Description
The 4462DB SDI balanced AES/EBU audio de-embedder extracts two digital stereo audio streams from any group in the ancillary data space of a 270Mb/s SDI stream. De-embedding conforms to SMPTE 272M and allows audio to be extracted from any of the four groups. The audio outputs are muted when no embedded audio is present. There is automatic input cable equalization and a re-clocked SDI output.
The unit is housed in an extremely compact and rugged aluminum case and is suitable for both field and studio applications.
