YAMAHA RX-A4A
AV RECEIVER

SURROUND:AI™

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.

Dolby Atmos® with Height Virtualizer

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.

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.

8K/60Hz, 4K/120Hz

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.

SCENE Buttons with the Ability to Preset Songs and Stations

There are four SCENE buttons. You can preset them for different inputs, as well as a sound field program, Music Enhancer, HDMI output and more. The inputs can be set to specific sources, such as an FM or Internet radio station, a station on a streaming service, a USB device or a song on a PC or NAS (network). Once you have set the buttons, simply press one on the main unit or the remote control to power on the receiver and hear your desired music. The buttons can be re-set at any time.
