How does volume knob work?
The knob is a rotary pulse generator. Most produce to digital signals which look like two square waves with a 90 degree phase difference. The electronics that run your radio can tell which way the knob is being turned by the sequence of transitions of the two signals.

- Whether the knob turns to the minimum or maximum or any section in the middle, the speaker sound is normal when the maximum volume.
- Knob to the minimum or maximum, the sound is slightly smaller; knob to the middle of any section, the sound is slightly louder, and the sound quality is not good.
- Exclude the knob potentiometer failure, use a multimeter to measure the potentiometer resistance, found that the change can occur with the rotation of the knob.
Repair method
- If the potentiometer fault has been ruled out, the signal should be a short circuit to ground, simply put, is the amplifier board potentiometer ground end of the copper foil break, directly causing the signal can not be shorted to ground.
- Need to detect the ground terminal, and then repair the location of the fracture, so that the audio repair normal operation state.
Speaker sound knob can not adjust the volume of the speaker sound knob failure:
- Computer speakers over time, highly sensitive components are prone to problems, especially the volume adjustment knob, once the problem occurs, it will make the left and right speaker volume jump, the volume size can not be consistent, so that one side of the speaker is very loud, one side of the sound is not.
- The problem may be too frequent volume adjustment or speakers placed indoors for a long time, the electronics are aging or moisture, resulting in sensitivity problems.
Repair method
The most effective way is to buy a new stereo, sell the old one; or repair the volume adjustment knob, but the use of time is not long, there will be such a problem.
Speaker sound knob can not adjust the volume, is generally adjusted too many times, it appears damaged, if the problem is not large, can be repaired well, but the use of limited time, it is best to adjust the volume less.
