DCS Studio Enhanced Mode Sony's DigitalcineMasound Digital Cinema Audio? Dcs for short? The development of Sony Pictures Entertainment Company was developed through close communication and cooperation between Sony Pictures Entertainment Company and Sony audio experts. It created DCS by accurately measuring and collecting sound stage data of actual dubbing and recording theaters of Sony Pictures Entertainment Company and cooperating with Hollywood audio technology. The current cinemastudioex is the deepening technology of DCS. Studio enhancement mode is to use real-time DSP signal processing to produce the unique sound characteristics of the cinema, which are surrounded by multiple sets of speakers and the sense of screen distance, and reproduce the unique sound environment of Sony Pictures Entertainment Studio at home, so that people can experience the same dramatic impact as the cinema at home. It includes three sound technologies, such as studio echo cinemastudio RVERBATION, virtual multidimensional N, and screen depth matching. Each effect of these three enhancement modes can be adjusted according to the personal taste of the listener or used selectively. Among them, the studio echo is created by using the three Hollywood studios in Sony Cinema Entertainment Company and Sony's original five-channel stereo sound field digital signal processing data, which has A? Gary grant cinema? 、Ｂ? Kimnovak cinema? 、Ｃ? Music theater? The three modes make the existing listening room create a grand sound field space like a cinema, which can expand the listening range of home theaters. When using this mode, the impact of explosion and war scenes can be greatly enhanced, and the outdoor natural sound is more leisurely and realistic. As mentioned above, when the real cinema reproduces the movie soundtrack, it uses multiple speakers all hanging on the wall to output the same sound. On the contrary, most home theater systems only have five speakers? Front left/right, center and two surround speakers? , and cannot be installed on the wall. The design idea of Sony's virtual multi-degree surround sound system is to compensate for the limitation of speaker placement in home theater environment. It uses the "virtual multi-degree space" created by Sony's "virtual three-dimensional" technology to make the rear speakers? Or front left/right speakers? Reproduce the sound diffusion effect caused by multiple speakers in the theater. No matter what the original speaker structure is, when Sony's "virtual multi-dimensional mode" is adopted, the surround sound effect of ten surround speakers placed at 25-3 degrees overhead can be felt from the actual speaker, which makes people feel as dramatic as being in the scene and cinema. A big difference between a cinema and a home cinema lies in the distance between the viewer and the screen. The front and middle speakers of the cinema are not casually placed in the distance, but actually placed behind the screen, thus giving the picture a sense of depth. Compared with the two, the front speaker of home theater is much closer to the viewer. Sony's screen depth matching technology can overcome the limitation of home listening environment and compensate for the shortcomings that the front and middle speakers in home theaters are too close to the audience. It has three different depths for adjustment, so that viewers can feel that there is an ideal distance between themselves and the front speakers and get the atmosphere of the cinema. In addition to the film studio enhancement mode, Sony takes into account that when the rear speaker cannot be installed due to environmental restrictions, it uses the front speaker to generate ten virtual surround speakers and a semi-studio enhancement mode with echo effect, Semicine Masterudioex? A, B and C, each designed to represent the sound characteristics of a specific studio? This technology is especially suitable for friends who have a small family environment. Second, the digital signal processing system In the new generation of AV amplifiers, Sony adopts Dolby Digital developed by itself. ＡＣ－３? And dts new cxd-9511aq DSP digital sound field processing chip, this 24-bit DSP converter can greatly reduce the working noise compared with the common multi-purpose DSP unit, and at the same time it contains a hardware operation group, which can make the repeated operation more accurate. As early as 1998, Sony's AV cinema audio has been greatly improved, the key of which lies in the addition of CXD27 1232-bit dedicated sound stage processing DSP device. This DSP with excellent performance and high fax rate is specially designed and developed for audio processing. It is far more efficient than other chips in various digital audio processing operations. Compared with the same MIPS value, its processing performance is twice that of the traditional DSP device. Because the processing efficiency is greatly improved by using special coding work, the virtual multi-dimensional mode is realized? Ｖｉｒｔｕａｌ３ＤＭｏｄｅ? And the studio model? ＣｉｎｅｍａＳｔｕｄｉｏＭｏｄｅ? Run at the same time. In the new generation of AV amplifier, Sony adopts an improved version of CXD2712R32-bit dedicated sound stage processing DSP. Its clock speed is 2% faster than that of the old CXD2712, thus improving the potential operability. The modified code also further improves the efficiency, which is enough to cope with the new "screen depth matching" mode and studio enhancement mode? ＣｉｎｅｍａＳｔｕｄｉｏＥＸ? CXD2712R is specially developed for DSP sound field processing, which will enable the combined audio-visual receiver to carry out all sound stage processing operations of digital cinema with a single device, and create a more detailed and vivid new home theater experience. Third, the virtual matrix 6.1 channel Virtual Matrix 6.1? The processing technology has included the effect of center channel after replay in the movie soundtrack made by Dolby SurroundEx or quasi-6.1 channel coding. Sony's newly developed virtual matrix 6.1 channel? ＶｉｒｔｕａｌＭａｔｒｉｘ６．１? Mode functions include cinema echo, steering logic conversion of rear stereo channel and three-dimensional processing of all five channels. Virtual Matri X6.1 mode uses Sony Pictures' most advanced studio B? ＳｔｕｉｄｏＢ? Sound stage features, which can further expand the listening space and make the movie sound broader and more shocking. Among them, the steering logic conversion is basically the same as the conversion technology of 6.1 channel in cinema playback. The principle is to use the existing two rear channels to create a new rear center channel to replay Dolby SurroundEx or other 6.1 channel coded movie software. The cinema echo is an adjustable echo added in order to fully experience the effect of cinema replay in the family environment. In general AV amplifier, it is necessary to add one or more rear speakers to replay an extra rear channel, but Sony's Virtual Matrix 6.1 can create four pairs of virtual surround speakers and one pair of independent rear speakers only by using the existing rear speaker signals, and all of them are 25? Suspended at 35 degrees, it can produce independent sound with a high sense of direction, and the virtual rear speaker can produce sound different from the surround speaker, and the sound can be naturally converted around the listener. In addition, Virtual Matrix 6.1 has the same advantage as other Sony AV systems * * *, that is, each stereo channel is processed independently, unlike most brand AV systems that combine each channel before processing. This mode is in line with the studio enhancement mode? ＣｉｎｅｍａＳｔｕｄｉｏＥＸ? , the whole stereo surround sound and the unique sound effects of the theater can be handled more closely, coherently and naturally. For example, a bullet flies by, or an airplane flies behind, and the sound is naturally transferred from one virtual sound source to another. Its speed and motion can be fully exerted within the 36-degree omnidirectional sound range, and the effect is impeccable. Fourth, concert hall mode Concerthallmodeling? Replay function Why is the music in the concert hall so natural and friendly, and the sound effect is unique and meticulous? Sony believes that the key reason is the reflected sound of the instrument itself and the echo in the concert hall. Its latest AV amplifier has been added to the brand-new concert hall mode? ＣｏｎｃｅｒｔＨａｌｌＭｏｄｅｌ ｉｎｇ? This is to copy the sound stage characteristics of the concert hall by using computer programs and adding appropriate reflected sounds and echoes. In order to give the music a sense of direction and height, Sony adopts the most advanced three-dimensional processing. As long as the rear speakers are used, multiple pairs of high-hanging virtual speakers can be created. The actual number depends on the concert hall mode. Each of these virtual speakers has its own independent sound performance, which makes the sound regain its lost complexity. This new, wide and natural feeling is incomparable to traditional stereo playback. At the same time, using these two concert hall modes to play back two-channel CDs, even if you are at home, it is like being in two most famous concert halls in Europe. Among them, Digital Concert Hall A? ＤｉｇｉｔａｌＣｏｎｃｅｒｔＨａｌｌＡ? It is designed according to the sound stage characteristics of Amsterdam Music Hall. This concert hall reproduces classical music very well, and Sony creates the effect of this hall according to its reverberation characteristics. And the b mode of digital concert hall? ＤｉｇｉｔａｌＣｏｎｃｅｒｔＨａｌ ｌＢ? Designed after the sound stage characteristics of the Vienna Golden Concert Hall, it can transform the listening space into this magnificent concert hall. Although the concert hall mode is designed for multiple speakers to play back the sound, users should also pay attention to the digital concert hall? ＤｉｇｉｔａｌＣｏｎｃｅｒｔＨａｌｌ? The function of is to enhance the effect of stereo recording, which may not be able to faithfully replay multi-channel software. In addition to the function of the digital concert hall, Sony has also equipped the advanced AV amplifier STR-V 555ES with a device that can create a similar concert hall effect only by using a pair of speaker systems. When this function is turned on, the settings of the rear speaker will be turned off, and the audio output from the back will be switched to the front two speakers, so that all audio and virtual three-dimensional effects can be replayed only by the front speaker. At the same time, it also adjusts the sound effect according to the nature of the record and personal taste. Is it gentle? Ｗｅｔ? , standard? Ｓｔａ ｎｄａｒｄ? , straight? Ｄｒｙ? Three positioning options are available to adjust the effect to the optimal level, such as recording on a flat panel. Record only low reflection sound or even no reflection sound? Can you use tenderness? Ｗｅｔ? The setting, gentle recording with straight? Ｄｒｙ? To set the best balance possible. V. Other advanced functions 1? Novel earphone cinema mode? ＨｅａｄｐｈｏｎｅＴｈｅａｔｅｒＭｏｄｅ? It uses Sony's newly developed virtual three-dimensional technology to create a broad sound field in the listener's mind with mode echo, so as to reduce the lack of sound stage created by the 5.1-channel system when watching movies with headphones. ２? Dss corresponding to sacd advocated by Sony? ＤｅｓｉｇｎＳｔａｎｄａｒｄｆｏｒＳ ＡＣＤ? Broadband technology design, this function can extend the playback frequency of the amplifier to 1 kHz, which is suitable for the playback of the new digital standard SACD or DVD Audio in the future. ３? All six channels have the replay capability of 24 bit/96 kHz, and are equipped with a multi-channel pure audio digital system for the future? Sacd and DVD audio? And the six-channel pure analog input socket and analog signal source direct button? ＡｎａｌｏｇＤｉｒｅｃｔ? . ４? Five groups of dynamic independent identical amplification systems provide music playback comparable to pure sound combination. ５? Radio functions of 3 preset FM/AM radio channels. ６? Screen display function? ＯＳＤ? And a full-function LCD pen-touch display intelligent learning bidirectional remote controller. The attached table is the model and configuration table of Sony's new generation AV amplifier. Among them, STR-DA777ES is SONY's flagship AV amplifier at present. Except that its configuration is not as rich as V555ES, other designs are all striving for perfection, such as factory enhancement mode. ＣｉｎｅｍａＳｔｕｄｉｏＥＸ? , 24 BitDolbyDigital/DTS decoding, two sets of 32 BitDigitalcineMasound sound field processing functions, triple independent DSP LSI processing system and other functions are all the best in the whole series. At the same time, it also adopts the design of LINEARAPCORE Super Fire Bull, SF radiator for preventing harmonic vibration, eccentric insulating foot seat and large beam-frame chassis for counteracting the vibration generated by the interior and air. In addition to seven groups of high-quality high-power output terminals, other audio and video input and output terminals are available on the backplane. The external dimension of the machine is 43× 173× 465 mm and the weight reaches 24.5 kg. The most noticeable one in this series is STR-V 555ES, which is the main product of Sony's new generation AV amplifier. The basic design of this machine and the appearance size of the panel all follow STR-DA 777ES, but it has the most complete technical configuration due to the addition of Sony's latest technologies. It also adopts a high-precision ES-level dynamic amplification design like STR-DA777ES, with an output power of 145W× 5? ６Ω? . The most attractive thing about STR-V555ES is how to reproduce the positioning of the rear center in the above-mentioned family and related problems. It is the first virtual matrix newly developed by Sony. Virtual matrix? 6.1 channel system EX mode AV amplifier, its processing system
