Annex B
B.2.2 MPEG Audio
The RX8000 Receiver supports decoding of MPEG audio as follows:
• Compression layers: MPEG-1 layers I and II
• Sampling rate: 48 kHz
• Maximum compressed data rate: 384 kbps (layer II)
B.2.3 Dolby Digital AC-3 Audio
The RX8000 Receiver is able to decode and output the primary stereo pair of a
Dolby Digital AC-3 encoded audio stream. When there is data encoded on the audio
surround channels, the Decoder applies downmixing, so that either a surround
encoded stereo pair (LtRt downmix) or a conventional stereo pair (LoRo downmix) is
available at the output.
The RX8000 Receiver is not able to decode and output all 5.1 channels individually
as separate channels:
• Sampling rate: 48 kHz
• Maximum compressed data rate: 640 kbps
Note: Support for Dolby Digital decoding requires approval and licensing from
Dolby.

control of each output of each stereo pair is provided via the User Interface and
remote interfaces.
