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 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
89 87 85 82 81
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.
