The D10A provides exceptional quality component-only analog to 10-bit SD-SDI. The superior quality of this
10-bit A/D converter has made it a favorite of the professional video engineer. The D10A is pre-set at the factory
to accept either YPbPr (SMPTE, EBU/N10), Betacam, or RGB in 525 or 625 line formats, converting the analog
component signal to 10-bit SDI. The D10A has three BNC’s for one component input, one external sync input, and
three SDI outputs. Input formats can be reset by internal jumpers and level/gain controls.
