A common feature of these models is that they can support the transmission of 8K/60Hz and 4K/ 120Hz ultra-high definition video signals through future software upgrades, and can realize a series of new functions of HDMI 2. 1 optimized for games, including ALLM, VRR, QMS and QFT.
Next, we will focus on the technical advantages and audio features of RX-A6A, aiming at the mid-to-high-end market of 20,000-30,000 yuan.
Dig into the key hardware chips of RX-A6A, Qualcomm QCS407, ES9026PRO and ES9007S.
Although from the current technical hotspots, many people will focus on the technical support of 8K and HDMI 2. 1 related videos, if you are not a hardcore gamer, your needs are mostly audio and video. In fact, RX-A6A basically supports 4K/60p and HDR 10 transmission in video at this stage, which can meet more than 90% applications. You can wait for the future.
In my opinion, RX-A6A is the core hardware chip of audio, Qualcomm QCS407 SoC, and two ESS high-performance ES9026PRO and ES9007S DAC audio digital-to-analog converters.
First, let's take a look at the core of RX-A6A audio processing-the system-on-chip of Qualcomm QCS407 SoC. QCS407 belongs to the flagship SoC of QCS400 series released by Qualcomm 20 19. It is specially designed for AV amplifiers, strip speakers and smart speakers. It has a 4-core processor, two DSPs and Qualcomm Adreno GPU, and an integrated AI processing engine, which can support up to 32 audio outputs.
Qualcomm QCS407 SoC with quad-core processor, dual DSP and AI processing engine can be said to be the core of audio and video processing in RX-A6A.
This performance configuration is quite strong even at 202 1. It can be said that Qualcomm QCS407 provides a solid hardware performance foundation for RX-A6A in surround sound processing, enabling it to fully support Dolby Atmos and DTS:X three-dimensional sound effects, as well as high-speed surround sound: AI real-time sound field optimization. AURO-3D sound effects can be supported through firmware upgrade in the future.
RX-A6A has a variety of system construction methods. It is worth noting that 1 1 channel 7.2.4 is built by an external power amplifier.
Next, let's take a look at the ES9026PRO and ES9007S used for RX-A6A in audio DAC. Among them, I pay special attention to the 32-bit processing power of ES9026PRO, which has the compensation function of ESS patented Hyper Stream and THD, and can greatly reduce the noise. ES9007S is also an excellent audio DAC with high signal-to-noise ratio and dynamic range of 120dB. Although this DAC configuration is not as luxurious as the high-end RX-A8A dual ES9026PRO, it still has certain advantages compared with the same class.
RX-A6A adopts the combination of ES9026PRO and ES9007S DAC, while RX-A4A has only one es907s DAC. On the contrary, the RX-A8A with higher positioning is a dual ES9026PRO configuration, and it can be clearly seen that Yamaha has three merging machines.
DSP digital sound field processing technology is getting better and better. I recommend you to turn on SURROUND:AI.
In 20021year, RXA6A has been equipped with a new generation of cinema DSP HD3, including the DSP parameter mode of 1 1 music performance scenes, such as the hall of Munich Concert Hall, the hall of Vienna Concert Hall, and the new york Jazz Club, a pioneer in rural areas. 12 DSP parameter modes of movies and games, such as role-playing games, adventure movies, drama musicals and comedies.
The unique feature of RX-A6A is that a set of dual-channel interfaces with balanced input and output are reserved on the back, which not only allows players to connect to a special Hi-Fi system, but also serves as an extension of the 7.2.4 system.
However, for many audio-visual enthusiasts, the more attractive place of RX-A6A is actually quite enjoyable surround: AI real-time sound field processing technology. This year, with the powerful 64-bit processing capability of Qualcomm QCS407, RX-A6A adopts a new generation of surround: AI real-time sound field processing function, with faster and more efficient sound processing capability.
When SURROUND:AI is turned on, RX-A6A can perform real-time automatic processing according to different program sources to optimize dialogue and background sound effects in different sound scenes. Surround: AI is really a rare good thing for movies that need to change scenes frequently.
Building 7.2.4 system, an impressive sense of space reappears.
Considering that the surround sound system used in our audio-visual room can reach the configuration of 9.2.6 at most, in order to give full play to the processing efficiency of RX-A6A, a 7.2.4 surround sound system is specially constructed with a 3-channel high-power amplifier. Before the test, the indoor sound field was measured and corrected by Yamaha YPAO-R.S.C system. During the test, the surround: AI function is turned on all the way.
Find the button on the quotAI quot remote control to open the SURROUND:AI function, and the logo of SURROUND:AI will light up on the right front of the fuselage. Surrounding: AI can analyze the scene in real time, focusing on sound elements, such as "dialogue", "background music", "ambient sound" and "sound effect", and optimize the scene in real time to create a realistic feeling.
Compared with the sense of space, the sound details presented by RX-A6A have been significantly improved in the early Yamaha home theater power amplifier, especially in environmental sound effects and audio-visual positioning. If you are a user of the older generation Yamaha home theater amplifier and want to better experience the advantages of immersive 3D sound effects such as Dolby Panorama and DTS:X, RX-A6A can be said to be a pretty good upgrade choice.
In terms of sound style, Yamaha's voice is light and agile, full of musical sense, which is very suitable for listening to concerts, operas and music-related programs. As for the sound performance in movies, we don't pursue too strong low frequency, but pursue the sound effect restoration of movies with a sense of positioning and impact.
For different DSP modes, we can also enter the menu for fine-tuning, including DSP intensity, delay, room size, activity, reverberation time and so on.
Facing the special home audio-visual market environment of chip shortage, it is not easy for us to choose a suitable home theater amplifier. Yamaha RX-A6A is not only a 9.2-channel home theater amplifier, but also a 7.2.2 or 5.2.4 immersive three-dimensional sound system, which can be extended to the common mainstream configuration of 7.2.4 through the front-stage output. In the future, it can be upgraded to support 8K/60p, 4K/ 120p and Ono -3D sound effects, plus unique surround: artificial intelligence and movies.
