On April 13-14, the two-day 2019 Jiang Xiaobai YOLO Youth Culture Festival in Xiaobai, opened in Music Plaza, Changlong Resort, Guangzhou. This is a holy place to show the essence of youth culture. There are music, basketball, hip-hop, graffiti and skateboarding. The audience can not only feel the sincere sincerity of Jiang Xiaobai YOLO Youth Culture Festival in an all-round way, but also see many new generation rappers with attitude, ideas and strength appear on this stage.
The field environment is complex and the requirement for audio system is high.
The large-scale performance of 2019 Jiangxiaobai YOLO Youth Culture Festival was held in the outdoor venue of Music Square of Changlong Resort in Guangzhou. The scene is divided into five stages, with nearly 50,000 square meters, and can accommodate more than 50,000 audiences. During the performance period, it happens to be stormy weather, and the rain curtain formed by rainwater attenuates the wireless signal; in addition, the open stage space and numerous crowds of people interfere with the wireless signal greatly, such as rainwater, human body, mobile phone signal and the supplement of the field signal base station. Therefore, the audio system products of the live wireless performance should be high-guaranteed, high-quality, high-restoration and high-stability. Ensure the performance is completed smoothly.
For this reason, the organizer chose Relacart P1 single channel true diversity professional wireless performance microphone system. The receiving mode of true diversity is more stable, automatic selection of frequency, elimination of receiving dead spots, avoidance of frequency interruption. True diversity receiving system uses two same channels of receiving circuit to minimize the noise and leakage caused by radio frequency interference.
Just Battle Stage
For two consecutive days, on Just Battle stage, Relacart wireless performance flight case was used, including four sets of P1 single channel true diversity professional wireless performance microphone system, four wireless handheld microphones, a R-14D diversity antenna system and a pair of R-22AU active directional antenna system to capture signals accurately, avoiding series frequency and frequency interruption caused by dead spots. Phenomena, with strong functions and strong stability, give full play to the enthusiasm of hip-hop dancers, personality publicity; and host online clear voice broadcast real-time results.
Basketball match stage
In the stage area of basketball matches, it also attracts a large crowd of spectators, with a high voice and extraordinary liveliness. On-site use of P1 single channel true diversity professional wireless performance microphone system as the host throughout the sound transmission, P1 can meet the needs of various live performance stages, the receiver itself true diversity reception and wider bandwidth, frequency non-interference, more frequency options and other characteristics, even in the case of dense spectrum space can ensure the cooperative use of multiple transmitters. It is specially designed for large-scale performances, especially for outdoor activities.
Relacart antenna distribution system is added to the configuration, including a R-14D diversity antenna system and a pair of R-22AU active directional antenna systems, mainly to meet the needs of signal adequacy for outdoor large-scale performances. R-14D diversity antenna system is a distributed antenna distribution system with ultra-wideband, strong output power and ultra-low internal modulation distortion. It is suitable for UHF high-broadband wireless systems. It is used in large outdoor performances with R-22AU active directional antenna system. A pair of antennas can be shared by cascade, and it can support up to four wireless or other wireless systems. The antenna configuration project has been improved and the system efficiency has been improved.
This 2019 JiangXiaobai YOLO Youth Culture Festival, covering a wide range, large number of people, rainy weather, complex and harsh environment, there will be a lot of interference in all aspects, there will be many signal dead spots. At this time, we need to use a directional antenna with high gain. Using an antenna amplifier is like adding a telescope, which can amplify the weak signals received by the antenna.
