Part of the prestigious Aventage range, this 7.2-channel model delivers an immersive audiovisual experience and exceptional performance for demanding movie and music enthusiasts. Equipped with the latest audio and video processing technologies, the RX-A4A stands out as a benchmark on the home cinema amplifier market.
Controlled power for breathtaking sound reproduction
The heart of the Yamaha RX-A4A lies in its high-quality amplification. With a power output of 110 W per channel (at 8 ohms, 20 Hz – 20 kHz, 0.06% THD, 2 channels), this amplifier delivers sound reproduction that is both powerful and precisely controlled. The high-speed amplification technology optimizes responsiveness and dynamics, ensuring faithful reproduction of even the most demanding soundtracks.
The RX-A4A’s amplification architecture has been completely redesigned for this new generation. It features carefully selected high-end components and Yamaha’s Total Purity Concept technology, guaranteeing flawless sound quality. This design enables the amplifier to respond instantly to the dynamic swings of soundtracks, thus reproducing all the richness and complexity of modern audio mixes.
Total sound immersion with the latest audio formats
The Yamaha RX-A4A doesn’t stop at high-quality amplification. It also features a cutting-edge audio processor capable of decoding the latest sound formats. Compatible with Dolby Atmos and DTS:X, this amplifier plunges you into the heart of the action with enveloping three-dimensional sound. Sound effects come from all directions, including overhead, for a truly immersive cinematic experience.
In addition to object-based formats, the RX-A4A supports a wide range of other audio codecs, ensuring optimal compatibility with all types of content. Yamaha’s exclusive SURROUND:AI technology analyzes the different sound elements (dialogue, music, effects) in real time to automatically create the most suitable sound field for each scene. This intelligent function constantly optimizes audio rendering for maximum immersion, whether you’re watching films, TV series, or playing video games.
Breathtaking images: next-generation video
The Yamaha RX-A4A is also impressive when it comes to video processing. Equipped with seven HDMI 2.1 inputs, it is fully compatible with the latest video standards, including 4K at 120 Hz and 8K at 60 Hz. Support for HDR10+ and Dolby Vision ensures exceptional image quality, with striking contrast and vivid colors.
Gamers will particularly appreciate the features dedicated to video games.

Compatibility with these cutting-edge technologies makes the RX-A4A an ideal choice for both movie lovers and demanding gamers.
Precision acoustic calibration for optimal performance
To get the most out of your home cinema setup, the Yamaha RX-A4A includes the YPAO (Yamaha Parametric Room Acoustic Optimizer) acoustic calibration system. This advanced technology uses the supplied microphone to analyze your room’s acoustics and automatically adjust the amplifier’s settings accordingly.
The YPAO calibration process harnesses the power of a 64-bit Qualcomm processor to perform precise 3D measurements of your listening environment. It optimizes frequency response, phase, and any acoustic delay of each speaker, ensuring sound reproduction that perfectly matches your space. Thanks to this technology, you enjoy optimal sound, whatever the layout of your room.
Seamless connectivity for a complete multimedia experience
The Yamaha RX-A4A is not just outstanding for home cinema. It also offers extensive connectivity to meet all your multimedia needs. Equipped with wireless Wi-Fi, Bluetooth, and Apple AirPlay 2 technologies, it lets you easily stream music from your mobile devices or home network.
The amplifier includes many popular streaming services such as Qobuz, Deezer, Spotify, TIDAL, and Amazon Music. You also have access to thousands of free Internet radio stations. All these features are accessible via Yamaha’s MusicCast app, which offers an intuitive interface to control your entire audio system.
DLNA compatibility allows playback of audio files shared on your local network, with support for high-resolution formats up to 32-bit / 384 kHz for PCM streams and 11.2 MHz DSD. This versatility makes the RX-A4A a true hub for all your audio content, whether stored locally or streamed.

I switched from a DENON AVR 1700 to this model after doing quite a bit of research. I wanted to improve the quality of stereo hi-fi listening while keeping a good home theater system. It’s the perfect model at a still-reasonable price. Your CDs or vinyl records will thank you (well, your ears will), and it’s great for home theater too. I use this amp with FOCAL Aria EVO 3 speakers.

Je suis passé d'un DENON AVR 1700 à ce modèle après plusieurs recherches. Je voulais augmenter la qualité des écoutes HIFI Stéréo tout en gardant un bon système cinéma maison. C'est le modèle parfait à prix encore raisonnable, vos CD ou vinyles vous diront merci (enfin vos oreilles) et pour le ciné à la maison c'est parfait aussi. Pour ma part je suis sur les FOCAL Aria EVO 3 avec cet ampli.

Really great amp to replace my Yamaha RXV6. AI mode is impressive for adding immersion and depth to home theater. I paired it with a Tonewinner 2500 pro via the front pre-out output to power Klipsch RF7 speakers. Very easy setup with YPAO and AirPlay 2 function (I use it with SONOS SL speakers in party mode with friends Beware, it is bulky Great, non-aggressive sound

Ampli vraiment top en remplacement de mon Yamaha RXV6.
Le mode AI est bluffant pour donner de l’immersion et du relief en home cinéma.
Je l’ai couplé à un Tonewinner 2500 pro sur la sortie pré out front pour alimenter des Klipsch RF7.
Les réglages avec YPAO très facile et fonction AirPlay 2 ( je le fait fonctionner avec des SONOS SL en mode soirée entre amis
Attention il est imposant
Son top et pas agressif
