Dolby Surround and Pro Logic II Encoder DP563

The Dolby® Surround and Pro Logic II Encoder DP563 lets you create surround programming for distribution via all analog and digital stereo media. The all-digital Dolby DP563 encodes discrete four- or five-channel surround mixes into Left total/Right total (Lt/Rt) stereo for delivery via two-channel television and radio broadcasts, PC and console games, CDs, and VHS tapes.

Lt/Rt encoded stereo content provides thrilling surround sound on millions of home theater systems equipped with Dolby Pro Logic® or Pro Logic II decoding, while remaining fully compatible with stereo and mono playback.

The DP563 provides two surround encoding algorithms. The original Dolby Surround algorithm encodes Lt/Rt stereo with full-range Left, Center, and Right channels, plus a limited-range Surround channel, as intended originally for four-channel Dolby Pro Logic playback.

The Dolby Pro Logic II algorithm encodes Lt/Rt stereo with five full-range channels—Left, Center, Right, Left Surround, and Right Surround—for the most natural and involving surround experience that can be delivered via stereo media.

One Mix Serves All Needs

With its six digital input channels, the DP563 can create Dolby Surround or Dolby Pro Logic II encoded stereo directly from any discrete 5.1 mix, so that producers of 5.1 content for DTV can easily create a separate mix for distribution via stereo services. With Dolby E 5.1 content, metadata authored during production can enable the DP563 to create an Lt/Rt stereo mix exactly as specified by the producers.

The Dolby Multichannel Audio Decoder DP564 is an ideal companion to the DP563, letting you monitor your surround encoded mix for compatibility with mono and stereo playback, as well as decoding it to verify multichannel Dolby Pro Logic and Dolby Pro Logic II playback. The DP564 also provides comprehensive functions for setting up and controlling the monitoring environment.
