What to do if my Marantz Amplifier PHA3 has no sound or distorted sound?

  Howard EwingJul 27, 2025
  If your Marantz Amplifier PHA3 isn't producing sound or the sound is distorted, first ensure all cable and device connections are securely and correctly connected. Check for any damage to the cables. Also, verify that the settings on your loudspeaker or mixer are properly configured. If distortion persists, try reducing the Level knobs and/or the level of the audio signal sent into the line inputs and Stereo/Loop In.

  If your Marantz Amplifier power isn't turning on, check the power adapter to ensure it's properly connected to both the power input and the power outlet. If you're using batteries, make sure they are correctly installed in the battery compartment, inserting the positive (+) end first. Also, confirm that the power switch is set to the correct position: 'Ext' for power adapter use, or 'Batt' for battery use.
