Model Description:
SD-SDI Analog Audio Embedder

Model Details

The 7721AE-A4 Analog Audio Embedder performs A/D conversion on 4 balanced pairs of analog audio (as one audio group) and embeds them into a 270Mb/s serial SD input video signal as specified by SMPTE 272M. The companion 7720AD-A4 Audio De-embedder facilitates audio de-multiplexing at the destination.

The 7721AE-A4 occupies one card slot in the 3RU frame (7700FR-C), which will hold up to 15 1-slot modules or one slot in the 1RU frame (7701FR), which will hold up to three modules. The 7721AE-A4 also comes in a standalone unit (S7701FR).

VistaLINK® enables control and configuration capabilities via Simple Network Management Protocol (SNMP). This offers the flexibility to manage the module status monitoring and configuration from SNMP enabled control systems such as Evertz VistaLINK® PRO.



  • Automatic detection of video input format
  • Supports 270Mb/s SD per SMPTE 59M-C, and SDTi per SMPTE 305M
  • Programmable audio delays (up to 5 frames or 84 milliseconds)
  • Selectable ancillary packet cleaning mode removes all audio before embedding
  • Individual audio channel assignment for embedded audio group
  • Audio mixer per audio channel to provide voice-over
  • Upstream embedded Dolby E compatible (passed through)
  • Monitoring headphone jack for audio input and embedded audio output
  • Comprehensive signal and card status monitoring via four-character card-edge display and LEDs
  • VistaLINK® - capable for remote monitoring and control via SNMP (using VistaLINK® Pro) when installed in 7700FR-C frame with a 7700FC VistaLINK® Frame Controller
