Frequently Asked Questions:
Q: Amplifier board use current sound, noise?
A: Most of the products are powered by DC power supply, which does not produce current sound and noise.
1. Matching power supply filtering is not good current sound is the power supply or sound source input is not normal lead to
2. Poor quality of the input signal; the output of the device connected to the input playback is not normal noise is caused by the abnormal input of the audio source.
3. Poor quality of the input connection line; poor contact with the line; wiring damage; wiring overhang

3. Poor quality of the input connection line; poor contact with the line; wiring damage; wiring overhang
Q: no sound, a channel no sound
A: 1. Speaker connection line is not through
2. Poor contact with the input connection line; wiring damage
A: 1. Speaker connection line is not through
2. Poor contact with the input connection line; wiring damage
Q：Volume up, broken sound, broken sound
A: 1. First confirm whether the wiring is correct, whether the power supply current is sufficient B, poor performance or damage to the speaker itself, the speaker power is too small or too large
2. Left and right channel speaker (+) (-) output is independent, can not be connected to each other!
A: 1. First confirm whether the wiring is correct, whether the power supply current is sufficient B, poor performance or damage to the speaker itself, the speaker power is too small or too large
2. Left and right channel speaker (+) (-) output is independent, can not be connected to each other!
Q: Will the amplifier burn
A: 1 power supply positive and negative poles are reversed; power supply voltage is too high; beyond the working limit
2. Wiring should be correct, and then connected to the power supply, connect the wrong line will lead to a short circuit
A: 1 power supply positive and negative poles are reversed; power supply voltage is too high; beyond the working limit
2. Wiring should be correct, and then connected to the power supply, connect the wrong line will lead to a short circuit
Q: Volume power is not enough
A: Power and power supply voltage, the amplitude of the audio signal size, speaker impedance size are related to any kind of insufficient will affect the power
A: Power and power supply voltage, the amplitude of the audio signal size, speaker impedance size are related to any kind of insufficient will affect the power
Q: subwoofer amplifier volume up after the speaker broken sound
A: Insufficient power supply, first confirm that the wiring is correct, whether the power supply current is sufficient whether the power of the speaker itself is too small or too large, the speaker itself is poor bass performance, the structure of the speaker box, these abnormalities will lead to sound breaking!
