ISIS 4461A

Model Details

The 4461A SDI analog audio embedder embeds two balanced stereo audio pairs into the ancillary data space of a 270Mb/s SDI stream. The analog input is sampled at 24 bits and can be embedded as 20 or 24 bit audio. Embedding conforms to SMPTE 272M and allows audio to be inserted into any of the four groups. Existing audio groups can be added to or completely removed. Digital silence is inserted when an audio feed is absent. 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.
