Soundking invest in a speech intelligibility and even coverage of sound pressure ensured sound system with high dynamic and reserve power for 1600-seat Shandong Linpan Gymnasium, which is the largest indoor stadium in Linyi County at present.
The main sound reinforcement system is composed of 10 groups of two-way full-range line array loudspeaker G208 and subwoofer G208S, which ensure accurate coverage projection of sound and provide consistent sound pressure coverage for all seats. The competition venue is vertically covered with four supplementary speakers H15, four V12 speakers are used for listening back to the rostrum, and the powerful amplifiers AE2200 and AE3000 are of high sound quality.
G208 adopts core components such as high-frequency wave guide horn, intermediate frequency phase plug, high and medium bass speakers, etc. The surface of the box is sprayed with wear resistant and scratch resistant high hardness black gold sand paint, the box part is made of solid and moisture proof high-quality birch plywood, and the box interior uses multiple strengthening structures to fully reduce the energy loss caused by box resonance. It makes LF sound more solid and full of impact under the condition of high power and high sound pressure. A plane wave converter is used to convert the high-frequency audio waveform from spherical wave to equal phase plane wave, which greatly reduces the high-frequency interference effect and greatly improves the sound clarity at a long distance. Double handles with safe ergonomic structure are installed on both sides of the loudspeaker for easy handling. The intelligent flying system makes installation and disassembly more convenient and fast.
G208S is a double 15 inch inverted subwoofer. Its advantage is that a cylindrical inverted hole is designed on the loudspeaker to allow the air inside and outside the box to circulate. When the speaker works, after the back radiation passing through the phase inversion tube, the sound wave of is radiated to the front, superposed with the sound wave in front of the loudspeaker, and then radiated forward uniformly, which greatly enhances the LF effect and is very suitable for professional stadiums.
AE2200 power amplifier is a multi-channel high-power professional power amplifier, which is designed with switching power supply and TD technology. The power supply voltage of the power amplifier changes with the size of the input signal, and the power amplifier voltage always follows the music signal when playing. It has the efficiency close to that of class-D structure power amplifier and the sound quality of AB power amplifier. Advanced ventilation and heat dissipation device is adopted. Professional safety protection circuit: including DC protection, input overload protection, short circuit protection, transmission overload protection, over temperature protection, switch soft start protection, clipping distortion limitation, highly guarantee the safety and reliability of power amplifier.
The professional monitor speaker V12 is designed with two crossover. The frequency response design based on the auditory characteristics of the human ear ensures the durability of hearing. Even if you feel it for a long time, it is not easy to produce a sense of irritability.
This time, Soundking successfully served in Shandong Linpan Stadium, transmitting the shining "sports spirit" with its voice, which once again proved the excellent quality and reliability of Soundking's sound reinforcement system. Soundking will also use each project as a starting point and incentive to contribute its own strength to more domestic and foreign sports projects!
