Microsoft Yahei Microsoft Yahei Case Introduction: Microsoft Yahei Microsoft Yahei Project Background: Microsoft Yahei Dongchang Second Primary School is located in Dongchangfu District, Liaocheng City, Shandong Province. It is a school committed to comprehensive primary education. Microsoft Yahei's design and bidding for the audio reinforcement system of the multi-function hall of Dongchang Second Primary School took into account the system requirements in two scenarios: meeting and audio file playback. Based on the characteristics of conference reinforcement, a complete and concise system configuration has been carried out. On the premise of having excellent effects, the system has better controllability and improves the user's application experience. In the end, the project was successfully won. Microsoft Yahei Project Requirements: Microsoft Yahei Project involves the design of this multi-function hall. The conference room is mainly used for daily meetings and some reports. Considering that the conference room is a place where communication and learning are used more, Party A requires that the conference system must have natural and clear sounds, 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 Microsoft Yahei Series slightly: Coaxial speakers are a new generation of point sound source technology. The series provides complete sound reinforcement technology to meet the high requirements of professional audio users. The main advantage of coaxial technology is that the radiation of a single point sound source has excellent phase response characteristics. The speaker has complete wavefront coherence and axial symmetry directivity at all frequencies, producing exactly the same horizontal and vertical coverage angles, forming a true point sound source. Microsoft Yahei Series Amplifiers: A high-performance, high-reliability power amplifier; 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; Microsoft Yahei Mixer: An imported high-tech processing chip ensures machine computing speed and processing accuracy. Microsoft Yahei fully digital processing, broadcast-level sound quality, sampling rate Microsoft Yahei can save individual user scenes. Microsoft Yahei mixing console has built-in digital audio decoding sound card and supports digital audio playback (port) Microsoft Yahei series microphones: Pure discussion conference system Microsoft Yahei's main control computer has passed national mandatory safety certification Microsoft Yahei uses all-digital high-fidelity circuit development and design Microsoft Yahei's conference system host and conference unit uses eight-core dedicated signal line Microsoft Yahei Feedback and Evaluation: Microsoft Yahei system is convenient for users and simple to operate. The overall design and wiring of the Microsoft Yahei system are simple, which greatly reduces construction costs. Microsoft Yahei users can easily experience smart, convenient and practical office work, which has been unanimously recognized and praised by leaders. Microsoft YaHei
