After the popular Yamaha RX-A2A launched last November, the Japanese manufacturer has expanded its range of Yamaha Aventage A/V receivers with the Yamaha RX-A4A, Yamaha RX-A6A and Yamaha RX-A8A. These new UHD 4K/120Hz and 8K receivers take the design and amplification technology of the first representative of the Yamaha RX-A series, while bringing an even more high-end design, with a processor and a DAC that are more powerful than ever.
The Yamaha RX-A4A, Yamaha RX-A6A and Yamaha RX-A8A receivers from the Aventage 2021 range represent the best of the Japanese manufacturer’s A/V receivers. Like the Yamaha RX-V4A and Yamaha RX-V6A models, as well as the Yamaha RX-A2A, they adopt a design that is a departure from previous generations of Yamaha AV receivers. They have a much more modern and understated look, with a black mirror front panel equipped with a large central volume control as well as a new LCD screen offering a higher resolution and visibility. The control interface has also had a facelift with touch-sensitive buttons for the main controls and control of the MusicCast multi-room functions.
UHD 4K/120Hz and 8K/60Hz
With the arrival of the Xbox Series X and PlayStation 5 game consoles with HDMI 2.1, the whole world of video games, but also that of multimedia interfaces, has been turned upside down. So naturally, the new Yamaha RX-A4A, Yamaha RX-A6A, and Yamaha RX-A8A have seven HDMI ports that support 4K/120Hz and 8K/60Hz, with support for VRR (Variable Refresh Rate), ALLM (Auto Low Latency Mode), QMS (Quick Media Switching), and QFT (Quick Frame Transport) gaming features so that the TV can adjust its settings in real time. The HDMI inputs/outputs are also compatible with the main HDR (High Dynamic Range) formats: HDR 10, Dolby Vision and HLG (Hybrid Log-Gamma). Finally, there are three HDMI outputs on these receivers, thus allowing the connection of several players. The main output is eARC/ARC compatible to retrieve the sound track of the program viewed on the associated television or projector.
Regarding audio, there are 7.2 channels on the Yamaha RX-A4A, 9.2 channels on the Yamaha RX-A6A with decoding and pre-amplification up to eleven channels and 11.2 amplified channels on the Yamaha RX-A8A, the flagship model of the range. Under hi-fi conditions, the Yamaha RX-A4A and Yamaha RX-A6A are rated at 110 watts and the Yamaha RX-A8A at 150 watts. This power is provided by the high-sweep amplification technology already used in the Yamaha RX-A2A. The latter optimizes the responsiveness and dynamics of the reproduction, while limiting unwanted noise.
Of course, the new Yamaha RX-A receivers are compatible with the latest audio formats, including Dolby Atmos and DTS:X. In addition, they benefit from a new Qualcomm 64-bit processor offering superior processing power, which allows Yamaha to make the most of its new DSP Surround AI technology. This technology is able to analyze the soundtrack in real time to apply the most suitable mode, from a selection of more than 24 DSP programs. The processing power also benefits YPAO calibration, which can provide more accurate 3D measurements than ever before, as well as stereo virtualization.
Multi-room & streaming
Like the brand’s previous models, these Yamaha receivers benefit from proprietary Yamaha MusicCast technology. This allows you to create a multi-room system by grouping MusicCast-compatible equipment in different rooms of a house or apartment. It is then possible to listen to the same song in all the zones or on the contrary a different song in each zone. It is even possible to use Yamaha MusicCast 20 and Yamaha MusicCast 50 speakers as wireless surround speakers, but also the Yamaha MusiCast SUB 100 wireless subwoofer.
MusicCast technology also opens the door to countless online music services like Qobuz, Deezer, Spotify, TIDAL, Amazon Music and thousands of internet radio stations. These services are accessible via the free MusicCast app, just like audio files shared in DLNA on the home network. This playback of files shared over the local network is possible up to 32-bit/384kHz and DSD 11.2 Mhz thanks to the use of new DACs: ESS SABRE9007S for the Yamaha RX-A4A and ESS ES9026PRO for the Yamaha RX- A6A and Yamaha RX-A8A. We therefore gain more versatility and precision compared to the Yamaha RX-A2A, which is limited to 24-bit/192kHz in PCM.
With the Yamaha RX-A4A, Yamaha RX-A6A and Yamaha RX-A8A, the Japanese manufacturer is looking to the future by offering A/V receivers that are compatible with UHD 4K/120Hz and UHD 8K to accommodate the most recent sources, televisions and video projectors. These four models are now available for pre-order at the respective prices of €1,699 for the Yamaha RX-A4A, €2,799 for the Yamaha RX-A6A and €3,999 for the flagship Yamaha RX-A8A.
