The REF-1801 from Grass Valley is a reference module that distributes a universal reference signal (URS) to all the cards within a Densite frame. It can also optionally generate two selectable reference signals for external use. The unique URS concept provides significant advantages as it generates a digital reference signal, and also simplifies interformat processing by using a unique reference signal for all video and audio frame rates. The REF-1801 has the ability to extract timecode from the input as per SMPTE-318M, whichallows for perfect audio/video phasing. Other features include the ability to slave Densit‚ frames, as well as advancing or delaying independently the two reference output signals.
Please Note: Rear Modules are sold seperately. Also note that the REF-1801 card has to be installed in slot 10 of the Densit‚ 2/Densit‚ 3 frame.
