RM-HD1 Reference Monitor HD-SDI Expansion Card &
RM-HDE1 Reference Monitor HD-SDI & Dolby E Expansion Card
These expansion boards for the Sonifex Reference Monitor allow the monitoring of
embedded audio channels within an SD/HD-SDI video signal. The embedded audio can be
either non-encoded linear PCM (RM-HD1), Dolby E Decoder or Dolby Digital Decoder
(RM-HDE1) depending on which card is used.
The expansion board can extract two AES/EBU groups (4 stereo pairs) from the video
signal and pass them to the main Reference Monitor unit for monitoring. The input is
autosensing for either SD or HD input formats and the extraction of embedded audio
complies with SMPTE-272 (SD) and SMPTE-299 (HD).
The SDI input is equalized, internally reclocked and re-transmitted via the SD/HD-SDI
output to provide a reclocked output to pass to external equipment such as another
reference monitor.
