AVP Transmitter Audio Downmixing


AVP Transmitters are the only models that process audio in a Just Add Power system. AVP Transmitters will accept stereo audio or Dolby® Digital 5.1, but no higher-level audio formats. When an AVP Transmitter receives a Dolby Digital 5.1 audio signal, the audio signal is encoded to 2-channel audio using the Dolby Pro Logic II® codec. These model numbers are AVP Transmitters:

  • 718AVP
  • 718WP4
  • 749AVP

The audio conversion occurs on the Transmitter entirely. Once the signal has been converted, any Receiver model can process the converted audio. A stereo-capable display will get stereo audio from the Receiver. A Dolby Surround-capable AVR will use Dolby Pro Logic II to decode the signal and provide 5.1 discrete channels: Left, Right, Center, Left Surround, Right Surround, and LFE.

Planning Considerations

An AVP Transmitter is ideal in these circumstances:

  • A source outputting Dolby Digital 5.1 - cable, satellite, streaming device - that needs to be distributed to stereo and surround zones simultaneously
  • A source outputting stereo or Dolby Digital 5.1 that needs to be fed into an analog audio distribution system

For information on the different ways that Just Add Power Transmitters handle audio for planning purposes, please see the Transmitter Audio Planning article.
