Features The DBD18 is a quad speed ADD-ON Dolby E decoder. 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 DBD18 receives the Dolby E from one of the 4 physical AES/EBU inputs or any of the 16 stereo pairs that can enter the card via the Quad speed Audio bus. The four decoded stereo AES/EBU signals are available on its local I/O connectors or via the Internal Synapse bus directly to the master card.

The DBD18 gets is processing clock from the Master card and will operate fully clock synchronous with this master card. You can use the DBD18 stand alone by locking on AES1 to 4 or ref 1 and 2.

For stand alone application we advice the DBD08
