Dolby Atmos

1130

Dolby Atmos is a unique new technology for enjoying

the latest surround sound. In a movie theater,

overhead speakers are placed, with a multi-layer

approach to the sound design. On top of the

conventional channel-based soundtrack, object-oriented mixing

is used to layer dynamic sound elements, so regardless of the

theater's speaker setup, independent sound elements can move

around freely in a three-dimensional space. Compared to Dolby

Digital with discrete channels, Dolby Atmos offers seamless

surround sound movement with up to 64 separate speaker

output and a sense of height created by the overhead speakers.

The sound is completely in sync with the screen view, providing

total immersion with unprecedented sound localization and

movement.

This theater sound experience can be reproduced in your home

with Pioneer's Dolby Atmos AV receiver, which not only decodes

Dolby Atmos, but also reproduces Dolby Atmos in an ideal

sound stage fine-tuned by MCACC Pro.

What's more, with MCACC Pro room calibration technology, the

AV receiver not only adjusts the speaker distance, level, and

tones, but also the phase differences for precise sound delivery.

When using Dolby Atmos enabled speakers, MCACC Pro uses the

Bass Management System to bring out the best from Dolby

Atmos. You can fully appreciate the object effects of Dolby

Atmos with more clear and accurately positioned theater sound.

Dolby TrueHD

830

530

Dolby TrueHD delivers sound that is on par with

the original soundtrack, letting you experience

the world of true high-definition entertainment from Blu-ray

Discs. With lossless encoding in up to 18 Mbps bit rate, Dolby

TrueHD creates a synergy with high-definition video to offer you

a home theater experience like never before.

Dolby TrueHD Loudness Management

1130

830

Dolby TrueHD Loudness Management frees you from annoying

volume fluctuations that often occur when switching channels,

programs, or input sources, by maintaining a consistent loudness-

level. The function turns on/off during content playback, activating

or deactivating post processing within the decoder. When the

function is turned off, audio is delivered in a lossless mode.

DTS-HD Master Audio

1130

With DTS-HD Master Audio, you can

enjoy sound that is bit-for-bit identical

to the studio master, at 192 kHz/24-bit

for 5.1 channels and 96 kHz/24-bit for 7.1 channels. DTS-HD

Master Audio delivers audio at extremely high variable bit rates

of 24.5 Mbps, which far exceeds standard DVDs. DTS-HD Master

Audio offers movies and music in the pure, original state as

intended by the artists.
