The DAX-4200 is a high performance embedded
audio extractor for 270Mb/s SD-SDI, 1.485Gb/s HD-SDI or 2.97Gb/s 3G-SDI video signals. It is
primarily designed to operate with IRT's DAI-4200
digital audio inserter but will work on any embedded
SDI source.
A typical SDI signal may contain up to eight audio
pairs arranged in four groups. Each DAX-4200 is
capable of extracting two audio groups (AES 1&2 and AES 3&4) from those available. Selection is made via
a front panel local control switch, or via SNMP.
The DAX-4200 supports AES synchronous and
asynchronous* audio at 48kHz, 24-bit audio data
packets.
*Asynchronous mode possible for HD-SDI & 3G-SDI only. |
A group presence indicator is provided for each group containing audio data. If no audio is detected in the selected group the corresponding outputs are muted.
Simple Network Management Protocol (SNMP) monitoring and control is possible when mounted in an IRT frame fitted with SNMP capability.
The DAX-4200 is fabricated in IRT's standard Eurocard format and may be housed in a variety of IRT Eurocard frames alongside other standard modules. |
