximum negative voltage, the speaker driver is pushed to the innermost position it reaches during that cycle.

This type of oscillating movement is repeated when the speaker receives audio signals in the form of electrical waves.

This type of motion is similar to the sine wave signal driving the speaker. However, when this pure sine wave signal is interrupted, a crackle is heard.

To properly understand crackle, consider a simple peak and trough sine wave signal. The sine wave is a good representation of a single frequency audio signal. A horizontal line through the center of the wave represents zero voltage.

Like alternating current, it reaches a maximum positive voltage when the signal peaks during a direct current flow.

On the other hand, the maximum negative voltage is reached when the signal bottoms out during reverse current flow. The sine wave also represents the movement of the speaker.

As you can imagine, the movement of the speakers is as smooth as the sine wave. This allows the speaker to produce smoother sound without interruptions.

This continues as the current carrying the sound signal flows through it. Therefore, no crackle occurs during this time until the current in the signal is interrupted.

crackle and sine wave

When the audio signal carrying power to the speaker stops, the sine wave also stops.

Therefore, the sine wave is no longer smooth and represents intermittent motion in which the speaker tries to appear in two different places at the same time.

That leads topops or clicks in audio output, a phenomenon commonly known as speaker cracking.

creaking E Osquare waves

This is more of a waveform, but instead of taking the shape of a regular wave, it looks more like a square. Because normal sine waves experience more distortion and discontinuity, they are more like square waves.

When a speaker experiences a perfect square wave, the sound distortion will be terrible.

Abrupt signal transitions from maximum positive to maximum negative voltage that occur on each cycle cause inherent crackle in the speaker.

However, there is an abrupt transition between maximum and minimum voltage, so the speaker vibrates more linearly without striving to appear in two places at once.

Is this a clipping issue?

No, it's not a clipping issue if the crackle only occurs when you adjust the volume. The cut is different.

Clipping is an electrical problem that occurs when the output signal reaches its maximum level and tries to exceed it, and the signal appears distorted and "clipped". Sometimes cutting is the cause ofregular crackles and pops.

Why does my speaker crackle when I change the volume?

As we mentioned earlier, speaker crackle is caused by an electrical interruption that results in an interruption in the passage of the audio signal.

For any audio device, changing the volume means changing the strength of the electrical signal going through it. Since this signal contains the audio signal, as the electrical intensity changes, so does the pitch.

Is vinyl crackling to blame?

The crackle of the speaker and the crackle of the vinyl are two different things. The power outage causes the speaker to crackle.

Vinyl crackle, on the other hand, is caused by dust and static electricity. When this happens, the vinyl picks up static electricity, some of which is picked up by the speaker as noise.

Can I fix the crackle in the speaker? What?

Speaker popping can be fixed, and we actually have onecomplete guide on how to fix speaker pops and pops🇧🇷 Follow the procedure below to fix the problem.

  • If you feel a crackle from the speaker, turn off the stereo receiver first.
  • Once the stereo is off, check the speaker cables to make sure they are properly connected to the stereo receiver and to the speakers.
  • Nearby electronic devices are more likely to interfere with the audio output from the speakers. turn them off
  • If the speaker wires are close to other electrical wires, move them away from the wires.
  • Reconnect the speaker to the stereo receiver and see if the issue is resolved. If the click does not go away, follow the instructions in the receiver's manual to factory reset the receiver.
  • If all attempts fail to resolve the issue, replace the speaker wires and try again.
  • Use a vinyl brush to remove dust from the speaker to resolve the issue if it is related to vinyl crackling.
  • If the cracking continues, try replacing the speaker with a different one or a new one. If the cracking goes away, it's clear that the speaker was the cause of the cracking. However, if the problem persists with the newly connected speaker, then the receiver is the source of the problem.

Why is my speaker crackling?

It is advisable to first check that it is not a connection problem. A damaged or bent cable connection can cause interference and distortion in the audio.

This happens when the amplifier does not deliver enough power to the speakers. The higher the power produced by the amplifier, the louder the sound produced by the speaker and the better the sound.

Is crackling bad for speakers?

Audio crackle and distortion can damage your speaker, so it's best to fix these issues as soon as you notice them. Continued use can make the problem worse and there is little protection circuitry available to reduce the effect if you continue to use it.

Are digital clicks similar to speaker pops?

Digital clicks occur when a digital audio signal stops abruptly. When this happens, the signal suddenly drops from a certain amplitude to zero.

The effect appears like a power interruption, especially when the signal goes through a digital-to-analog converter.

Infinite Impedance

Set the meter to ohms, make sure the speaker is turned off, and touch the lead of the multimeter to the speaker terminals. A multi-meter reading of 1.0 ohms means the speaker is not blown, but a reading of infinite ohms means it is blown. A completely blown speaker will have infinite impedance.

How do you test speakers for damage? ›
