Critical monitoring of your signal is essential to ensure that the highest quality audio reaches your listeners at home. As our reference decoder, the Dolby DP564 is the ideal monitoring tool for all quality-control applications. Using the DP564, you can decode and monitor programs with Dolby Digital, Dolby Digital Surround EX, Dolby Pro Logic and Pro Logic II, as well as regular two-channel PCM soundtracks.

Control Flexibility

The DP564 provides easy selection and monitoring of Dolby Digital's unique downmixing capabilities, listening modes, and compression modes. This gives content producers and providers an accurate way to verify how material originally produced and transmitted in 5.1 will sound when played back through Dolby Pro Logic or Pro Logic II, two-channel stereo, or mono home systems. Built-in Dolby Headphone processing, with a dedicated volume control, allows monitoring surround sound over standard headphones. The 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.

Inputs and Outputs

There are three digital inputs (one a Toslink optical) and an Ethernet port for RTP streaming Dolby Digital audio. A linear timecode (LTC) output allows DVD facilities to check A/V sync between audio encoded in Dolby Digital and uncompressed video. Front- and rear-panel serial interfaces, along with the Ethernet port, facilitate software remote control (supplied) and software updates via a PC. A rear-panel GPI/O port also offers remote control from the Dolby Cat. No. 549 GPI/O controller or other external source.

The ideal companion encoder units are the Dolby DP569 for creating Dolby Digital material, and the Dolby DP563 for encoding into Dolby Pro Logic II and Dolby Pro Logic.
