The Dolby DP570 provides unprecedented control and reference monitoring for the creation and delivery of Dolby Digital and Dolby E surround sound and metadata for DTV and DVDs.
The DP570 Multichannel Audio Tool greatly simplifies the preparation of content intended for Dolby® E and Dolby Digital encoding applications. Its ability to completely configure and control the monitoring environment and set metadata parameters makes it the key product for postproduction, DVD, and DTV facilities that master, author, or broadcast program material with Dolby surround sound audio. Users can monitor exactly what the consumer ultimately hears on these programs.
The DP570 makes it possible to take full advantage of audio metadata, the unique “data about the data” that Dolby Digital bitstreams deliver to consumer decoders. Metadata ensures that home listeners will hear programs as their producers originally intended. The DP570 enables the user to create new metadata, and to modify any metadata generated throughout the production and distribution process. In addition, it includes the ability to determine and to properly set the dialogue normalization (dialnorm) value using the ITU-R BS.1770-1 algorithm.
The effect audio metadata has upon the reproduced programming can be monitored in real time, without the need for a Dolby Digital encoder and decoder. The DP570 outputs metadata as a separate data stream, to be combined later with the multichannel audio by a Dolby E or Dolby Digital encoder.
The DP570 accepts up to eight audio channels configured as four digital pairs, and it has two independent sets of outputs. One set provides the multichannel program signal in the SMPTE-recommended channel assignment, via a user-controllable builtin router. The second, the “emulator” set, facilitates monitoring in different listening modes without affecting the main audio path.
The DP570 is particularly useful in conjunction with audio consoles lacking adequate multichannel monitoring facilities. With the addition of the high-performance 24-bit Cat. No. 548 Analog Option Card, 5.1-channel, two-channel, and mono outputs are available to feed three speaker systems independently; the card also gives users control over levels, channel mutes, and channel solos. An additional input and built-in Dolby Pro Logic® II and Pro Logic decoders also allow proper monitoring of Lt/Rt sources and downmixes from all other inputs.
The DP570 contains extensive GPI/O control and includes a software remote application for use with a Windows®-based PC. Optionally, the Cat. No. 549 GPI/O Controller provides key remote control functions.
