The model RLT-50 is RS-422 to LTC time code translator. It translates RS-422 "time code" obtained from any 9-pin VCR remote control connector into standard SMPTE Longitudinal Time Code (LTC). Use when LTC is not directly available from VCR (or other machine) for operating audio synchronizers, making LTC copies or use with other HORITA LTC products to make window dubs, log source tapes. Switch selectable –1 frame "search offset" when translating at search speeds or at still frame compensates for the +1 frame "on-time" updating done by many downstream LTC readers, edit controllers and other LTC products.
