Dolby Atmos

Upgradable

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 upgradable* AV receiver, which not

only decodes Dolby Atmos, but also features three new speaker

configuration modes using overhead speakers—5.2.4-ch with

top forward/top backward (9.2-ch), 7.2.2-ch system with top

middle/front wide (9.2-ch), and 7.2.2-ch with top middle/front

height (9.2-ch). With 7.2.2-ch top middle/front wide and top

middle/front height, the top middle speaker is used for Dolby

Atmos content, and switches to front wide or front height when

playing other content.

What’s more, with the latest 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. You can fully appreciate the object effects

of Dolby Atmos with more clear and accurately positioned

theater sound.

* Firmware update required. Firmware update available by end of 2014.

Dolby TrueHD

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

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™

With DTS-HD Master Audio, you

can enjoy sound that is bit-for-bit

identical to the studio master.

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.
