AIYIMA support FAQ

Common questions about manuals, registration, and support for this brand.

  • Why is there no sound output from my AIYIMA amplifier?

    Check if the power supply is connected and the unit is turned on. Ensure the correct input mode is selected and that all audio cables are securely connected. Also, verify that the audio source is not muted or set to minimum volume.

  • Why is the sound distorted?

    Distortion often occurs if the input signal level is too high. If both the audio source volume and the amplifier volume are maxed out, try lowering the volume on the source device.

  • Why do I hear a buzzing or humming noise?

    This can be caused by a low-quality power supply or unshielded signal cables. Try using the original power adapter or replacing the audio cables with shielded ones. Disconnecting inputs can help isolate if the noise is internal or from the source.

  • How do I switch to Bluetooth mode?

    Toggle the input switch to the Bluetooth position (often indicated by a flashing light). On your mobile device, search for 'AIYIMA' or the specific model name in Bluetooth settings and pair.

  • Can I replace the vacuum tubes on my AIYIMA preamp?

    Yes, many AIYIMA tube amplifiers allow tube rolling. Common replacements include 6K4, 6J4, GE5654, or 6*1N tubes. Always ensure compatibility with your specific model before swapping.

  • What is the warranty period for AIYIMA products?

    AIYIMA typically offers a one-year or two-year warranty depending on the specific product and region. Refer to the warranty card included in the manual for exact terms regarding free repair services.
