The Dolby DP564 is a multichannel Dolby Digital audio reference decoder for DTV broadcast, postproduction, DVD authoring, and game development. It supports Dolby Digital, Dolby Digital Surround EX, Dolby Pro Logic, Dolby Pro Logic II, and regular two-channel PCM soundtracks.
Dolby no longer manufactures this product but will continue to support it as per warranty. Check our list of partner products for more options.
Critical monitoring of your signal is essential to ensure that the highest-quality audio reaches your listeners. As our reference Dolby® Digital decoder, the Dolby Multichannel Audio Decoder DP564 is the ideal monitoring tool for all quality-control applications.
The Dolby DP564 provides easy selection and monitoring of Dolby Digital's unique downmixing capabilities, listening modes, and compression modes. This gives you an accurate way to verify how material originally produced and transmitted in 5.1 will sound when played back through Dolby Pro Logic® or Dolby Pro Logic II, two-channel stereo, or mono home systems.
Built-in Dolby Headphone processing, with a dedicated volume control, allows you to monitor surround sound over standard headphones. The Dolby DP564 provides a comprehensive set of functions such as test noise, speaker trims and delays, bass redirection, mutes, and solos for the configuration and control of multichannel monitoring environments.
The Dolby GPI/O Controller CAT549 provides basic remote-control functions for the Dolby Multichannel Audio Decoder DP564 and Dolby Multichannel Audio Tool DP570.
It extends the processor's basic front-panel functions and controls from the rack to the user and provides basic remote-control functions including volume, mute, and dim, as well as 12 user-assignable tasks. Its removable cover permits console monitoring.
