Poor power supply filtering: Hum may result from abnormal power supply or audio input.2. Poor input signal quality; abnormal noise from connected playback device output indicates faulty audio input.3. Low-quality input cables; poor cable contact; damaged wiring; loose connections.Q: No sound, or one channel is silent.A: 1. Speaker cables are disconnected.2. Poor input cable contact; damaged wiring.Q: Volume distortion or clipping when turned upA: 1. Verify correct wiring and sufficient power supply current. Poor speaker performance/damage, or mismatched speaker power rating.2. Left/right speaker outputs (+/-) are independent and must not be connected together.Q: Can the amplifier burn out?Answer: 1. Reversed power polarity; excessive power supply voltage; exceeding operating limits.2. Ensure correct wiring before powering on; incorrect connections cause short circuits.Question: Insufficient volume/power outputAnswer: Power output depends on power supply voltage, audio signal amplitude, and speaker impedance. Any deficiency affects power delivery.Q: Subwoofer distorts at high volume.A: Insufficient power supply. First verify correct wiring and adequate power supply current. Other causes include:- Speaker power rating too low or too high- Poor bass performance of the speaker itself- Subwoofer enclosure designAny of these issues can cause distortion.Package Contents:Digital Amplifier Board*1
