    Why is the karaoke scoring result wrong on my JVC CA-DXU10 Speaker System?
    • P
      Patricia BakerSep 18, 2025
      If the scoring result seems wrong (or “– –” appears) on your JVC Speaker System, it may be because the time of playback and singing along are too short to obtain a correct scoring result. Extend the duration of playback. Also, check if there is no sound from the microphone or the input level (MIC LEVEL) is too low; adjust the input level. Finally, ensure that you sing louder.
