The DAI-4200 is a high performance audio embedder for either 270 Mb/s SD-SDI, 1.485 Gb/s HD-SDI or 2.97 Gb/s 3G-SDI video signals.

Each DAI-4200 is capable of inserting up to two audio groups into an existing SDI video stream. An audio group consists of two AES signals, thus four AES signals are capable of being inserted over two audio groups. AES 1&2 constitute one audio group, AES 3&4 constitute the second audio group.

Group position selection is made by the front panel local controls, or remotely via SNMP. Existing embedded data packets may be either all removed or selectively replaced.

The DAI-4200 supports AES synchronous or asynchronous (HD-SDI & 3G-SDI modes only) 48 kHz 24-bit audio data packets. An audio presence indicator is provided for each input.

DIP switch settings allow optional colour bars or colour black to SDI output on loss of SDI input.

Two DAI-4200’s can be cascaded for insertion of audio into all four groups if required.

Simple Network Management Protocol (SNMP) monitoring and control is possible when mounted in an IRT frame fitted with SNMP capability.

The DAI-4200 is fabricated in IRT's standard Eurocard format and may be housed in a variety of IRT Eurocard frames alongside other standard modules.
