This solution is used for the audio and video multimedia system of the concert hall in the Central Conservatory of Music. The concert hall is about 20 meters long, 15 meters wide and covers an area of ??about 300 square meters. The system functions include piano pickup and amplification. Sound, performance amplification, music playback (DVD, MD) and other functions. As a multi-functional hall with top-level sound effects, the concert hall is designed according to the standard and requires authentic music performance. As a top music conservatory in the country, the sound reinforcement system of its internal multi-functional hall is required to truly achieve high-fidelity requirements.
The Concert Hall of Gulangyu Piano School of the Central Conservatory of Music requires the sound reinforcement system to have good artistic expression, and specifically proposes that the pickup and sound reinforcement effects of the piano must be real and natural. This seemingly simple requirement contains The pursuit of the highest level of sound reinforcement system. According to the actual needs of users, special attention is paid to the needs of piano performance pickup and sound amplification. The piano is an instrument that adopts the 12-level equal temperament system. Its lowest frequency A2 is 27.5Hz, its highest frequency is C5, and its frequency is 4186Hz. Its high-frequency overtones can reach more than 10-16KHz. It is the instrument with the widest range. It has a wide sound range of 7 octaves, extremely rich expressive power, beautiful timbre, and has the reputation of "King of Musical Instruments". Our sound reinforcement system must do a more direct job of picking up and amplifying the sound of this "king of musical instruments".
Comprehensively considering Tianchuang products and similar products on the market, combined with this design location, we have adopted the latest sound reinforcement systems in the entire sound reinforcement system, from pickup to mixer to audio processing and speakers. High-end imported equipment, such as AKG special piano microphone, MACKIE ONYX 1640 recording-grade analog mixer, XTA DP448 digital audio processor, and American RENKUS-HEINZ PN series compact multi-functional active speakers. The crisp treble, rich midrange and rich bass of the piano, RENKUS-HEINZ PN series active speakers can express each of them well. The composite cone horn with patented technology is the horn that is close to the real sound in the world. It can emit crisp and penetrating treble, and with the high-quality paper plate mid-low frequency driver, it can achieve three-band balance of high, middle and low frequencies. The low frequency is powerful, the mid-frequency is rich, and the sound is full of rhyme. The speaker also comes with a power amplifier, audio processing and protection circuit to achieve the most effective protection for the speaker. Such a set of sound reinforcement design pays attention to every aspect and considers the coordination between equipment. After reasonable debugging, the sound reinforcement effect is very high and ideal.
Art is a process of pursuing perfection, and a small distortion of the sound reinforcement system is a serious problem in the ears of the artist. Because of this, during the entire debugging process of this system, everything from welding to From the layout and positioning of cables and speakers to the adjustments on the processor, after each adjustment, we asked the school leaders to listen to it, summarize the problems, and then make adjustments. We made many different attempts. The school is very satisfied with our company's serious attitude and results.
The entire system achieves the "combination of art and technology" and achieves high-fidelity effects with truly professional sound reinforcement.
