The Yamaha RX-A4A is a high-performance 7.2-channel A/V receiver from Yamaha’s premium AVENTAGE lineup, built to deliver immersive home theater audio and flexible modern connectivity. It combines powerful surround sound, advanced room tuning, and the latest video features to elevate movies, music, and games.
This receiver offers 7 channels of amplification with around 110 watts per channel (into 8 ohms) to drive a wide range of speaker setups, including traditional 5.1 systems and more immersive formats such as Dolby Atmos and DTS:X. It supports surround processing technologies like Yamaha’s proprietary SURROUND:AI and CINEMA DSP HD3, which automatically analyze audio content in real time and adjust sound fields for a more enveloping, realistic experience.
For video, the RX-A4A includes multiple HDMI inputs and outputs with full 8K/60Hz and 4K/120Hz passthrough, plus support for HDR formats such as HDR10+, Dolby Vision, and Hybrid Log-Gamma, making it capable of handling today’s highest-resolution sources and next-gen gaming consoles.
Connectivity is modern and versatile, with Wi-Fi, Bluetooth, AirPlay 2, and MusicCast multi-room streaming, letting you easily stream audio from smartphones, services, or networked devices. Voice control with Alexa, Google Assistant, and Siri (via AirPlay 2) adds convenience, while integration with Sonos systems and network control features make it suitable for larger, connected audio setups.
The receiver also features Yamaha’s YPAO-R.S.C. room calibration, which measures room acoustics and tailors the sound for optimal performance. Extra features like Zone 2 support, a phono input for turntables, and broad file format support enhance flexibility for both music and home cinema use.
