The Benchmark for AV Receivers
AVENTAGE AV receivers are the reference standard to which all others are compared. Passionate engineering and meticulous attention to detail produce the Yamaha hallmark of True Sound. You can feel the quality in the design and fabrication – from every electrical path, component and piece of material. Each element was scrutinized with intense detail to produce the finest, first-class performance. The AVENTAGE AV receiver is a work of visual and acoustic art.
Artificial intelligence (AI) technology built into the DSP analyzes the scene of the entertainment content and then creates the optimal surround effect to reproduce it with the ultimate impact. This AI instantaneously analyzes 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 listening right next to you, 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.
Cinema DSP HD3 for Movie, Music and Games
This Yamaha flagship 3D sound field playback technology was created by combining actual measured sound field data with cutting edge digital signal processing technology. The revamped CINEMA DSP HD3 features new signal processing algorithms and maximizes theater 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, center and surround speakers to create a rear virtual speaker, CINEMA DSP HD3 playback of up to 11.1 channels is possible* even with a 7.1-channel speaker configuration.
*Requires connection to a front presence speaker.
Dolby Atmos® and Dolby Atmos Height Virtualization
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.
For those without in-ceiling or upward firing speakers in their system, Dolby Atmos Height Virtualization technology can simulate the Atmos experience. 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.
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.
Compressed Music Enhancer
When music is encoded into a digitally compressed format like MP3, the frequency response suffers. The Yamaha 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.
HIGH QUALITY PARTS
High Slew Rate Amplifier
The slew rate measures how quickly an amplifier can respond to a rapid change of input level, which contributes to delivering a precise signal transmission and is especially effective with high resolution audio signals. This newly designed circuit achieves both a high slew rate and stable signal transmission, allowing it to handle each audio signal with precision and accuracy.
High-Quality Digital Components
The 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.
Anti-Resonance Technology Wedge
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.
Newly Designed Mechanical Structure
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 clearer, sharper and more 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.
