Troubleshooting & FAQs

Amplifier board has current sound and noise during use

Most amplifier boards using DC power supply do not produce current sound and noise. Main causes:

Poor power supply filtering or incorrect power/audio input
Poor input signal quality or abnormal audio source input
Poor quality input cables, poor connections, damaged wiring, or suspended wiring
Other playback devices in input connection or shared power supply causing noise

No sound output or no sound in one channel

Speaker damage or poor speaker cable connection
Poor input cable connection, damaged wiring, or improper output from connected device

Volume broken and breaking sound when turned loud

Insufficient power input - confirm correct wiring and adequate supply current
Poor speaker performance or damage, speaker power too small or too large
Left and right channel speakers (+) (-) outputs are independent and cannot be connected to each other

Speaker broken sound when subwoofer amplifier volume turned loud

Insufficient power input - confirm correct wiring and adequate supply current
Speaker power too large or too small, poor bass performance, or speaker box structure abnormalities

Volume power not enough

Power is related to power supply voltage, sound source signal amplitude, and speaker impedance size. Any deficiency will affect power output.

Will the amplifier be burnt?

Power supply positive/negative poles connected reversely
Power supply voltage too high, exceeding board's limit operating voltage
Connecting AC transformer power supply directly (must be rectified to DC first)
Incorrect wiring or short circuits causing damage to key components
