Description of sound mode types

Dolby Surround

This mode uses Dolby Surround Upmixer to extend various sources to natural and realistic multi channels for playback. Use ceiling speakers such as top middle speakers to realize a three-dimensional sound field.

Dolby Digital

This mode can be selected when playing sources recorded in Dolby Digital.

Dolby TrueHD

This mode can be selected when playing sources recorded in Dolby TrueHD.

Dolby Digital Plus

This mode can be selected when playing sources recorded in Dolby Digital Plus.

Dolby Atmos∗

This mode can be selected when playing back content encoded with Dolby Atmos.
It decodes Dolby Atmos content and its positioning data in real time and outputs audio from the appropriate speakers, creating natural audio images regardless of the speaker layout. Use ceiling speakers and Dolby Atmos Enabled speakers to realize a three-dimensional sound field.

DTS Surround

This mode can be selected when playing sources recorded in DTS.

DTS ES Dscrt6.1∗1

This mode is suitable for playing discs recorded in DTS-ES.
The surround back channel added using the discrete method is played as an independent channel.
Since all channels are independent, the 360-degree spacial expressiveness and sound localization are enhanced.

DTS ES Mtrx6.1∗1

This mode is suitable for playing discs recorded in DTS-ES.
The surround back channel added to the surround-left and surround-right channels by a matrix encoder at software recording time is decoded by this unit’s matrix decoder and played from each channel (surround left, surround right, surround back).

DTS 96/24

This mode can be selected when playing sources recorded in DTS 96/24.

DTS-HD

This mode can be selected when playing sources recorded in DTS-HD.

DTS Express

This mode can be selected when playing sources recorded in DTS Express.

DTS:X

This mode can be selected when playing back content encoded with DTS:X.
It decodes DTS:X content and its positioning data in real time and outputs audio from the appropriate speakers, creating natural audio images regardless of the speaker layout. Use height speakers to realize a three-dimensional sound field.

DTS Neural:X

This mode uses DTS Neural:X Upmixer to extend various sources to natural and realistic multi channels for playback.
Use height speakers such as front height speakers to realize a three-dimensional sound field.

DTS Virtual:X∗2∗3

This mode uses DTS Virtual:X with virtual height and virtual surround processing to realize a three-dimensional sound field when the height speakers are not used.

Auro-3D

This mode uses an Auro-3D decoder to create three-dimensional audio output using the Height Channel. It is ideal for playback of signals encoded as Auro-3D with a Height Channel. If signals not encoded as Auro-3D are input, an Upmixer called the Auro-Matic is used to create highly realistic three-dimensional audio output.

Auro-2D Surround

This mode uses an Auro-3D decoder to create Surround Sound without a Height Channel. It is ideal for playback of signals encoded as Auro-3D without a Height Channel. If signals not encoded as Auro-3D are input, an Upmixer called the Auro-Matic is used to output Surround Sound.

Multi Ch In

This mode can be selected when playing multi-channel PCM/DSD sources.

Multi Ch Stereo

This mode is for enjoying stereo sound from all speakers.

Virtual

This mode lets you experience an expansive surround sound effect when playing back through just the front (L/R) speakers only, and when listening with stereo headphones.

Auto

In this mode, the type of digital signal input, such as Dolby Digital, Dolby TrueHD, Dolby Digital Plus, Dolby Digital EX, Dolby Atmos, DTS, DTS-HD, DTS:X, DTS-ES, PCM (multi-channel) is detected, and the playback mode switches automatically to the corresponding mode.
If the input signal is analog or PCM (2-channel), stereo playback is used. For Dolby Digital or DTS, the music is played back according to the respective channel number.

Stereo

This mode plays 2-channel stereo audio with no additional surround sound processing.

Direct

This mode plays back audio as recorded in the source.

Pure Direct

This mode plays back an even higher quality sound than the “Direct” mode.
The following circuits are stopped in order to further improve sound quality.
