Dolby Atmos

LX901 LX801 LX701 LX502

Dolby Atmos is a unique new

technology for enjoying the latest

surround sound. In a movie cinema, 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 cinema'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 localisation

and movement.

This cinema sound experience can be reproduced in your home

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

Dolby Atmos, but also supports maximum 7.2.4ch* speaker

system.

What's more, with the MCACC 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 calculates the

reflex path distance and also 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.

* For details on each model, check the speaker configurations on page 17-20.

Dolby Surround

LX901 LX801 LX701 LX502

The new surround sound effectively up-mixes legacy channel-

based content for reproduction on a Dolby Atmos environment,

expanding the original source to fill the speaker layout of a

Dolby Atmos system.

Dolby TrueHD

LX901 LX801 LX701 LX502

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 cinema experience like never before.

Loudness Management

Loudness Management frees you from annoying volume

fluctuations that often occur when switching channels,

programmes, 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:X

LX901 LX801 LX701 LX502

DTS:X is the next-generation audio codec from

DTS that leverages object-based audio to

enable new immersive and interactive audio

experiences. Since DTS:X can automatically adapt the audio to the

existing channels and speaker system, no specific speaker layout is

required. Experience an immersive soundscape with incredibly rich

and life-like audio. The format is backward compatible with DTS-

HD Master Audio, so you can also give new life to your movie

collection. With the ideal reproduction environment created by

MCACC, and the powerful and precise multi-channel output by the

Direct Energy HD Amplifier, the Pioneer AV receivers maximise the

advantages of the DTS:X format.

Dialogue Control

The feature lets you independently control the volume of

dialogue—a useful feature for people hard of hearing, or for

late-night movie viewing.

DTS Neural:X

LX901 LX801 LX701 LX502

DTS Neural:X is the latest down/up-mixing and spatial remapping

technology built into DTS:X. It provides an up-mx of Neural:X-

encoded and non-encoded (PCM) data and can produce up to 11.x

channels, letting you enjoy a more realistic atmosphere

regardless of the original audio format.
