Nanjing Youth Olympic Games Jinniu Lake Venue


Gymnasium, indoor sports competition, physical exercise or concert building. According to the nature of the use of the gymnasium can be divided into two categories: the competition hall and the practice hall. Sometimes, the gymnasium is also used as an performing arts center for various performing activities.

In order to avoid the situation that the sound reinforcement is not enough when holding the sports meeting, the fresh gymnasium intends to transform the sound reinforcement system of the gymnasium, which is required to meet the sound reinforcement standard of the national stadium. Rattop has provided a professional sound reinforcement system for the fresh gymnasium. The sound source equipment uses two kinds of microphones for large places, wireless conference microphones and ultra-long-distance U-section wireless microphones, with an effective distance of up to 300 meters. The audio equipment uses an analog mixer and a digital audio processor to provide sound reinforcement while maintaining sound quality. The speakers are composed of 16 double 10-inch two-frequency split linear array speakers and 4 linear array ultra-bottom speakers (single 18-inch unit), which are specially set for occasions requiring high-quality bass effect, with high reduction, authenticity and nature, high sensitivity, strong penetration, high sound pressure level, clear voice and uniform sound coverage between regions. The power amplifier is equipped with 12 dual-channel fixed-resistance professional power amplifiers, which have short-circuit protection, over-current protection, impact protection, offset protection, over-temperature protection and other protection measures, and can work stably for a long time under any impedance.
