Frequently asked questions:
Q: Is there current sound or noise when using the power amplifier board?
Answer: Most of the products are powered by DC power, which does not generate current sound or noise
1. Poor filtering of the power supply used, current sound caused by abnormal input of the power or sound source
2. Poor input signal quality; The abnormal output noise of the device connected to the playback input is caused by the abnormal input of the sound source
3. Poor quality of input connecting wires; Poor wire contact; Damaged wiring; Wiring suspended
Q: No sound, one channel is silent
Answer: 1. The horn connection line is not connected
2. Poor contact of input connecting wire; Damaged wiring
Q: Turn up the volume, break or break the sound
Answer: 1. First confirm whether the wiring is correct, whether the power supply current is sufficient, whether the horn itself has poor performance or damage, and whether the horn power is too low or too high
2. The left and right speaker (+) (-) outputs are independent and cannot be connected to each other
Q: Does the amplifier burn
Answer: 1. The positive and negative poles of the power supply are reversed; The power supply voltage is too high; Exceeding working limits
2. The wiring should be correct, and then the power supply should be connected. Connecting the wrong wire can cause a short circuit
Question: Insufficient volume and power
Answer: Power is related to power supply voltage, amplitude of sound source signal, and horn impedance. Any deficiency will affect power
Question: When the volume of the subwoofer amplifier is turned up, the speaker breaks
Answer: If the power supply is insufficient, first confirm whether the wiring is correct, whether the power supply current is sufficient, whether the power of the speaker itself is too small or too large, whether the bass performance of the speaker itself is poor, and the structure of the speaker box, all of these abnormalities can cause sound damage
