Sony TV supports central sound field - perfect Sony
Recently, with the increase of time at home, people's demand for entertainment in the family's living room continues to grow. For C position TV products in the living room, high picture quality has become one of the basic criteria for evaluating a good TV among many qualities, because the more realistic picture can make people enjoy watching. Another important factor in immersion in your home entertainment experience is a better life-like audio experience. In contrast, home audio and video products including speakers, the good partner of television, are becoming more and more interested by users.

| 360 SSM technology enables cinema-level surround sound without the need for a speaker |
Sony, which listens to users' voices and continues to enhance the performance of the king of audio and video, has achieved market renown with audio and video technology led by XR knowledge chips in TV products, and has used decades of experience and accumulation in audio: Technological upgrades and product innovations bring consumers an audio product experience High quality worth Sony.
After the flagship home audio and video system HT-A9 at the end of October last year, it was the first to carry Sony Spatial Sound Mapping technology (360 Spatial Sound Mapping, hereinafter referred to as 360 SSM), in mid-April this year, and also supported speakerphone Flagship HT-A7000 360 SSM technology through firmware upgrade. With this function, the two home audio and video systems can combine the audio and video experience of television to build more immersive 3D sound effects, allowing users to enjoy a cinema-level entertainment experience.

Like good sound effects in the scene, for home audio and video system products including sound bar, this cannot be done by stacking the speakers. Just like a wonderful and intoxicating symphony, it cannot be performed by the instruments of highly skilled solo musicians themselves, but requires harmonious interaction of different parts, coordination and coordination of conductors to deliver the moving resonance. harmony. Over 40 years of development in the audio field, Sony has bestowed a wealth of technology and experience accumulation, and has now built a full suite of Sony 360 spatial audio technology. For home audio and video systems, Sony achieves precise sound control and creates a balanced and comprehensive system by integrating unique audio technology, innovative product design with appropriate parameters, and the most innovative audio technology and hardware design.

| 360 SSM |
The HT-A9 and HT-A7000 are equipped with 360 SSM technology. By measuring the distance between the speakers and the audio to the ceiling, with the help of upward emitting speakers in the fuselage, the sound is projected upwards and the sound is reflected by the space walls and ceilings. The uniqueness of the space and multiple phantom amplifiers that create true-to-life sound in [Perfect Listening Position] allow the sound field to extend dramatically in all directions. Different from virtual surround sound technology (depending on auditory psychology, the effect varies from person to person), this technology creates a real sound field. For users, when they are in the wide sound field generated by 360 SSM, everyone is listening to C-bit, whether you are watching movies or playing games, you can experience realistic surround sound just as if you were in the content.
When the HT-A9, HT-A7000 and Sony TV form the same sound field system, the two home audio and video systems together can build a more immersive surround sound field based on the excellent sound quality of the TV. Both HT-A9 and HT-A7000 support central sound field synchronization mode * 1. Through joint optimization with Sony TVs, a natural match is achieved. After connecting to a BRAVIA TV that supports this function through the included cable, the TV will become the central channel of the home theater system, so that the sound can be accurately matched with the TV picture, making people feel like they are in a movie or game.
In addition, 360SSM technology combined with Sony's automatic sound field optimization function allows users to easily enjoy cinema-level surround sound without the need for precise positioning of the speaker, which solves the time-consuming and labor-intensive 'accurate positioning' of traditional audio products. Use pain points.
While implanting audio technology into the product, in order to balance product hardware design, functionality and technology, Sony engineers conceal the audio structure created by Sony engineers to achieve a better surround experience. With these great designs, Sony's home audio products can collaborate even more with each sound generation unit to realize their hearing potential. For example, choosing the shape and position of the speaker, the headphone fabric cover is also carefully selected before it is finally applied to the final product.
Carefully selected textile materials for acoustic and acoustic aesthetics
In the HT-A7000, the five front speakers integrated into the fuselage are space-balanced speaker units with a circular rectangular design, which effectively increases sound pressure and reduces distortion; The speakers on both sides are arranged with Sony sound duct material and the micro-hole configuration specifically used by engineers reduces sound reaching the user's ears, allowing sound to be diffuse to create a wider sound field; The loudspeaker, which is of great benefit to 360 SSM, has a fabric covering on its surface, and it also bears the ingenuity of engineers, and after many checks, the materials that help conduct the sound are finally selected.
In the HT-A9, you can also feel Sony's innovative design and powerful technical strength. In the limited body, Sony also made the full-range speaker as an ultra-thin unit that replaces the thin and light diaphragm, and the left and right edges of the body are cut at a certain angle, so that the HT-A9 can obtain a more prominent and sound acoustic guidance, and the spread enriches the sense of the surrounding field the sound ; The diaphragm of the speaker unit is made of foamed mica, which not only transmits high-quality sound, but also maintains the thinness of the diaphragm.
Because HT-A9 has advanced product shape and technology, HT-A9 only consists of four independent wireless speakers and the control box can easily realize wireless transmission. Combined with 360 SSM technology, the placement is more flexible and free, and it can be more harmoniously placed at home. Comfort and sound quality bring new experiences and breakthroughs to users. Since it needs to connect to Wi-Fi at home, if the Wi-Fi mode at home is too complicated, it may affect the use of HT-A9. To help users make better use of wirelessly connected home audio products, the following troubleshooting and optimization methods can be used:
1. Place the control box at a distance of 1 m from the router to reduce network interference caused by the radiation of the router;
2. In the wireless playback quality option of the HT-A9 setup interface, set “Set headphone wireless playback quality” to “Connect” to improve the stability of wireless audio transmission;
3. HT-A9 can also reduce interference with other wireless devices in the settings, which can be improved by the "Radio Frequency Channel" switch on the headset. If this switch is turned on, the speaker system can automatically select the best channel for transmission, but the radio interference is strong. If you choose to turn off the switch and select channels from limited frequency bands, you can prevent external radio interference and effectively improve the problem of sound loss. If the sound loss problem is still not solvable, you can also try to turn the switch again, reset and improve the signal channel transmission to prevent sound loss;
4. If the above method does not solve the network interference problem on HT-A9, you can also choose to restore factory settings or reset HT-A9.
5. You can log into Sony's official after-sales service website (https://service.sony.com.cn/index.html), or call Sony's after-sales hotline to search for professional after-sales personnel on site maintenance and other services.
