The 520AD8-HD Audio De-embedder extracts embedded audio from all 4 groups as defined by SMPTE ST 299-1 from a 1.5Gb/s serial HDTV or as defined by SMPTE ST 272 from a 270Mb/s serial SDTV video signal. Up to 16 selected channels may be de-embedded and directed to 8 AES outputs.

This device also handles the Dolby-E Metadata. Metadata is optionally de-embedded from VANC and can be provided as an output for downstream devices (i.e. Dolby-E or Dolby AC3 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 520AD8-HD is housed in the 3RU 500FR Exponent frame that will hold up to 16 modules.
