Updating of listening modes
We plan to provide support for the Dolby Atmos audio
format through firmware updates for this unit. This means
that the selectable listening modes depend on the version
of firmware.
On firmware version before Dolby Atmos support
0 Dolby Pro Logic II-related modes can be selected.
On firmware versions supporting Dolby Atmos
0 You can select Dolby Atmos, Dolby Surround, and
Surround Enhancer. (Dolby Pro Logic II-related modes
cannot be selected after updating.) Also, when Surround
Enhancer can be selected, T-D (Theater-Dimensional)
cannot be selected.
In alphabetical order
AllCh Stereo
Ideal for background music, this mode fills the entire
listening area with stereo sound from the front, surround,
and surround back speakers.
Direct
This listening mode can be selected for all input signals.
Processing that affects sound quality is shut down so sound
closer to the original is reproduced. Speakers play the
sound field according to the number of channels in the input
signal, so there would be output from only the front
speakers for a two-channel signal, for example.
Dolby Atmos
This mode faithfully reproduces the sound design recorded
in the Dolby Atmos format.
The Dolby Atmos audio format has been implemented in
movie theaters equipped with the latest facilities and
enables a revolutionary sound experience in home
theaters. Unlike existing surround systems, Dolby Atmos
doesn't rely on channels, but rather enables the accurate

placement of sound objects that have independent motion
in a three-dimensional space with even greater clarity.
Dolby Atmos is an optional audio format on Blu-ray Discs
and achieves a three-dimensional sound field by
introducing a sound field above the listener.
0 To enable transfer of this audio format, connect via HDMI
cable and set audio output on the player to bitstream
output.
Dolby D (Dolby Digital)
This mode faithfully reproduces the sound design recorded
in the Dolby Digital format.
Dolby Digital is a multi-channel digital format developed by
Dolby Laboratories, Inc. widely adopted for use in movie
production. It is also a standard audio format on DVD-Video
and Blu-ray Discs. It is possible to record a maximum of 5.1
channels on a DVD-Video or Blu-ray Disc; two front
channels, a center channel, two surround channels, and
the LFE channel dedicated to the bass region (sound
elements for the subwoofer).
0 To enable transfer of this audio format, connect via digital
cable and set audio output on the player to bitstream
output.
Dolby D+ (Dolby Digital Plus)
This mode faithfully reproduces the sound design recorded
in the Dolby Digital Plus format.
The Dolby Digital Plus format is a revision based on Dolby
Digital, increasing the number of channels and endeavoring
to improve sound quality by giving more flexibility in data bit
rates. Dolby Digital Plus is used as an optional audio format
on Blu-ray Discs, based on 5.1 channels, but with additional
channels such as the surround back channel added for a
maximum of 7.1 channels.
0 To enable transfer of this audio format, connect via HDMI
cable and set audio output on the player to bitstream
output.
Dolby PL II (Dolby Pro Logic II)
This listening mode allows you to expand the playback

signal to 5.1 channels to suit the connected speaker
configuration when the input signal is 2 channel.
Broadening the sound field provides you with a seamless
sound with more depth and realism. Along with CD and
movie sources, games can also benefit from the vivid
sound localization. Choose from a mode ideal for movies
(Movie), a mode ideal for music (Music), and a mode ideal
for gaming (Game).
Dolby Surround
This listening mode allows you to expand input signals with
2 channels, etc., to multiple channels to suit the
configuration of connected speakers. Along with past
speaker setups, this is also compatible with playback
systems for Dolby Atmos that include Dolby speaker
technology.
Dolby TrueHD
This mode faithfully reproduces the sound design recorded
in the Dolby TrueHD format.
The Dolby TrueHD audio format is a reversible format
expanded based on the lossless compression technology
referred to as MLP, and it makes it possible to faithfully
reproduce the master audio recorded in the studio. Dolby
TrueHD is used as an optional audio format on Blu-ray
Discs, based on 5.1 channels, but with additional channels
such as the surround back channel added for a maximum
of 7.1 channels. 7.1 channels can be recorded using
96 kHz/24 bit, and 5.1 channels can be recorded using
192 kHz/24 bit.
0 To enable transfer of this audio format, connect via HDMI
cable and set audio output on the player to bitstream
output.
DSD
Mode suitable for playing sources recorded in DSD.
0 This unit supports DSD signals input through HDMI IN.
However, depending on the connected player, better
sound is possible when output from the PCM output of
the player.
