520AD4-HD
HD/SD-SDI Audio De-embedder with 4 Unbalanced AES Outputs
The 520AD4-HD Audio De-embedder extracts embedded audio from 2 specified groups as defined by SMPTE 299M from a 1.5Gb/s serial HDTV or as defined by SMPTE 272M from a 270Mb/s serial SD video signal.
Up to 8 selected channels may be delayed up to 3 seconds and re-embedded onto the output video and/or directed to 4 AES outputs. An extra AES input is provided as a backup channel, in case of loss of primary, or as the source of voice-over. The video output may be optionally delayed up to 5 frames to achieve lip sync with the audio.
This device also handles the Dolby® E Metadata in VANC. The module has multiple sources for this metadata including VANC, and externally supplied metadata. The decoded or de-embedded Dolby® E metadata can be provided as an output for downstream devices (ie. Dolby® E encoders etc.).
VistaLINK® enables control and configuration capabilities via Simple Network Management Protocol (SNMP). This offers the flexibility to manage the module status monitoring and configuration from SNMP enabled control systems such as Evertz VistaLINK® PRO locally or remotely.
The 520AD4-HD is housed in the 3RU 500FR 
frame that will hold up to 16 modules.
