Introduction
The DP564 Multichannel Audio Decoder gives studio professionals unparalleled
ability to monitor different audio programs in a variety of listening modes.
Critical monitoring is essential to ensure that the highest quality audio reaches your
listeners at home. The DP564 Multichannel Audio Decoder, the next generation
reference decoder from Dolby Laboratories, is the perfect tool for monitoring and
quality control applications in DTV broadcast, postproduction, and DVD authoring.
The DP564 enables decoding and monitoring of programs with Dolby ® Digital,
Dolby Surround Pro Logic ® , or regular PCM soundtracks, as well as Dolby Digital
Surround EX ™ and Pro Logic II decoding, making the DP564 the ideal digital
reference decoder for both Dolby Digital and Dolby Surround audio.
With the DP564, you can easily monitor all of Dolby Digital’s unique downmixing
capabilities. This means content producers and providers can verify how material
delivered in a 5.1-channel format will sound on systems that offer only Dolby
Surround, two-channel stereo, or mono playback.
By switching between listening modes using the front-panel controls, it is possible to
monitor how any multichannel program will sound when played on fully configured
multichannel surround systems, as well as surround systems with no Center channel
(
Phantom
) or even systems with no Surrounds (
3 Stereo
). Compression modes can
also be selected from the front panel to easily monitor Dolby Digital’s dynamic range
control and dialogue normalization features. These features are tailored to
professional users to allow you to hear how your audio will sound on any set-top box,
DVD player, or home theater receiver.
To set up and control the monitoring environment, the DP564 offers comprehensive
monitoring functions—including a master volume knob on the front panel, channel
mutes, reference monitoring level, individual channel level trims, center and surround
channel delays, bass management, and both full and band-limited pink noise for quick
and accurate room calibration. The headphone output has its own volume control, as
well as Dolby Headphone processing, which provides surround sound monitoring
over standard headphones. This allows more accurate QC monitoring and reduced
listener fatigue for headphone listeners.
