Microsoft Yahei case introduction: Microsoft Yahei's design of the audio reinforcement system for the Gymnasium of No. 2 Middle School in Wangcheng District, Changsha City, Hunan Province is mainly to meet the use requirements of broadcasting various music, broadcasting and competition language reinforcement. It also undertakes some cultural and artistic activities. In terms of use functions, in addition to ensuring high language clarity, soft sound quality, and uniform sound pressure coverage, it also requires that the equipment power must be large and has margin. Therefore, we mainly focus on meeting the stability and reliability of use in scheme design and equipment selection. Microsoft Yahei Project Requirements: The project involves the design of the city's stadium. The gymnasium is mainly used for sports competitions and cultural performances. Considering that the gymnasium is a relatively crowded and empty place, Party A requires that the conference system should have clear, soft sound, excellent sound quality, and sufficient loudness in the auditorium. The sound should cover the entire auditorium and performance venue to make the sound field uniform and the system has sufficient stability. Microsoft Yahei Solution Series slightly: The series of linear array slightly is a high-precision linear array speaker system. It has large dynamic capacity and can provide clean, continuous, and accurate high-quality sound; using phase correction and patented linear horn technology, it can faithfully restore spectrum signals within the specified range. Series slightly: slightly unit adopts patented dual voice coil differential drive technology and high peak-to-peak offset branch, which can show true and perfect ultra-low frequency sound. Series power amplifier: It adopts top-level power amplifier tubes to further optimize sound and continue to provide surging driving force. Microsoft Yahei Microsoft Yahei Peripherals: Effector, feedback suppressor, audio isolator, equalizer, power sequencer, make the overall system more complete. Microsoft Yahei Microphones adopt a series of wireless microphones and adopt digital vocode locking technology to effectively block noise interference in the use environment. The conference system adopts series, with high fidelity, high signal-to-noise ratio, and no sound delay. Microsoft Yahei feedback and evaluation: The overall system is easy and simple to operate. Users can easily experience smart, convenient and high-quality venues. Customers unanimously recognized and praised it.
