Microsoft Yahei Microsoft Yahei Case Introduction: In order to further improve the conference sound reinforcement effect of the multi-function hall and conference room of the scientific research base, the leaders of the testing institute unanimously decided to comprehensively improve the sound reinforcement system and adopt the latest audio technology and advanced management system. After strict review, the sound reinforcement systems of the multi-function hall and conference room of the national testing, testing and scientific research base all use (Snik) audio products. Microsoft's Yahei Multi-Function Hall: The main expansion adopts only a series of dual-inch linear array slightly, and the linear array sub-bass adopts only a double-inch hanging bass slightly (). The series of linear array slightly units all adopt imported customized neodymium magnetic units. It has high-quality unit configuration, patented linear horns, beautiful sound quality, accurate projection, small size and light weight. The audio and video slightly use three-frequency dual-inch full-range slightly () that are professionally customized only with unique (SNIC) sound (). The platform lip filling sound uses two single-inch full-range slightly (). The configuration of the series of slightly is upgraded and adjusted. The upgrade of the tweeter unit adopts imported voice coils to enhance the sound expression of slightly, so that this series of slightly can adapt to the needs of more sound reinforcement occasions and faithfully restore the sound. Only dual 18-inch slightly () is used for floor bass to provide sufficient dynamic protection; only coaxial full-frequency slightly is used for auxiliary slightly (). All Microsoft Yahei amplifiers adopt series and series (,,) with national patented designs and high-efficiency digital amplifiers (,). The power amplifier adopts a quasi-amplifier circuit and uses unique cooling system technology to greatly reduce the weight of this series of power amplifiers. It only has the weight of traditional power amplifiers, and at the same time improves the working efficiency, which is as high as possible; the series of power amplifier amplifier circuits are based on advanced and mature quasi-circuit. Comprehensive optimization and line adjustment have been made. Top power amplifier tubes are used to optimize the sound and continue to provide surging driving force; At the same time, a power sequencing power supply socket has been added to the rear panel to support remote control of switching on and off, so that it does not need to match the power sequencer in large, medium and large sound reinforcement situations. The processing part adopts a road mixer (), which is matched with audio matrix processor (), effects device (), electronic divider () and other equipment. Microsoft Yahei Conference Room: There are two conference rooms on the second and third floors. The slightly each conference room uses (,,,,,) respectively, and is matched with series and series digital amplifiers as drivers. It has efficient driving capabilities. The mixer uses a series of digital mixers as the audio control center. This series of mixers has a high-computing imported processing chip to ensure the machine's computing speed and processing accuracy. Full digital processing, broadcast-level sound quality, and sampling rate provide clean signals for the entire system. The entire sound reinforcement system of Microsoft Yahei is reasonably matched, powerful, and dynamic, which ensures the smooth holding of various important meetings in the testing and testing scientific research base, and the effect has been unanimously recognized by the testing and testing scientific research leaders.
