Microsoft Yahei Case Introduction: Microsoft Yahei Microsoft Yahei Project Background: Microsoft Yahei Caitang School implements a nine-year compulsory education system. Students are recruited. The campus covers an area of square meters, the school building area is square meters, and the sports area on the campus is reasonably distributed. The teaching areas are lined with trees and beautiful environment. The newly built laboratory is spacious, bright and fully equipped. Microsoft Yahei has sufficient design experience and practical cases for the audio design and bidding of such outdoor playground projects. Therefore, through professional design and active cooperation with customers in bidding work, it was finally successfully won the project. Microsoft Yahei Project Requirements: This Microsoft Yahei project is the school's outdoor playground. In order to ensure the sound reinforcement system for meetings and event performances throughout the playground, and improve the quality of the school's running, the school mainly adopts the German audio series linear slightly and a series of professional stage echo slightly and other major sound reinforcement equipment to meet daily sound reinforcement use. Microsoft Yahei Solutions: Microsoft Yahei Series Linear slightly: The series linear array slightly is a high-precision linear array speaker system that has large dynamic capacity and can provide clean, continuous and accurate high-quality sound. Microsoft's Yahei series of back-to-back slightly: The series of slightly is a professional back-to-back slightly specially developed by Audio for stage performances. The frequency division and frequency response are adjusted according to the stage performance design, making it difficult for stage performances to generate feedback screams. Microsoft's Yahei series power amplifiers: have extremely high efficiency, high power conversion efficiency, and high efficiency and energy conservation unmatched by traditional analog power amplifiers. This has changed the impression that audio power amplifiers are cumbersome, power-consuming, and bulky in people's minds. Microsoft Yahei Series Power Sequencer: It can turn off the power output step by step to protect system equipment from damage. Microsoft Yahei series digital processors: Built-in feedback suppression device, optional echo cancellation device, environmental noise suppression device. Microsoft Yahei Series wireless handheld microphones: Adopt the latest infrared automatic frequency matching technology and fixed microphone grouping function, making it easier to set and operate, and easier to use. Microsoft Yahei Microsoft Yahei Feedback and Evaluation: Microsoft Yahei linear array slightly patented linear horn, beautiful sound quality and accurate projection; Microsoft Yahei professional echo slightly stage performance design adjusts frequency division and frequency response, making it difficult for stage performances to produce feedback screams; Microsoft Yahei audio product design is reasonable and easy to install; Microsoft Yahei broadcasting system meets the sound reinforcement systems during performances and meetings, improving the school's teaching quality; The entire Microsoft Yahei system is smooth and stable to use, and has good sound quality. I am very satisfied.
