This unit is clean with the exception of some scratches on the left side of the front panel (see photos).   It is working perfectly.   This is a very useful unit for anyone involved in transfer work for archival video libraries.   An advantage of the DPS290 is that all outputs are active all of the time, which makes this an excellent choice for transcoding.

This is a Two Channel device, with completely separate I/Os for all functions on both channels.   Please note that the RGB/Component I/Os are available through the 15 Pin HD connectors.   These breakout cables are not available with this unit at this time.   The pinouts for the 15 Pin HD connectors are in the manual.


From Leitch:

The DPS-290 Component Transcoding TBC/Synchronizer is perfect for all tape formats, including U-Matic, U-Matic-SP, VHS, S-VHS, and Hi-8.  Available in single and dual channel configurations, the DPS-290 provides composite (NTSC), Y/C (S-Video) and component (Betacam/MII) inputs and outputs. Because all outputs are active simultaneously, the DPS-290 also functions as a transcoder, making it particularly well suited for inter-format editing and duplication applications.

A three line adaptive comb filter decoder provides wide bandwidth composite video performance, making the DPS-290 equally useful for synchronizing camera and satellite feeds or for decoding composite video sources into component, Y/C signals or RGB signals. Designed for use in mission critical applications, a composite video bypass relay instantly routes input and output signals together in the event of power loss or system failure. Standard features include digital recursive chrominance/luminance noise reduction, 3-dimensional RF dropout compensation and red/blue color balance controls. Special effects include freeze frame, freeze field, variable strobe and film mode strobe. Front panel controls and a back-lit LCD status display provide easy access to all proc amp and configuration functions including CAV output levels, vertical blanking width, Y/C horizontal delay, Y/C vertical delay and DNR modes. A 10-event scene memory permits all front panel settings to instantly be stored or recalled.
