Yamaha RX-A8A 11.2 Channel AV Receiver

Home cinema, perfected. The A8A is the top of the AVENTAGE line, making it the best of the best. Experience room-filling sound and crystal-clear picture with this innovative AV receiver.

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.

SURROUND:AI™

Artificial intelligence (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 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 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 of up to 11.1 channels is possible* even with a 7.1-channel speaker configuration.

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®

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 favourite movies.

AURO-3D

The magic of AURO-3D® technology lies in the ability to transform any space and any content. AURO-3D will deliver a purely transformative, breath-taking immersive audio experience, every time. The unique, vertical stereo field of AURO-3D allows sound to move around you, similar to how it does in your everyday life, ensuring a powerful soundscape that transports us into the world of our chosen content. Escape into the story and get lost in the music. Experience every moment and emotion the way nature intended. Hear more, feel more with AURO-3D.

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 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.

It features ESS’s state of the art 32-bit SABRE PRO Premier DAC ES9026PRO. ESS’s patented 32-bit Hyper Stream, Total Harmonic Distortion (THD) compensation function works to minimize noise levels. In combination with the Yamaha original D.O.P.G. (DAC On Pure Ground) concept, which eliminates the potential difference between audio circuit stages to reduce ground noise, it dramatically enhances silence and resolution over the entire audio range for rich and expressive reproduction of even the most delicate sounds.
