Miranda ADX-1881-3RU 2 AES digital audio de-embedder - ADX-1881-3RU



The ADX-1881 is a high-quality AES de-embedder designed to extract eight 24-bit 48 kHz digital audio signals, ancillary timecode (ATC), longitudinal/linear timecode (LTC) and ancillary data from a single SMPTE 292M HD-SDI or SMPTE-259M-C SD-SDI signal. The ADX-1881 will output audio silence with a loss of the input signal. The card provides automatic input format detection, as well as automatic equalization. An RS-422 serial data signal output is available to provide Dolby E metadata output, or simply to output a serial RS-422 signal. Two opto-isolated GPI data output signals can be reconstructed from ANC data inserted by the embedder. By combining AMX-1881 embedder and ADX-1881 de-embedder cards, a full duplex link may be established.

Key Features


  • HD/SD-SDI input with automatic equalization

  • Automatic detection of video input format

  • Two pass-through HD/SD-SDI video outputs

  • 8 AES outputs at 110 ohm balanced or 75 ohm unbalanced, depending on rear panel in use

  • Audio level adjustment, -96 to +12 dB

  • Selectable audio delay of up to 3 frames in 1/2 frame steps

  • 24-bit digital audio de-embedding

  • Built-in audio test tone signal

  • Audio silence output on loss of video input

  • Left/right channels swappable for each AES output

  • Selectable routing of audio groups to AES outputs

  • Co-phased audio outputs

  • Dolby E compatible

  • RS-422 serial data output signal reconstructed from ANC data inserted by the embedder. Output can also be Dolby E or Dolby Digital

  • Metadata embedded in VANC with proprietary DID

  • Linear timecode (LTC) output translated from ancillary timecode (ATC) data or digital vertical interval timecode (DVITC)

  • Two opto-isolated GPI data output signals reconstructed from ANC data inserted by the embedder

  • By combining AMX-1881 embedder and ADX-1881 de-embedder cards, a full duplex link may be established
