    Why does the playback break up on my Marantz Amplifier?
    • P
      Patricia SmithSep 16, 2025
      Playback issues on your Marantz Amplifier can occur due to insufficient network bandwidth or a high file bit rate. Network communication may become congested. To resolve this, stop communication from other devices or consider redesigning your network environment.

    Why Marantz AV8003 Amplifier cannot play files even if the format is supported?
    • J
      Jennifer RodriguezSep 23, 2025
      Your Marantz Amplifier might not play files, even if the file format is supported, because the server does not support this file format. Only files whose formats are supported by both the unit and the server can be played.
