The DAX-3206 is a high performance embedded
audio extractor for 270 Mbit SDI video signals. It is
primarily designed to operate with IRT's DAI-3206
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-3206 is
capable of extracting one audio group (2 AES / 4
analogue) from those available. Selection is made via
a front panel local control switch.
The DAX-3206 supports AES/EBU synchronous and
asynchronous audio at 48kHz, 20-bit audio data
packets.
Both analogue and digital audio outputs are provided
so that the one module may be used for all
applications in monitoring and processing.
The use of digital audio filtering and 20-bit digital to
analogue converters produce studio quality analogue
audio and the AES/EBU digital interface allows
digital interconnection in either balanced or
unbalanced formats. |
An audio presence indicator is provided for each
group output. If no audio is detected the
corresponding output is muted.
The DAX-3206 complements the DVC-4112 SDI to
analogue video converter for full conversion of SDI
signals to analogue video and audio.
The DAX-3206 comes configured standard with
110 Ω balanced AES/EBU outputs. 75 Ω unbalanced
outputs are available by insertion of links on the rear
assembly.
The DAX-3206 is fabricated in IRT's standard
Eurocard format and may be housed in a variety of
IRT Eurocard frames alongside other standard
modules. |
