Listening Mode Effects
In alphabetical order
„
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.
„
Atmos
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 field 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 surround back speakers or
height speakers. You can select this mode when inputting 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 field by
introducing a sound field above the listener.
According to the speaker layout, the following listening modes are displayed.
– Atmos 2.0/2.1 : When only front speakers are installed
– Atmos 3.0/3.1 : When front speakers and center speaker are installed
– Atmos 4.0/4.1 : When front speakers and surround speakers are
installed
– Atmos 5.0/5.1 : When front speakers, center speaker and surround
speakers are installed
– Atmos 6.0/6.1 : When front speakers, surround speakers and surround
back speakers are installed
– Atmos 7.0/7.1 : When front speakers, center speaker, surround speakers
and surround back speakers are installed
– Atmos 2.0.2/2.1.2 : When front speakers and height speakers are
installed
– Atmos 3.0.2/3.1.2 : When front speakers, center speaker and height
speakers are installed
– Atmos : Selectable in the "4.1.2 ch", "5.1.2 ch", "6.1.2 ch", "7.1.2 ch",
"4.1.4 ch" or "5.1.4 ch" setting with surround speakers and height speakers

increasing the number of channels and endeavoring to improve sound quality
by giving more flexibility in data bit rates. Dolby Digital Plus is an optional audio
format based on 5.1 ch for Blu-ray Discs. It is possible to record a maximum of
7.1 channels with additional channels such as the surround back channel.
