Microsoft Yahei Case Introduction: Microsoft Yahei Trial Court mainly carries out language reinforcement. Appropriate sound pressure level, high sound transmission gain, language clarity, and small sound pressure level unevenness are its main technical requirements, especially High sound transmission gain. According to the needs of the project, Microsoft Yahei wants to achieve good sound reinforcement effect 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 Yahei solution: Microsoft Yahei series sound pillars: small box, high power, high sensitivity. Microsoft Yahei Series Power Amplifiers: The series is specially equipped with a nonlinear comparator. When the signal is clipped, the power amplifier can immediately adjust the working state of the circuit until the clipping is eliminated. Microsoft Yahei series digital audio matrix processors: The audio matrix processor can realize remote cross-network segment control over Ethernet, and can remotely debug and maintain equipment in real time, solving the problem of long response time for product application debugging and after-sales maintenance. Microsoft Yahei Peripheral uses a power sequencer. The sequencer can start various devices one by one in the order of the system from the front stage to the back stage; when shutting down, it turns off the devices from the back stage to the front stage. Microsoft Yahei Microphones adopt a series of gooseneck microphones with capacitive transducer and cardioid pointing. Microsoft Yahei Feedback and Evaluation: The system is easy to operate, the overall design and wiring are simple, which greatly reduces construction costs, and has been unanimously recognized and praised by customers.
