RM-HD1 Reference Monitor HD-SDI Expansion Card.
RM-HD1 Reference Monitor HD-SDI Expansion Card
This expansion board allows the monitoring of embedded non-encoded linear PCM audio channels within an SD/HD-SDI video signal.
The RM-HD1 card can be used with the RM-2S4, RM-2S10 and RM-4C8 monitors.
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 2 channels can be selected to be monitored on the speakers (for the RM-2S4 and RM-2S10, stereo pairs are selected; the RM-4C8 allows any 2 channels to be monitored). 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 to
provide a reclocked output to pass to external equipment such as another reference monitor.
