Supplier News

The DAX-4200, available from IRT Electronics 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. This embedded audio extractor 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.

Features of the embedded audio extractor include:

  • 270 Mb/s SD-SDI, 1.485 Gb/s HD-SDI or 2.97 Gb/s 3G-SDI input and output
  • The embedded audio extractor can extract up to 4 AES signals from 2 groups
  • Indicators for presence of input (SDI) & audio within group (GRP)
  • The embedded audio extractor includes four 75  unbalanced AES outputs
  • External AES reference input
  • Cascadable - SDI output for connection to additional units
  • The embedded audio extractor includes front panel Status and Configuration controls
  • Simple Network Management Protocol (SNMP) capable
The DAX-4200 embedded audio extractor supports AES synchronous and asynchronous audio at 48 kHz, 24-bit audio data packets.
