Symptoms of DC Leakage from Amplifier to Speaker

When there is DC leakage from the amplifier to the speaker, you may experience a loud humming sound when the amplifier is in use. Additionally, you may notice the deformation of the speaker cone, either pushed out or pushed in, along with no sound coming out of the speaker.

It is crucial to address this issue promptly, as it can lead to damage to the speaker. In some cases, the amplifier and speaker may come into contact with the circuit and even cause a fire, posing a risk to your safety and the safety of those around you.

Causes of Amplifier DC Leakage to Speaker

Amplifier DC leakage to the speaker is mainly caused by the malfunction of certain components on the power board, such as capacitors or blown fuses. This results in DC leakage in the speaker line.

As a result, the DC current from the power circuit is pushed out to the speaker line, causing a loud humming sound and eventual deformation of the speaker cone.

I hope the above information has provided you with a better understanding of the causes, methods for checking, and effective solutions for addressing amplifier DC leakage to the speaker!
