As we all know, the suo fan group is the most willing to spend money in the technology circle.
Regarding this matter, my cousin's colleague Ah Qiang is absolutely qualified to appear and say.
How enthusiastic is this guy? He's the kind of guy who's willing to buy the original Sony Xperia phone and buy it back as the main machine.
What is even more enviable is that a while ago, his family was renovated, and Ah Qiang happily took out 80% of the decoration model and built his living room into a full set of Sony audio-visual entertainment equipment "A House Happy House".
For example, Sony's BRAVIA big color TV, vinyl machine, PS5 game console, there are many, all arranged.
Ah Qiang also specially spent tens of thousands of dollars to buy a complete set of Sony echo wall equipment to come back to his big color TV to help him entertain.
After the arrangement is completed, it is probably like this. ▼
After my cousin saw him buy this echo wall, there was not a day when he didn't rush home from work.
This aroused the curiosity of the cousin.
Is it that this echo wall really improves the sound effect of the game and the movie so much, or does the one-sided faith bonus of the fans add points to it? Is it really necessary for normal people to buy one of this?
This guy is really not small
In order to answer these doubts in his cousin's heart, last weekend my cousin went to A Qiang's house and carefully experienced Sony's new echo wall.
I have to say that in practice, my cousin found that there are still many famous halls in it.
The Echo Wall set that Cuong bought this time is composed of an HT-A7000 main device, with a subwoofer and two rear surround speakers.
It is the one listed on the official website at 16970 yuan, in short, the kind I can't afford to buy. ▼
As soon as I sat down, he blew up with me how good this device was and why he didn't regret chopping it off.
The biggest reason he bought this whole set of equipment is because Sony pushed an upgrade package that can stimulate the product's own small universe on April 15 to its own HT-A7000 Echo Wall product.
After repeated questioning from my cousin, he and I introduced Sony to this black technology called 360 Spatial Sound Field Mapping Technology (360SSM).
The effect of this set of echo wall + rear surround + subwoofer surround after full, in the words of Ah Qiang, is "fully stimulating the potential of echo wall products".
The living room of The Qiang family is cramped enough, relying on a wave of micro-manipulation of 360SSM, you can build an ideal audio and video space.
These physical speakers can "split" into multiple phantom speakers, enveloping people in the surround "Sonic Junction" it has created.
And Sony's products are more free for the placement of the rear surround sound, compared with other products.
It doesn't need to be placed too precisely to create a cinema-level grand sound base.
In addition to the huge improvement in software, the unique black technology bonus of HT-A7000 in hardware is also a lot of effort.
My cousin counted back and forth, and the HT-A7000 was equipped with 11 horns, all of them energetic and skilled...
The HT-A7000 uses a 7.1.2 channel design, where the "7" represents a total of seven channel speakers on the echo wall.
"1" means that there is a set of woofer channels
(Yes, the HT-A7000 already has two subwoofers built in), and the "2" means that there are two channels that emit sound upwards.
To put it more simply, the two channels of "2" are the way the echo wall creates an "echo", and the sound bounces back into the human ear after being thrown into the ceiling, as if the sound is emitted from somewhere in the air.
However, poor friends who know Sony's products should know that Sodafa's products have never relied on simple stacking or machine sea tactics.
Returning to the exclusive 360SSM technology mentioned above, if you want to have a precise control of sound, you must rely on the combination of software and hardware and advanced algorithms.
Only by thoroughly eating the technology can we "send it out at once, and everyone is ready for it."
Good horses with good saddles, I want to make the echo wall look good while listening well, and the design of the speaker interior is also very exquisite.
Take the shape of the speaker, but it's hard to do a loudspeaker that you want to cram into such a long piece of equipment.
Therefore, Sony designed the speaker unit to be approximately rounded rectangular, which can obtain the maximum diaphragm area in the echo wall body with limited space.
The larger the diaphragm area, the higher the sound pressure level, the more abundant the volume, and the more realistic the sound.
In order to achieve a wrapped sound field experience, the speakers of the HT-A7000 also coordinate the relationship between the position and sound between each speaker, so that the transmission of sound is more accurate and comfortable.
Interestingly, when Sony's acoustic team designed the HT-A7000, it was found that some of the speakers that played sound into the ceiling and created a three-dimensional atmosphere may have run into the listener's ears without passing through the reflection of the ceiling.
In this way, the sound of "straight to give" is more, and the "echo" effect of the natural sound reflection will be much weaker.
To solve this problem, Sony integrated a vertical surround sound engine and S-Force Pro's front-facing virtual surround technology into the echo wall.
The former creates a more vivid and layered high soundstage, while the latter is designed to create a more accurate three-dimensional surround sound.
Interestingly, the vertical surround sound engine was originally built by Sony to the echo wall without upward sound speakers to create a soundstage effect.
Now it is used on the HT-A7000, which belongs to the double layer Buff that Sony has stacked an echo effect on the echo wall.
In some sound-rich films, this echo wall creates a wonderful feeling of sound lingering overhead or behind the head.
It scared me
Of course, coupled with Sony's veteran S-Force Pro front-facing virtual surround technology, the sense of premium created by multi-layer surround sound makes the sound effects of Dolby Atmos and DTS:X fully utilized.
What is the real high-end echo wall, black technology stacked up! ▼
In terms of connection, the HT-A7000 supports HMDI, Bluetooth, AUX, USB and other device interfaces, as long as you want, when you call, the other party's voice can be put out with the speaker.
The echo wall itself also has a display screen, which is clear and easy to read, and refuses to be blinded. ▼
In addition, the deep joint optimization of the HT-A7000 and Sony TV makes the operation experience of the echo wall in the Sony audio and video ecosystem very Nice.
Ah Qiang said that this set of echo wall to buy back, connected to their own X95J TV basically no effort, moving the remote control can automatically set the echo wall in the home sound field coverage.
And after the first setting, you can directly use the TV remote control into the setting menu to adjust the volume, sound mode and other options.
While watching the movie, Cuong's BRAVIA XR TV X95J has a mid-sound field sync mode that turns the TV into the HT-A7000's mid-channel when turned on.
Of course, this is also part of the 360 spatial sound field mapping technology. ▼
In general, this wave of blood under Ah Qiang is to build his living room into a video and audio space that most gamers and music lovers envy.
To put it bluntly, the HT-A7000 also specially supports 4K/120FPS pass-through technology, connect it to the PS5, there will be no sound delay, and it can fully match the high refresh rate screen.
At the same time, this subwoofer also supports Hi-Res high-resolution music, whether it is playing a game or watching a movie, playing a game, or listening to music, it can firmly hold you in the living room and enjoy the leisure time at home.
As a rational soup powder, this set of equipment is more practical than the holy relic "suo sixty thousand", and the motivation to recharge the faith is more practical, and the wallet is also friendly.
The key is that the product power of this thing is really hard enough, although it cannot be compared with the top professional imaging equipment, it can be immersed in the consumer products, the complete body of the HT-A7000 (echo wall + subwoofer + rear surround), which is no less than the experience of offline cinemas.
And all you need is to carry it home, plug it in, and tap the remote control with your finger.
According to the cousin's view, in the price of 10,000 yuan, Sony's home audio and video system is worth the money and has a certain competitiveness in the same price point products.
If your family has a big color TV like Ah Qiang, then the effect of this HT-A7000 is definitely a soaring experience.
Oh yes, Ah Qiang also reminded me that during the May Day period, Sony was still engaged in activities, and the echo wall of his same suit, the official website price is now nearly 1000 yuan cheaper, as long as 15990 yuan.
However, he does not regret that he bought early, in his words, buying echo wall to put at home is really "afterglow around the beam, buy early to enjoy", Suo Fan will never regret it.
