Microsoft Yahei Case Introduction: Microsoft Yahei Project Background: Shenzhen Foreign Languages School was founded in, and is a key school directly under the Municipal Education Bureau, a first-level school in Guangdong Province, a national demonstration school in Guangdong Province, and a civilized unit in Guangdong Province. The Microsoft Yahei case involves the Gymnasium of Shenzhen Foreign Languages School High School. After on-site investigation by our professional and technical personnel and in-depth communication with users, it was found that the following problems existed at the scene: Microsoft Yahei, Microsoft Yahei, the original system just simply hung a circle of full-frequency speaker. The sound pressure level was not enough to highlight the main sound reinforcement, which could not meet the performance use; Microsoft Yahei, Microsoft Yahei, the building sound environment of the stadium was not up to standard, and the reverberation was large; Microsoft Yahei Microsoft Yahei, the original computer room has limited space and does not have the conditions to add more cabinets; Microsoft Yahei Microsoft Yahei, the traditional simulation solution used by the original system, has large long-distance signal transmission loss and serious sound distortion; Microsoft Yahei Microsoft Yahei, users hope that the original system will be improved to maximize the use of functions. Microsoft Yahei Project Requirements: Microsoft Yahei Project involves the design of the school's gymnasium. The gymnasium is mainly used for sports competitions, physical exercise, holding parties, etc. Considering that the gymnasium is a relatively large and empty activity venue, Party A requires that the overall system must have natural and clear sound, stable system operation, complete functions and efficient use. The design of the audio system in this scheme fully meets the multi-functional requirements, focusing on the fundamental advancement, reliability, practicality, economy and system scalability of the system. Microsoft Yahei Solution The speaker selected in the Microsoft Yahei design plan is a network transmission active-line array speaker, highlighting the main sound reinforcement. The main amplifying linear speaker's high-bass unit adopts imported neodymium magnetic units and adopts customized imported units from Europe. It has high sound pressure and large dynamics, and is suitable for sound reinforcement for small and medium-sized performances inside and outside. In addition, the corresponding hanging bass and floor-to-floor ultra-low speaker can fully meet the needs of live performances; Microsoft Yahei has corrected the original speaker positioning to ensure audio-visual consistency to the greatest extent possible. Microsoft Yahei's speakers are all active speakers, using third-generation high-power digital power amplification modules to minimize the space occupation in the computer room; Microsoft Yahei's solution adopts an active system, and all signals are transmitted through network cables to ensure high-quality audio signals are transmitted over long distances, and cascading audio transmission of multiple speakers can be realized through the network port. It has the advantages of fast and convenient connection; minimizing mutual interference between audio signals; Microsoft Yahei's original system is used as a sound-making speaker in the audience to maximize the utilization of resources. Microsoft's Yahei mixer adopts high-end brand digital mixer, with input channels, output, grouping, and main output. Can be controlled via a wireless network and can be controlled by applications in. Microsoft's Yahei Digital Audio Matrix Processor adopts the latest digital audio matrix processor developed by our company. It can be controlled through, smartphone, and wireless. It has remote control of power amplifier turning on and off, and digital signal input and output. Microsoft Yahei Microsoft Yahei Feedback and Evaluation: Microsoft Yahei has been carefully trained by Snick's professional engineers, and the final effect has reached the first-class standard of stadium sound reinforcement. The effect was unanimously praised by all parties.
