Make every night movie night. In fact, feel like you've entered the story. The Yamaha approach to tonal balance delivers incredibly detailed and accurate timbre in each voicing. Dynamism is found in the emotive contrast between the stillness and motion in the movie. The urgency and suspense between action scenes is palpable through the sound field that is created.

AI technology built into the DSP analyses the scene of the entertainment content and then creates the optimal surround effect to reproduce it with the ultimate impact. This AI instantaneously analyses scenes by focusing on distinct sound elements such as dialogue, background music, ambient sounds and sound effects, and automatically optimizes the surround effect in real time. Imagine having a Yamaha sound engineer right there whilst your listening, tuning the best sound live and specifically for you. AI technology creates a compelling sense of realism with expressive power beyond conventional sound field effects, giving you the most profound entertainment experience possible. Qualcomm® QCS407 with 64-bit high precision processing delivers precise surround sound.

Yamaha’s flagship 3D sound field playback technology was created by combining actually measured sound field data with cutting edge digital signal processing technology. The revamped CINEMA DSP HD3 features new signal processing algorithms and maximises theatre sound effects, accurately reproducing a new dimension of realism for a sound field with a rich sense of presence and no feeling of boundaries. By using front, centre and surround speakers to create a rear virtual speaker, CINEMA DSP HD3 playback up to 11.1 channels is possible* even with a 7.1-channel speaker configuration.

*Requires connection to a front presence speaker.

Dolby Atmos® with Height Virtualizer
For those without in-ceiling or upward firing speakers in their system, Dolby Atmos® with Height Virtualization Technology simulates the Atmos experience with forward facing-drivers. Configure up to five speakers to replicate the effect of two in-ceiling speakers, or utilize all seven channels to simulate the powerful effect of four overhead speakers.

Feel every dimension in Dolby Atmos®. Enjoy a 5.1 surround speaker system and two additional overhead speakers or two Dolby Atmos® elevation speakers, delivering dramatic overhead effects for truly enveloping audio – including Dolby Surround upmixer for legacy content.

DTS:X®
DTS:X immersive audio formatting places sound where it would naturally occur in space, creating life-like, multi-dimensional audio. The included spatial remapping engine of DTS Neural:X™ offers improved immersion and heightened realism in all your favorite movies.

When music is encoded into a digitally compressed format like MP3, the frequency response suffers. Yamaha’s Compressed Music Enhancer employs sophisticated digital signal processing using exclusive algorithms to restore what was lost, so the music always sounds the way it should.
