Overview

AVP Transmitters are the only models that process and convert audio in a Just Add Power system. AVP Transmitters will accept stereo audio or Dolby® Digital 5.1, but no higher-level audio formats. These model numbers are AVP Transmitters:

• 718AVP
• 718WP4
• 749AVP
• 718KVM + DSPKIT
• 749KVM + DSPKIT

Audio Processing

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.

• A stereo-capable display will get stereo audio from the Receiver.
• A Dolby Surround-capable AVR will get stereo audio. Set the AVR to Dolby Surround to tell it to 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
