  • Flexible HD/SD reference using the internal URS frame reference or a dedicated reference input
  • Support of one SFP+ cage for SDI fiber I/O on selected rears:
    • 12G SFP and 3G SFP R, T, RT and TT models available
  • LTC I/O embedding/de-embedding into/from ATC
  • 8 AES3-id 75Ω, or AES3 110Ω, I/Os
  • MADI I/O using dedicated connector
  • 16 audio channels embedder/de-embedder
  • 16 channels internal audio processing
  • Full audio shuffling and mixing on a channel basis.
  • Two slots rear (BNC connectors) in Densité 3 or 3+ frames
  • One slot rear (HD-BNC connectors) available in Densité 3+ frames
