The Dolby DP562 is a reference decoder
enabling production,mastering,and
broadcast facilities to monitor audio,video,and
multimedia programs with multichannel sound.
With features tailored to the needs of the profes sional user,the DP562 is an essential production
tool for both Dolby Surround formats and those
with Dolby Digital audio,such as DVD and
DTV.
The DP562 decodes Dolby Digital pro gram material with up to 5.1 channels.It also
provides four-channel Dolby Surround Pro
Logic decoding for matrix-encoded surround
material.The Pro Logic decoder has been
implemented digitally,making it possible to
monitor Dolby Surround encoded PCM
soundtracks in a studio setting without convert ing them to analog for surround decoding.
The 1-U high DP562 allows manual selec tion from four decoding modes: Dolby Digital,
Dolby Pro Logic,Dolby Digital + Pro Logic,
and PCM Pass-through.It can also be config ured to switch automatically to the Dolby Digital
mode when a Dolby Digital bitstream is detect ed; bitstream parameters are displayed on a two line,16-character LCD.Front-panel controls
allow selection of the various compression
modes for Dolby Digital’s dynamic range con trol and dialogue level normalization features.
A rear-panel interface provides remote control
permitting integration of the DP562 into auto mated facilities.It can also be remotely con trolled by a PC with application software.
The DP562 also makes it possible to
monitor Dolby Digital’s unique “downmix ing” capabilities. For example, in the Dolby
Digital + Pro Logic mode, a 5.1-channel
Dolby Digital input signal is automatically
mixed down to a two-channel (Lt/Rt) Dolby
Surround encoded signal, then processed
through the Pro Logic decoder. This permits
producers to verify what a home listener
would hear from material transmitted with 5.1
channels, but received by a two-channel Dolby
Digital decoder connected to a playback sys tem with Pro Logic decoding.
Other modes make it possible to monitor
what multichannel program material will
sound like when played on multichannel sys tems, mono or two-channel stereo systems,
surround systems without a center channel,
and systems with a center speaker but no
surrounds.
To set up the correct monitoring environ ment, the DP562 offers full bandwidth and
band-limited pink noise, individual channel
level trims, and center and surround channel
delays. The DP562 also has comprehensive
bass redirection capabilites
THE DP563 its an Encoder for both surround and Pro logic
All-digital encoding
The all-digital Dolby® Surround and Pro Logic® II Encoder 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, and CDs.
Thrilling surround sound
Lt/Rt encoded stereo content lets you provide 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.
Two encoding algorithms
The Dolby 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. If you're a producer of 5.1 content for DTV, you 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.
