DMX6800+A4B2D, +A4C2D

Analog/AES Audio De-Embedders

The DMX6800+A4B2D/+A4C2D series analog audio and AES digital audio de-embedder modules for the 6800+™ core processing platform accepts an SD-SDI input with embedded audio and de-embeds up to four analog audio outputs and two balanced or unbalanced AES outputs. Part of the 6800+ platform, the modules also provide one SDI reclocked output.

Four variations of DMX6800+ analog/AES audio de-embedder modules are available:

  • DMX6800+A4B2D — provides four analog audio output channels and two balanced AES outputs from the SDI video input; includes DARS input and re-clocked SDI output 
  • DMX6800+A4B2ZD — provides same as above, except the analog audio outputs are 600 ohms high impedance
  • DMX6800+A4C2D — provides four analog audio output channels and two unbalanced AES outputs from the SDI video input; includes DARS input and reclocked SDI output 
  • DMX6800+A4C2ZD — same as above, except the analog audio outputs are 600 ohms high impedance

The DMX6800+ modules can be controlled manually via card-edge controls, or controlled and monitored via the CCS Navigator™ software application, HTTP web browser, NUCLEUS™ hardware control panels or third-party SNMP-based control applications.

Features

  • SDI video input with auto-detect

  • Up to two AES output channels (balanced or unbalanced)
  • Ability to demux any channel within four groups
  • Internal audio processing amplifier (gain, invert, and channel swapping)
  • Selectable 16-, 20-, or 24-bit audio processing
  • C-bit, U-bit, and V-bit transparency
  • Adjustable audio delay, up to 1.3 seconds
  • User-selectable on/off mute function for audio errors
  • Input video status
  • Supports card-edge and remote control of module (via CCS Navigator, web browser and third-party SNMP-based control applications)
