    What to do if the CLIP indicator lights on my Inter-m M-1500 Amplifier?
    • D
      Desiree ColeJul 31, 2025
      If the CLIP indicator lights on your Inter-m Amplifier, it means the amplifier load is excessive. To resolve this, use a speaker system with an impedance of at least 4 Ohms (stereo) or 8 Ohms (bridge).

    Why does the PROTECTION indicator light turn on on my Inter-m M-1500?
    • M
      Monica FisherAug 11, 2025
      If the PROTECTION indicator lights on your Inter-m Amplifier, it could be due to the heat sink temperature exceeding 100°C. Ensure proper ventilation around the amplifier to improve airflow.

      Cheryl TaylorAug 19, 2025
      If the –40dB indicator is the only light that is on on your Inter-m Amplifier, it indicates a short at a speaker terminal, amplifier terminal, or wire. You should locate and correct the cause of the short.
