General:
The DAX-4200 is a high performance embedded
audio extractor for either 270 Mb/s SD-SDI,
1.485 Gb/s HD-SDI or 2.97 Gb/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.
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.
The DAX-4200 supports AES synchronous and
asynchronous* audio at 48 kHz, 24-bit audio data
packets.
* Asynchronous mode possible for HD-SDI & 3G-SDI only.
