9. Fejlfinding

If you encounter issues with your Hilitand NE5532 Preamp Board, refer to the following troubleshooting steps:

Problem	Mulig årsag	Løsning
Ingen lydudgang	Ingen strøm eller forkert strømtilslutning. Input/output cables not connected properly. Lydstyrkeknappen er indstillet til minimum. Audio source not playing or faulty.	Verify AC Dual 12-18V power supply is connected and functional. Check all audio input and output cable connections. Skru op for lydstyrkeknappen. Test the audio source with another device.
Forvrænget eller uklar lyd	Indgangssignalet er for stærkt. Faulty audio cables. Ustabil strømforsyning. Damaged components on the board.	Reduce the output volume of your audio source. Udskift lydkabler. Ensure power supply is stable and within specified voltage. Hvis forvrængning fortsætter, kontakt support.
Brummende eller summende lyd	Problem med jordsløjfen. Dårligt afskærmede kabler. Interferens fra andre elektroniske enheder. Ustabil strømforsyning.	Ensure proper grounding for all audio equipment. Brug afskærmede lydkabler af høj kvalitet. Move the preamp board away from other electronic devices that may cause interference. Check power supply for stability.
Tone controls have no effect	Faulty tone control potentiometers. Problem med det interne kredsløb.	Gently rotate the knobs to see if there's any response. If no response, contact support.
