    What to do if my Musical Fidelity Electra E20 Amplifier has no sound?
    • C
      Crystal StarkAug 1, 2025
      If your Musical Fidelity Amplifier produces no sound, several factors could be at play. First, ensure the volume isn't set to the minimum; if it is, simply turn it up. Also, check if headphones are plugged in, as this mutes the main output; unplug them if necessary. Verify that the mute function isn't activated on the remote; if it is, press the mute button again. Confirm that the power amplifier is correctly connected by checking the cables. Ensure that your speakers are properly connected by inspecting the speaker cables. Lastly, check that the correct input source is selected on your amplifier.

      Joseph McmahonAug 25, 2025
      If you're experiencing hum when listening to a turntable with your Musical Fidelity Amplifier, it may be due to incorrect earthing of the pickup arm cable. You can either connect or disconnect the pick-up arm earth wire to the earth terminal on the back panel to resolve this.
