RM-HDE1 Reference Monitor HD-SDI & Dolby® E Expansion Card.
RM-HDE1 Reference Monitor HD-SDI & Dolby® E Expansion Card
This expansion board allows the monitoring of embedded audio channels within an SD/HD-SDI video signal. The embedded audio can be either
non-encoded linear PCM, Dolby® E or Dolby® Digital (RM-HDE1) depending on which card is used.
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 allowing you to view L, R, C, LFE, Ls, Rs for Dolby Digital and an additional Lt, Rt for Dolby E.
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 autosensing for either SD or HD input formats and the extraction of embedded audio complies with SMPTE-272 (SD) and SMPTE-299 (HD).
The HD-SDI input is equalized, internally reclocked and re-transmitted to provide a reclocked output to pass to external equipment such as another reference monitor.
