Installation Tips

For best results:

  • Mount on metal chassis for heat dissipation
  • Keep input wires away from power wiring
  • Use shielded cable for audio inputs
  • Add 0.1µF capacitor on power input
Apply thermal paste for better heat transfer
Twist speaker wires to reduce noise
Do not operate without heatsink
Keep ventilation holes clear

Troubleshooting

No sound output:

  • Check power supply voltage
  • Verify input signal present
  • Avoid speaker impedance too low

Distortion:

  • Reduce volume level
  • Check power supply capability
  • Avoid clipping at high output
