Based on technology first seen in the market leading D-10, the D-15 features 8 Mbit of DRAM on-card to provide instant start, ‘RAM scrub’ and ‘RAM repeat’ with 1 ms accuracy for precision cueing with advanced jog/shuttle techniques. In addition, this facility has been utilised to provide the simulated ‘vari-speed’ required to enable a linear DAT transport to perform the chase synchronisation offered when the optional 8335 timecode expansion card is fitted.
