Abstract: A synchronization system for multiple CD players (12), (14), (16) and (18) includes a controller (20) that generates four separate sampling frequencies for input to the word clock inputs of the CD players. A master word clock provides a master clock signal that is input to CD player (12) and then multiplied by multiplier (40). The output of multiplier (40) is divided down by variable dividers (48), (50) and (52) to provide the sampling frequencies for the remaining CD players (14), (16), and (18). Each of the disks (54) has a header (80) disposed on the beginning of each of the program tracks. This header has a unique synchronization signal associated therewith that outputs data corresponding to the position of the output digital data. During output of the data associated with the header, a difference between positions of the different CD players is determined.
