SOUND FIELD MODE
STRAIGHT Plays the sound without applying the sound field effect.
CINEMA
Gives a greater sense of immersion and presence to movies with action scenes, such as action and
SF movies. The effect increases the separation between dialogue and sound effects or background
music.
DRAMA
Lets you comfortably enjoy animated shows, dramas, variety shows and other content where
voice is important.
The effect increases the separation between dialogue and sound effects or background music,
making the dialogue sound more real and adding a comfortable sense of reverberation.
MUSIC VIDEO
Simulates a comfortable spatial placement of vocals and musical instruments, for enjoying music
videos and other content.
This creates a pleasant sense of space and sonic placement.
CONCERT HALL
A setting that creates the echoes and space of a live concert in a hall, letting you enjoy the
performance as if you were part of the venue.
This creates a sense of envelopment, enthusiasm, unity and realism.

OUTDOOR LIVE
Recreates the open-air feeling of an outdoor setting, letting you enjoy the sense of watching a live
performance outdoors.
This creates a sense of unity, openness and realism, reproducing a unique outdoor space by
keeping the reverberations to an appropriate level.
BGM
This setting is suitable for listening to background music where the sound is localized outside the
head, letting you relax and listen to music.
Uses Yamaha’s proprietary high-definition HRTF (Head Related Transfer Function) technology to
process the stereo position of the sound outside your head.

Setting the DAC filter
This shows how to change the type of digital filter used by the DAC (Digital to Analog Converter), for adjusting
the sound quality to your preferences.
Setting menu
“DAC FILTER”
Settings
FAST LINEAR Uses a steep filter to remove noise from outside the desired frequency band. The resulting sound
quality tends to be clear.
SLOW LINEAR Uses a gentle filter to remove noise from outside the desired frequency band. The resulting sound
quality tends to be more gradual with a softer attack.
FAST MINIMUM Removes noise from outside the desired frequency band with a steep filter. This gives a clear tone,
and the resulting sound quality tends to have a more powerful low end than FAST LINEAR.
SLOW MINIMUM Removes noise from outside the desired frequency band with a gentle filter. The resulting sound
quality tends to have a sharper attack than SLOW LINEAR, with a powerful low end.
APODIZING FAST Removes noise from outside the desired frequency band with a filter that has less pre-ringing than
FAST LINEAR. The resulting sound quality tends to be clear and transparent.
HYBRID FAST
Removes noise from outside the desired frequency band using a special filter with both linear
phase and minimum phase. The resulting sound quality tends to have a sharper attack with a
powerful, crisp sound.
BRICKWALL Removes noise from outside the desired frequency band by using a filter with steeper
characteristics than all the others. The resulting sound quality tends to be clear in the high end.
SHORT LATENCY
An original digital filter by Yamaha. Removes noise from outside the desired frequency band with a
filter that reduces the amount of pre-ringing, minimizing filter-based latency. The resulting sound
quality of this filter tends to have a sharper attack with a rhythmical feel.
Default setting
