Sonifex RM-HDE1 - HD-SDI & Dobly E Decoder Expansion Card for RM-4C8

This Sonifex RM-HDE1 expansion board allows the monitoring of embedded audio channels within an 3G/HD/SD-SDI video signal. The embedded audio can be either non-encoded linear PCM, Dolby® E or Dolby® Digital. Please note that the RM-HDE1 card is for use with the RM-4C8 unit only.

The expansion board can extract any selected AES/EBU audio group (4 channels) from the video signal and pass them to the main Reference Monitor unit for monitoring. Any group can be selected. All channels in the selected group can be monitored visually and any 2 channels can be selected to be monitored on the speakers. If a Dolby E or Dolby Digital input is detected on the selected channel, the Channels (CHANS) button flashes to indicate that decoding is possible. Pressing the CHANS button displays the Dolby Digital 5.1 or Dolby E 8 channel signal, using the 4 bar-graph meters.  Each meter is split into 2 sections, top and bottom, allowing you to monitor all 8 channels coming from the Decoder.

Full Dolby Metadata is available using the SCi remote control software. For a more detailed description of Dolby Decoding operation please refer to the Reference Monitor handbook.

The input is auto-sensing for either SD, HD or 3G input formats and the extraction of embedded audio complies with SMPTE-272 (SD) and SMPTE-299 (HD/3G). The SDI input is equalized, internally re-clocked and re-transmitted to provide a re-clocked output to pass to external equipment such as another reference monitor.
