Please use the following steps to confirm if the unit is configured and passing audio as intended:

  • Check for update
  • Ensure cables are securely connected between the MDX and your source devices
  • Ensure that Speaker wires are securely fastened to the MDX and the Speakers
  • Be sure that the MDX Web UI is properly configured. 

The simple way to test would be to set the On Mode Switch to Auto Mode, connect a local source to input 1, adjust the volume to a reasonable level on the source device, and play source content, this should automatically turn on Zone 1 and begin to play through the connected speakers.
