Yamaha RX-A4A: 7.2-Channel AV Receiver with SURROUND:AI and 8K/4K for Ultimate Immersion

The Yamaha RX-A4A is a premium AV receiver meticulously engineered to deliver a truly immersive audio and visual experience, transporting you directly into your favorite movies, music, or games. Central to its amazing sound performance is the **SURROUND:AI™** technology, which analyzes the scene content in real-time, optimizing the surrounding sound effects for distinct audio elements like background music, dialogue, and sound effects. This provides a finely tuned sound field akin to having a professional sound engineer adjust the audio on a scene-by-scene basis. Moreover, the receiver features exquisite craftsmanship, including the newly designed Anti Resonance Technology (A.R.T.) with an H-shaped cross frame and rock-solid mechanical structure. This construction effectively prevents internal and external vibrations that can compromise sound quality, allowing you to experience crystal-clear audio that truly stirs your emotions while the AV receiver itself remains perfectly still.

• 8K/60Hz and 4K/120Hz Support: Supports the latest HDMI technology for the highest resolutions and refresh rates, delivering smoother, more realistic visual experiences for movies and competitive gaming.
