The hotel is surrounded by green trees, singing birds and fragrant flowers, and facing the sea to the east, with blue skies and blue seas, and an elegant environment. This project is mainly about the design of sound and lighting in the wedding hall in the hotel. Based on many factors, the acoustic part of this design uses audio-related products. The Microsoft Yahei Wedding Hall is large in area and uses two main amplifying slightly, two subwoofer boxes and only auxiliary slightly. In order to prevent sound delay and howling problems, a digital feedback suppressor has been added, and a mixing console has been added to perfectly integrate the sound. From the appearance, these slightly products of Microsoft Elegant Black are all made of black paint technology, with a stable atmosphere, beauty and elegance; in terms of performance, the penetration and timbre of the treble part of the slightly are excellent, and the midrange part is rich and full. Every detail of the main and auxiliary slightly of these series is natural and free without dragging water. The sound is transparent and the sound quality is excellent. Microsoft Yahei Microsoft Yahei is worth mentioning is our heavyweight subwoofer slightly (slightly). This low-frequency slightly maintains the unique sound characteristics of the audio. They are suitable for the extended use of all low-frequency sound reinforcement systems. slightly is made of multi-layer Russian birch plywood material, and the interior is also strengthened according to different treatments so that slightly can withstand the stronger impact of the low-frequency unit; the slightly unit adopts patented dual voice coil differential drive technology and high peak-to-peak offset branch, which can display 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 the noise wave distortion. Can provide clean, deep, explosive low-frequency sound effects. The blend of Microsoft's antique decoration style with modern technological products, and the design concept of harmony between man and nature, the perfect combination of the two sparks passion. Being in it allows you to experience an audio-visual feast immersively.
