Nobsound support FAQ

Pirsên gelemperî di derbarê rêbernameyan, qeydkirin û piştgiriya vê marqeyê de.

  • Why is there no sound coming from my Nobsound amplifier?

    First, check that the power supply is securely connected and the amplifier is turned on. Ensure the correct input channel is selected and the volume is not set to the minimum. Verify that the audio source (e.g., phone, PC) is playing and not muted.

  • Why is the sound distorted on my Nobsound device?

    Distortion often occurs if the input signal level is too high. Try lowering the volume on your source device (like a computer or phone) and increasing the volume on the amplifier. Also, ensure your speakers match the impedance and power requirements of the amp.

  • Why do I hear a buzzing or humming noise?

    Background noise can be caused by unshielded signal cables or interference from the power supply. Try using high-quality shielded audio cables, keeping cables away from power cords, or testing with a different power outlet.

  • Can I replace the vacuum tubes on my Nobsound amp?

    Yes, many Nobsound models allow for tube rolling (replacing tubes). However, you must turn off the device and let the tubes cool down completely before touching them to avoid burns or electrical shock. Only use compatible tube models.
