Ericsson RX8000 Audio Output Format, MPEG Audio, B.2.3 Dolby Digital AC-3Audio, B.3.1 General, Analogue Audio

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.

B.3 Audio Output Format

B.3.1 General

The RX8000 Receiver provides an independent stereo pair output for each audio channel. Analogue audio is always output and the following digital audio formats can be chosen from the User Interface and remote control interfaces:

•AES3 format

B.3.2 Analogue Audio

The RX8000 Receiver supports level control of the audio outputs. Independent control of each output of each stereo pair is provided via the User Interface and remote interfaces.

Audio output connector type: 9 way female D-type

Output level: +20 dBm nominal clipping level. Selectable in range +12 to +24 dBm.

Output impedance: 50 Ω (nominal).
