7. Fehlerbehebung
Sollten Sie Probleme mit Ihrem amplifier module, refer to the following common problems and solutions:
| Problem | Mögliche Ursache | Lösung |
|---|---|---|
| Keine Tonausgabe | Falsche Stromversorgung Voltage; Loose speaker connections; Audio source issue; Module not powered on. | Überprüfen Sie die Eingabelautstärketage is within 5V-24V; Check speaker wiring and polarity; Ensure audio source is playing and connected correctly; Turn the volume knob clockwise to power on. |
| Verzerrter Ton | Lautstärke zu hoch; Fehlanpassung der Lautsprecherimpedanz; Fehlerhafte Audioquelle. | Reduce volume; Ensure speakers are 4Ω-8Ω; Test with a different audio source. |
| Modul schaltet sich nicht ein | No power supply; Power supply polarity reversed; Overvoltage-Schutz aktiviert. | Check power supply connection; Ensure correct polarity; Verify input voltage is not above 24V. |
| Intermittent sound or skipping | Loose audio input connection; Overheating. | Secure audio input cable; Ensure adequate ventilation for the module. |
