The items (parameters) that can be adjusted depend on the signal being input and the currently set sound mode. For details on the adjustable parameters, see “Sound modes and surround parameters” link.

Some setting items cannot be set while playback is stopped. Make the settings during playback.

“Surround Parameter” settings are stored for each sound mode.

Cinema EQ

Gently softens the upper treble range of movie soundtracks to reduce possible harshness and improve clarity.


On:	“Cinema EQ” is used.
Off (Default):	“Cinema EQ” is not used.

Loudness Management

This sets whether to output as specified in “Dynamic Compression” or output directly without compressing the dynamic range of audio recorded in the disc.


On (Default):	Outputs are given based on enabling the settings made in “Dynamic Compression” and “Dialog normalization function” link.
Off:	“Dynamic Compression” settings and “Dialogue Normalization” are disabled, and the signals on the disc are output as is.

“Loudness Management” can be set when Dolby Digital, Dolby Digital Plus, Dolby TrueHD or Dolby Atmos signal is input.

Dynamic Compression

Compress dynamic range (difference between loud and soft sounds).


Auto:	Automatic dynamic range compression on/off control according to source.
Low / Medium / High:	These set the compression level.
Off:	Dynamic range compression is always off.

“Dynamic Compression” can be set when Dolby Digital, Dolby Digital Plus, Dolby TrueHD or Dolby Atmos signal is input.

The default setting is “Off”. When the input signal is the Dolby TrueHD or Dolby Atmos source, the default setting is “Auto”.

This can be set when “Loudness Management” is set to “On”.

Low Frequency Effects

Adjust the low frequency effects level (LFE).

When “Input Mode” is set other than to “7.1CH IN”


-10 dB – 0 dB (Default : 0 dB)

When “Input Mode” is set to “7.1CH IN”


0 dB / +5 dB / +10 dB / +15 dB (Default: +10 dB)

For proper playback of the different sources, we recommend setting to the values below.

Dolby Digital sources : 0 dB

DTS movie sources : 0 dB

DTS music sources: -10 dB

Upgrade (Auro-3D)

Auro-Matic 3D Preset

Selects the Auro-Matic 3D Preset for fine tuning the Auro-3D experience to specific audio material.


Small:	Small is ideal for pop and chamber music or movies with a lot of dialog. (e.g. comedy)
Medium (Default):	Medium is best used on jazz music or typical movies and TV shows.
Large:	Large is ideal for recordings that were recorded in large spaces. (e.g. orchestral recordings or action movies with big explosions.)
Speech:	Speech is ideal for recordings which are mostly dialog (e.g. news broadcast), and that have virtually no inherent spatial information.

You can set this when the sound mode is set to Auro-3D.

This cannot be set if the input signal contains Auro-3D signals containing a Height channel.

Upgrade (Auro-3D)

Auro-Matic 3D Strength

Changes the level of the up-mixed channels in relation to the original input signal.
The value ranges from 1(no up-mixing) to 16(Maximum level, providing maximum effect).


1 - 16 (Default:10)

You can set this when the sound mode is set to Auro-3D.

This cannot be set if the input signal contains Auro-3D signals containing a Height channel.

Center Gain

Distributes the dialogue output from the center channel to the front left and right channels and widens the sound image in the front.


0.0 – 1.0

You can set this when the sound mode is set to DTS Neo:X.

The smaller the value, the more dialogue is concentrated on the center channel. The larger the value, the more dialogue is distributed to front left and right channels, and the more the sound image widens in the front.

Center Spread

Center spread expands the center channel signal to left and right front speakers to create a wider frontal audio image for the listener. It is optimized and designed primary for playback of stereo music content.


On:	Use “Center Spread”.
Off (Default):	Do no use “Center Spread”.

You can set this when sound mode is Dolby Surround.

Speaker Select

Makes settings for the speakers outputting sound.

When the sound mode is “DTS Neo:X”


Surround Back:	Sound is output from the surround back speakers.
Height:	Sound is output from the front height speakers.
Wide:	Sound is output from the front wide speakers.
Back/Height:	Sound is output from the surround back and front height speakers.
Back/Wide:	Sound is output from the surround back and front wide speakers.
Height/Wide:	Sound is output from the front height and front wide speakers.

This can be selected when using any of the surround back, front wide or front height speakers.

When the sound mode is the original sound mode


Floor (Default):	Plays back without height speakers.
Floor & Height:	Plays back with height speakers.
Front:	Plays back only with speakers in front of the surround speaker.
