GeckoFlex 8920DMX SD & Digital Audio De-Embedder

This companion to the 8920MUX simplifies the management of multi-channel audio by extracting up to two 48 kHz AES audio streams (up to four discrete channels) from one of the eight available AES groups in the ancillary data space of embedded 525 or 625 serial digital component video. The 8920DMX recognizes and preserves the ID and channel status of the 20- or 24-bit AES group and can delete groups assigned for extraction or pass them through to another demultiplexer. The two AES/EBU outputs can be either 75Ω unbalanced or 110Ω balanced to accommodate a variety of digital audio processing equipment.

  • Extracts up to two AES/EBU streams
  • Supports 48 kHz audio
  • EDH detection
  • 75Ω unbalanced or 110Ω balanced digital audio outputs
  • Supports networked control and monitoring
