Amplifiers support FAQ

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

  • How do I pair my Bluetooth amplifier to my mobile device?

    Set the amplifier input switch to Bluetooth, turn it on, and select the device (e.g., 'HiFi') from your mobile device's Bluetooth menu. Allow a few moments for the devices to connect.

  • Can I use bare wire for speaker connections on my stereo amplifier?

    Yes, many stereo amplifiers feature binding posts that accept bare wire, standard banana plugs, or spade terminals. Always ensure the amplifier is powered off before connecting speakers.

  • Why is the volume low when using the AUX input on my drum amplifier?

    If you are using an audio connection cable with a built-in resistor, the volume level may drop significantly. Use a standard straight audio cable without a built-in resistor for optimal input volume.

  • What should I do if my public broadcasting amplifier experiences interference?

    Try reorienting or relocating the receiving antenna, increasing the distance between the amplifier and receiver, or plugging the amplifier into a completely different electrical circuit.
