Microsoft Yahei Microsoft Yahei Case Introduction: Microsoft Yahei Microsoft Yahei Fangchenggang is located at the intersection of the southern tip of the eastern coast of China and the starting point of the southwest border, on the coast of the Beibu Gulf of Guangxi. It is one of the only two cities in China where border and coastal areas meet. The port and the city were built every year, with a total area of square kilometers. They have jurisdiction over Gangkou District, Fangcheng District, Shangsi County and Dongxing. The total population is about 10,000 people, including Han, Zhuang, Yao, Jing and other ethnic groups. It is the only settlement of the Jing people and one of the important birthplaces of Beibu Gulf marine culture. In order to further optimize the conference sound reinforcement effect of the municipal government auditorium and conference room, Microsoft Yahei unanimously decided to upgrade the original sound reinforcement system and adopt the latest audio technology and advanced management system. After strict review, all German audio products are used for the sound reinforcement systems of the auditorium and conference room of the Fangchenggang Municipal Government. Microsoft Yahei Auditorium: The main expansion adopts only a series of single-inch linear array slightly, and the linear array sub-bass adopts only a single-inch hanging bass slightly (). The series of linear array slightly units all adopt imported customized neodymium magnetic units. They have high-quality unit configuration, patented linear horns, beautiful sound quality, accurate projection, small size and light weight. The sound-raising slightly adopts an inch coaxial full-frequency slightly () with only unique branding. The internal treble of the coaxial speaker unit adopts imported voice coils. It combines the latest composite material treble diaphragm and aluminum alloy brushed horn to bring excellent sound quality performance and auditory enjoyment. The sound is natural, clear and more expressive. The floor bass uses only a dual 18-inch slightly () to provide sufficient dynamic protection. The main loudspeaker slightly, pull-out image, and ultra-low are all installed in a hidden manner. Only auxiliary slightly and stage echo slightly are used. The power amplifiers all adopt series (,,,,) with national patented designs. This series of power amplifier amplification circuits have been comprehensively optimized and adjusted on the basis of advanced and mature circuits. It uses top-level power amplifier tubes to further optimize the sound, and continues to provide surging driving force; at the same time, a power supply timing power supply socket has been added on the rear panel to support remote control of switching machines, so that it does not need to match the power sequencer in large, medium and large sound reinforcement occasions. The processing part adopts a digital mixer (), and uses a block processing chip to ensure the powerful processing function and stability of the equipment, and can realize wired control through the interface. Cooperate with audio matrix processor (), effects (), feedback suppressor (), equalizer (), audio isolator () and other equipment. Microsoft's Yahei Conference Room: Each of the conference rooms uses a soundpost (). This series of soundposts uses a European-customized neodymium magnetic unit, which has a linear sound source structure and has uniform sound; it is small box, high power, and high sensitivity; The other conference rooms use only coaxial slightly (). Cooperate with power amplifiers (,), audio processors (), mixing consoles (), feedback suppressors (), audio isolators (), power sequencers () and conference systems. The sound field of the entire meeting was full, and the sound was restored to reality and clarity. The entire Microsoft Yahei sound reinforcement system is reasonably matched, powerful, and dynamic, which ensures the smooth holding of various important municipal government meetings, and the effect has been unanimously recognized by the municipal government leaders.
