Microsoft Yahei Microsoft Yahei Case Introduction: Microsoft Yahei Project Background Microsoft Yahei is another multi-occasion sound reinforcement project successfully won by Audio's technical service center in Chongqing actively cooperated with customers. These include on-site investigation, demand communication, plan design and bidding cooperation, until providing technical support and on-site installation guidance after the project is won. All Microsoft Elegance and Black are provided by Chongqing Technical Service Center. Whether it is one-stop service, quick response to needs at local locations or professional technical support, it has won a lot of praise for audio. Microsoft Yahei Microsoft Yahei Project Requirements Microsoft Yahei uses audio in two locations in Chongqing Agricultural Bank this time, namely the digital conference room and the large multi-purpose hall in the building. The conference room can accommodate multiple people holding meetings at the same time, and needs to meet the sound reinforcement needs of daily meetings. Therefore, the sound pressure level of slightly and the language clarity of playback are relatively strict; and it is equipped with a spliced large screen, so the audio equipment used must be able to be used in conjunction with the large screen; The multi-function hall needs to take into account multiple functions such as meetings, reports, and performances. It is a hall that can accommodate people. Compared with the conference room, the sound pressure level requirements for the slightly are higher, and the sound must be clearly transmitted to every corner of the report hall. Microsoft Yahei Microsoft Yahei Solutions Microsoft Yahei issued a total of three professional technical drawings for customers this time. Together with the plan design list, it played an important role in guiding customers in their installation during the bidding period and after winning the bid. Microsoft Yahei series linear array slightly: With high-quality unit configuration, patented linear horn, beautiful sound quality and accurate projection. Microsoft's Yahei series floor ultra-low slightly: adopts dual voice coil differential drive technology and high peak-to-peak offset technology. Microsoft Yahei series network active slightly: It is an active slightly with network () transmission, with a third-generation high-power digital power amplification module. Microsoft Yahei series coaxial slightly: adopts point sound source coaxial technology, which has complete wavefront coherence and axisymmetric directionality, producing exactly the same horizontal and vertical coverage angles, forming a true point sound source; Microsoft Yahei series professional stage echo slightly: adopts imported unit configuration, the treble has overcurrent and overvoltage protection technology, and the bass adopts new material speaker driving technology. Every detail is naturally and freely without dragging water, and the sound quality is very clear. Microsoft's Yahei series monitoring slightly: Active monitoring slightly adopts independent driving circuit design. Each slightly drives the speaker unit through its own active power amplifier module; the tweeter has a separate level gear adjustment knob. Microsoft Yahei Series Power Amplifiers: Features a display to display: working temperature, date, time, working voltage, back board input mode selection and sensitivity selection. Microsoft Yahei Series Power Amplifiers: The rear panel has a power supply sequential power supply socket. It can realize remote one-button control of equipment switching; the unique LCD work display panel design monitors and displays working temperature, working time, and working voltage, providing reliable data for sound engineers to judge the working status of the equipment. Built-in limiter is a protective circuit that can be very effective in preventing damage to the speaker. Microsoft Yahei Digital Mixing Console: Using imported processing chips, the device can store individual user scenes, individual channel scenes, individual scene, and individual effect scenes; high-quality, input-output conversion; dual stereo effects; inch display; remote control, computer wireless control. Microsoft Yahei Digital Mixer: Supports digital network audio input and output transmission functions; inch color touch screen; can be remotely controlled and wirelessly controlled by a computer; electric push rod. Microsoft Yahei series audio matrix processors: adopt protocol transmission and have a networked control center. Microsoft Yahei series wireless microphones: Duan one-to-two wireless microphone with display screen; LCD display; infrared automatic frequency matching function; adopting true diversity receiving circuit design. Microsoft Yahei Series Conference System: Discussion tape conference host; adopts eight-core power supply and audio transmission; multiple conference modes are optional, and external computer software can be connected. Microsoft Yahei Series Microphones: Wired gooseneck capacitor single-point microphone; two power supply methods can be selected from illusion. Microsoft Yahei peripherals: digital network audio transmitter, effect device, feedback suppressor, audio isolator, signal distributor and power sequencer. Microsoft Yahei Feedback and Evaluation Microsoft Yahei's complete sound reinforcement system finally showed perfect sound reinforcement effect; Microsoft Yahei localization services responded quickly and effectively; Microsoft Yahei system runs stably and is convenient to maintain; the technical data and technical drawings provided by Microsoft Yahei solution design are complete, which greatly facilitates the early understanding and later installation of customers and Party A.
