This high-performance receiver has excellent A/V processing, strong amplification, and superior room calibration. It is also vibration-damped. Yamaha’s excellent control app for your phone or tablet makes using the AVENTAGE RX-A4A very simple.
A 5.1.2 Dolby Atmos or DTS:XTM system, which consists of the conventional five speakers and subwoofer as well as two upward-firing or in-ceiling speakers for overhead effects, is best powered by the seven-channel RX-A4A.
The primary goal of Yamaha’s Aventage RX-A4A receiver is still to provide customers with the most adaptable home theater and multi-room options as well as the most immersive surround sound formats. The most recent Ultra HD TVs and Blu-ray players function flawlessly with this powerful receiver, which fully supports cutting-edge 8K and HDR+ (High Dynamic Range) video technology. However, their days seems to be numbered now that online streaming is a reality. With MusicCast wireless multi-room audio playback, you can stream music from a broad range of sources and listen to high-quality audio in your living room or any other room in your home.
You’ve decided to use five speakers in your home theater space? Drive speakers in a different room of the house, such as the kitchen or a bedroom, by using the other two power channels.
The RX-A4A was designed by Yamaha to work with cutting-edge video technologies. Its seven HDMI ports are all 4K/60Hz compatible, making them ideal for high-end sources like an Apple TV or a 4K Ultra HD Blu-ray player. (HDMI 2.1 functionality will be made available with a free firmware upgrade in the future.)
For iOS and Android tablets, the free AV Setup Guide app from Yamaha takes you through the connection process step-by-step. The straightforward yet sophisticated YPAO calibration system analyzes your speakers and the acoustics of your room using a setup microphone that is included in order to optimize the sound of your system. Your compatible mobile device becomes an incredibly practical Wi-Fi remote control thanks to the complete, customizable AV Controller app.
High slew rate amplifiers are now available in this Aventage model. The dynamics of the final sound are directly correlated with an amplifier’s slew rate, which measures how rapidly the amplifier can react to a sudden shift in the input signal. The more exactly it can replicate and maintain pace with the original source, the more detail it can capture from the source, producing a sound that is more dynamic and powerful. To put things into perspective, this Aventage AVR model’s slew rate has doubled compared to that of the previous generation and is now the same as the MX-A5200 power amplifier.
Enjoy a wide range of musical genres.
There are many choices available for playing music as well. Through Wi-Fi, Bluetooth, or Apple AirPlay 2, you may play music from your smartphone or tablet. Optionally, connect your turntable using the built-in phono input. Even high-resolution tracks can be played from a networked computer or USB thumb drive.
In addition, the Yamaha RX-A4A can play music wirelessly across many rooms when paired with other MusicCast components. photo: YAMAHA
