Microsoft Yahei Case Introduction: Microsoft Yahei Project Background: Microsoft Yahei Gymnasium is located in Jieshou City, Anhui Province. After its completion, the gymnasium can hold basketball, volleyball, badminton, table tennis, martial arts, wrestling, taekwondo, fitness dance and other sports activities, which will play a positive role in further developing the urban national fitness cause, consolidating the foundation of competitive sports, and displaying the image of Jieshou. Microsoft Yahei's design of the audio reinforcement system for Jieshou Gymnasium in Anhui Province is mainly to meet the requirements for broadcasting various music, radio and competition language reinforcement. It also undertakes some cultural and artistic activities. In addition to ensuring high language clarity, soft sound quality, and uniform sound pressure coverage, it also requires that the equipment power be large and leave margin. Therefore, we focus on meeting the stability and reliability of use in terms of scheme design and equipment selection. Microsoft Yahei Microsoft Yahei Project Requirements: Microsoft Yahei 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 Microsoft Yahei Solutions Microsoft Yahei Series slightly: The series of linear array slightly is a high-precision linear array speaker system. It has a 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. Microsoft's Yahei 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. The large-scale annular heat dissipation design greatly enhances the heat dissipation efficiency, ensures that the driving unit's operating temperature is low, greatly improves the power compression performance and reduces nipe wave distortion. Microsoft Yahei Microsoft Yahei Series Power Amplifiers: The 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 continue to provide surging driving force; At the same time, a power supply timing power supply socket has been added to the rear panel to support remote control, so that it does not need to match the power sequencer in small and medium-sized sound reinforcement situations. Microsoft Yahei Microsoft Yahei Audio Processor: The series of digital audio processors are audio processing equipment specially developed by audio to match slightly. Technology uses processing technology, high-precision floating point computing technology, network transmission protocols, and other technologies. Microsoft Yahei Peripherals: Audio isolators and power sequencers are used around the periphery to make the overall system more complete. Microsoft Yahei Microsoft Yahei Feedback and Evaluation: Microsoft Yahei's overall system is easy and simple to operate. Microsoft Yahei users can easily experience smart, convenient and high-quality venues. Microsoft Yahei customers unanimously recognized and praised it.
