Microsoft Yahei Case Introduction: Microsoft Yahei Report Hall is a comprehensive report hall and a basic place for holding various types of reports, speeches and meetings. Its sound system functions require meetings, academic reports, video playback, etc. It is designed based on the requirements of use. Microsoft's Yahei audio equipment is an important part of the lecture hall. Through analyzing the layout environment of the lecture hall, the audio equipment is reasonably arranged and connected, and the following audio equipment is installed so that the audience can feel the real existence of the sound source and meet the sound reinforcement requirements for high-fidelity playback. The slightly selected in the Microsoft Yahei design plan is a series of speaker slightly The speaker is a high-precision linear array speaker system. It has a large dynamic capacity and can provide clean, continuous and accurate high-quality sound. Microsoft Yahei Power Amplifier adopts a series of power amplifiers and a unique LCD working display panel design to monitor and display working temperature, working time, and working voltage, providing reliable data for sound engineers to judge the working status of the equipment. Microsoft Yahei digital audio processor uses our processor, built-in feedback suppression device, optional echo cancellation device, environmental noise suppression device. The Microsoft Yahei rehearsal room and conference room are mainly used for speech reinforcement. Appropriate sound pressure level, high sound transmission gain and language clarity are their main technical requirements, especially high sound transmission gain. According to the needs of the project, Microsoft Yahei wants to achieve good sound reinforcement effects and appropriate loudness in the auditorium. Good sound naturalness, that is, the sound image is consistent, and the sound signal is truly reproduced, so that participants can feel the real existence of the sound source and meet the sound reinforcement requirements of high-fidelity playback. Microsoft's Yahei slightly uses a series of slightly that is positioned for meetings and multi-functional sound reinforcement. Microsoft Yahei Microsoft Yahei Power Amplifier adopts the unique LCD working display panel design of the series of amplifiers to monitor and display working temperature, working time, and working voltage, providing reliable data for sound engineers to judge the working status of the equipment. Microsoft Yahei Peripherals: It adopts pre-processor, effects, equalizer, and power sequencer to meet various needs. Feedback and evaluation from Microsoft Yahei: Microsoft Yahei audio system has good overall diffusion, uniform sound field distribution, appropriate loudness, and good naturalness; Microsoft Yahei can provide clear and natural language reinforcement to meet the functional needs of daily meeting reinforcement, report demonstrations, and meeting voting.
