The Dolby DP524 is ideal for decoding and monitoring in telecommunications applications requiring high audio quality at efficient data rates. Uses include studio interconnection via T1 and ISDN for remote recording and postproduction applications, Dolby Fax, and other satellite systems applications.

The DP524 supports Dolby AC-2, Dolby Digital (AC-3)*, and MPEG-1 Layer II at data rates from 40 to 448 kbps. Dolby Fax and ISDN applications require the use of Dolby AC-2 at 256 kbps and a 48 kHz sampling rate. Dolby Digital (AC-3)* supports mono, dualmono, and stereo formats, at 32, 44.1, or 48 kHz sampling rates; MPEG-1 Layer II supports single-channel, dual-mono (stereo), and joint-stereo formats at 32, 44.1, or 48 kHz sampling rates.

The DP524 accepts an encoded RS-449 serial data stream with timing information and automatically selects the appropriate decoding algorithm to recover the original audio and any auxiliary data. Synchronization is derived from either a user-provided external clock or the unit’s own internal clock. Both AES/EBU and S/PDIF digital outputs are provided, plus analog outputs with 20-bit D/A converters.

* Not suitable for new broadcast facilities requiring the latest version of the Dolby Digital (AC-3) codec.
