Maintenance
General Care
- Regularly inspect all wiring and connections for signs of wear, corrosion, or damage.
- Keep the amplifier clean and free from dust and debris. Use a soft, dry cloth for cleaning. Avoid harsh chemicals or abrasive cleaners.
- Ensure adequate ventilation around the amplifier to prevent overheating.
Water Resistance
The amplifier is designed with IPX7 water resistance, meaning it can withstand incidental exposure to water. However, it is not intended for prolonged submersion. Always ensure all covers and connections are properly sealed.
Troubleshooting
No Audio Output
- Verify that the amplifier is receiving power and its indicator light is on.
- Check all audio connections between the amplifier, stereo, and speakers.
- Ensure the connected Fusion DSP-enabled stereo is powered on and configured correctly for the amplifier.
- Confirm that the volume levels on both the stereo and any connected devices are not muted or set too low.
Distorted Sound
- Check for loose or corroded speaker wire connections.
- Ensure the input signal from the stereo is not overdriven. Adjust the stereo's output level if necessary.
- Verify that the Easy Tune feature is properly configured via the Fusion-Link app.
Amplifier Overheating
- Ensure the amplifier has adequate ventilation and is not installed in an enclosed space without airflow.
- Reduce the volume or check for speaker impedance issues that might be causing the amplifier to work harder than intended.
