AllCh Stereo
This mode is ideal for background music. Stereo sound is played through the
surround speakers as well as the front speakers, creating a stereo image.
Direct
This listening mode can be selected for all input signals. Processing that a󰀨ects
sound quality is shut down, and sound closer to the original is reproduced. The
sound is reproduced with the sound eld based on the number of channels in the
input signal. For example, a 2 ch signal is output only from the front speakers.
Note that the sound adjustment is not available when this mode is selected.
Atmos
(Firmware version before supporting Atmos 2.0, etc.)
Selectable at the time of inputting Dolby Atmos audio format when height
speakers are connected. This mode faithfully reproduces the stereophonic sound
design recorded in the Dolby Atmos audio format.
Unlike existing surround systems, Dolby Atmos does not rely on channels, but
rather enables the accurate placement of sound objects that have independent
motion in a 3D space with even greater clarity. Dolby Atmos is an optional
audio format for Blu-ray Discs and achieves a more stereophonic sound eld by
introducing a sound eld above the listener.
To enable transfer of this audio format, connect via an HDMI cable and set the
audio output on the player to Bitstream output.
Atmos
(Firmware version supporting Atmos 2.0, etc.)
Since this mode calculates the positional data of audio recorded in Dolby Atmos
audio in real-time and outputs it from appropriate speakers, you can enjoy the
natural and stereophonic sound eld of Dolby Atmos with any speaker layout
including connection of only front speakers. Also, the Dolby Atmos sound design
can be reproduced more faithfully by connecting height speakers. You can select
this mode when inputting the Dolby Amos audio format.
