DE-EMBEDDING

audio for video

Features The 2DB22 contains two fully independent digital audio de-embedders. This card allows for 36 deembedders in 4 Rack Units, and has its counterpart in the mirror image 2EB22.

2 x 2 AES/EBU outputs 110 Ohm balanced digital audio outputs on sub-D 2 x 2 reclocked SDI output Single channel mode for de-embedding (2 group de-embedder) 4 x AES/EBU out of a single SDI Audio level control for each individual channel -60 to +12dB Phase Control per output channel 0 or 180 deg Free selection of all embedded channels (any out of 16) Locks to SDI input Full control and status monitoring through the front panel of the SFR04/SFR08/SFR18 frame and the Ethernet port (ACP) Optional 2 fiber inputs (replacing 2 SDI inputs) or 2 fiber outputs (replacing 2 SDI outputs) on I/O panel Optional 2 CVBS outputs (replacing 2 SDI outputs) on I/O panel

Applications

Generic multi channel digital audio de-embedding 2 group (4 AES/EBU) de-embedding High density applications as in OB-Trucks
