DDP24 - Quad Speed multichannel Dolby Digital (Plus), Dolby HE AAC 5.1 and Dolby Pulse 2.0 encoder

Description

The DDP24 is a quad speed ADD-ON Multi channel Dolby Digital (plus), Dolby HE-AAC 5.1 and Dolby Pulse encoder. The card is designed for the use with the Synapse high efficient quad speed multiplexing audio bus. The quad speed bus enables ADD-ON cards to be connected with a master card and have both input and output signals connected to this card for convenient routing and integration. The card can be configured as a 4in/4out or 6in/2out module.

The DDP24 receives the discrete audio in PCM from one of the 4  (or 6) physical AES/EBU inputs or any of the 32 stereo pairs that can enter the card via the Quad speed Audio bus. The stereo AES/EBU signals are available on its 4 (or 2) physical output connectors, via the Internal Synapse bus directly to the master card or to the looping quad speed bus outputs. The same counts for the bitstream outputs that can be routed to the physical outputs, the quad-speed bus return path outputs or the quad speed bus looping outputs.

An additional level activated Voice Over processor is included. This processor detects a user defined signal level and then ducks the predefined channels that are used to mix the VO with. The VO can be applied to 8 stereo channels (user selectable). The DDP24 has the ability to use stream muxing in a Dolby Digital Plus environment. This stream contains both the (multi channel) audio stream as the audio description stream in a convenient single Dolby Digital Plus stream (single PID) or in a dual stream (dual PID) 

 The DDP24 gets is processing clock from the Master card and will operate fully clock synchronous with this master card. You can use the DDP24 stand alone by locking on AES1 to 4 or Ref 1 or 2.
