Description

 

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.

 

 

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 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.

 
 

New circuit achieves more than doubled slew rate and it would contribute a precise signal transmission, effective for high resolution audio signal. Generally high slew rate amplifier causes unstable signal transmission, Yamaha’s newly designed circuit achieves high slew rate with stable signal transmission.

 

Qualcomm® QCS407 is designed to provide truly superior audio performance, with support for Dolby Atmos and DTS:X immersive home audio, as well as a dedicated high-performance audio DSP.

Incorporating the SABRE ES9007S Premier Audio DAC from ESS Technology to achieve an exceptional signal-to-noise ratio and up to 120 dB of dynamic range, this AV receiver produces professional quality digital audio.

 

 

The newly designed Anti Resonance Technology (A.R.T.) Wedge is a fifth foot in the front-and-center of the chassis unit base. It dampens much more vibrations from the power transformer, power transistors and heat sinks, as well as vibrations that might be caused by the sound from the speakers — providing dynamic sound and focused, accurate reproduction.

 

 

The highly logical and symmetrical internal layout of parts and totally renewed circuit boards are designed to keep the signal paths on each board as short as possible. The new H-cross frame improves rigidity of the receiver body and sound stability, allowing for a more clear, sharp and transparent reproduction. Also the newly redesigned mechanical structure contributes to avoiding the transition of vibration from the transformer to the amplifier circuit. Sound noises are reduced to improve clarity.

 

 

HDR10+ signals not only dynamic range (the ratio of light to dark) of video content on a scene-by-scene (or even frame-by-frame) basis, it also provides, in a small amount of metadata, the scene characteristics between bright and dark so that important detail can remain. This enables displays to reproduce images more realistically, adhering to the creator’s intent.

 

 

Supports end-to-end 8K/4K resolutions and higher refresh rate solutions with a single upgraded cable for seamless integration within the HDMI eco-system.8K delivers a super-immersive viewing experience with 2x the horizontal and vertical resolution of 4K, and 4 times as many pixels; and combined with 60Hz refresh rate enables smooth and sharp viewing of content with high-speed action. 4K/120Hz enables ultra-fast motion UHD images to be crisp and razor sharp; allowing sports, action movies, high-performance gaming and VR to benefit significantly.

 

 

Enhanced gaming and media features ensure an added level of smooth and seamless motion and transitions for gaming, movies and video. They include: Auto Low Latency Mode (ALLM) enables the ideal latency setting to automatically be applied, allowing for smooth, lag-free and uninterrupted viewing and interactivity. Variable Refresh Rate (VRR) reduces or eliminates lag, stutter and frame tearing for more fluid and detailed gameplay.

*YAMAHA initially intended to support QMS (Quick Media Switching) within the HDMI 2.1 specification. However, YAMAHA later discovered that these models cannot be updated to support QMS via firmware. This is due to an unforeseen hardware limitation caused by QMS specification change in HDMI 2.1a. This hardware limitation affects current AV receivers, including Yamaha. (Information corrected in May 2023)

 

 

YPAO-R.S.C. (Reflected Sound Control) analyses the room acoustics with the included YPAO microphone to tune your system for the best sound in your unique room. It employs R.S.C. to correct early reflections for studio-quality surround sound. YPAO 3D provides automatic sound parameter optimisation that maximises the 3D sound field effectiveness of SURROUND:AI as well as Dolby Atmos and DTS:X. 64-bit high precision EQ calculation achieves the most natural room acoustics possible.

 

 

Combine this AV receiver with the MusicCast 50 or MusicCast 20 wireless streaming speaker and enjoy the amazing convenience of creating a home theatre with wireless surround sound. What’s more, you get stunningly realistic sound with a clean, clutter-free setup. Easily turn your current living room into a special entertainment environment where you can fully enjoy movies and music.

 

 

Use your smartphone or tablet together with the MusicCast CONTROLLER app to operate the AVR and change settings quickly and easily. The same Controller app functions as a remote control for all your MusicCast-compatible devices as well as full multi-room audio controls.

 

 

Touch or voice control – the choice is yours. Intuitively control a single MusicCast product or an entire whole-of-home system with ease using Alexa or Google Assistant and hear your home come alive.

*Availability of voice command control via Amazon Alexa and Google Assistant varies by region.

*A third party device is required to initiate voice commands.

 

 

No worries, no confusion. Use this special app to receive expert set up assistance for your AV receiver and source devices. It even guides you through various other settings such as speaker connections, TV and source device connections and power amplifier assignments.

 

 

Explore a world of music with music streaming services* built-in. Synchronizing your playlists and tracks from your smart phone or computer to the AV receiver, music streaming services make it impossibly easy to either listen to your favorites or discover new music.

*Music streaming service availability varies by region.
