The XDED (NEXUS Dolby E® Decoder) board is a slide-in board for decoding Dolby E® and Dolby D (AC-3) signals on NEXUS systems. The board comprises a base plate with two module slots that can be populated with Dolby OEM modules. Thus, the board allows for decoding up to two encoded audio streams to linear PCM. In addition, it provides two audio channels for un-encoded audio that can be used either for carrying an accompanying stereo signal or as commentary channel.
Decodes Dolby E/D signals from AES/EBU D-Sub (15-pin, female) or TOSLINK optical inputs
Decodes up to 8 separate signals from a Dolby E/D data stream plus a stereo output for downmix signals (configurable downmix)
Decodes metadata for output as XTI signals or via the XDEM optical interface board
2 audio channels for forwarding unencoded audio from the NEXUS system or from AES/EBU inputs with optional delay and gain
Video-sync input (BNC) for bi-level and tri-level sync signal
Direct connectivity to SDI boards for cascading 2 XDED boards (option)
Sample-rate converters on all audio channels
External inputs and XDEM metadata outputs with galvanic isolation
Officially certified by Dolby for Dolby E signal transmission
