Most film soundtracks today are mixed using mag film with SR, even those destined for digital release, and it remains the industry-standard archival format. And that is a key factor in the continuing sales of hundreds of new Dolby SR channels each month, and the total number in use around the world having now surpassed 100,000. Model DP503 encoder provides three popular algorithms. Model DP524 decoder features automatic algorithm detection. Supporting data rates between 40 and 448 kbps, the DP503 and DP524 are ideal for distribution systems requiring both high audio quality and low, spectrum-efficient data rates.
Clock synchronization is derived from either an internal data clock or the user's external clock.
The front panel features an alphanumeric display that facilitates storing codec parameters and selecting algorithms. Codec parameters can also be stored along with ISDN phone numbers for remote locations, enabling virtually automatic ISDN interconnection. A converters for the latter. Both encoder and decoder provide front panel system status indicators, rear panel logic level tallies, and test tone generators for system set up and troubleshooting. Dolby Laboratories Inc.
