The 2021 CCTV Mid-Autumn Festival Gala in Xichang will be divided into three main stages: the ring stage, the main stage and the city wall stage. The ring stage is about 36.8m in diameter, with a 2.4m wide ring on the outside and a 15m diameter movable round stage in the middle; the main stage is 64.5m long and 24.5m wide, with upper and lower stages, and the lower stage has a movable platform; the city wall The stage is divided into main city wall, auxiliary city wall, Yi small house and aisle area.
The sound reinforcement system is jointly managed by KV2, Peavey and MotiVity. KV2 provides the main sound reinforcement system, Peavey provides the processor and fill-in speakers, and MotiVity provides the power amplifier. In order to match the stage design and shooting, all the fill-in sound speakers were small-sized point source speakers, and with the assistance of lighting and water mist landscaping, the shooting went smoothly.
The main stage is performed by the KV2 VHD2.0 system as the main sound reinforcement task. A single group is configured with 1 dual 12-inch speaker VHD 2.0 and 4 single 18-inch VHD 4.18 to form a fixed external four-way sound reinforcement system, with 1 speaker on the left and right. group, able to cope with the sound reinforcement needs of the entire main stage with ease.
The main stage fill sound is handled by Peavey SPI II series point source speakers, with every two speakers combined side by side. According to different stage shapes and sound field requirements, SPI 6II 6-inch speakers and SPI 8II 8-inch speakers are used alternately. A total of 8 SPI 6II and 4 SPI 8II are used for the main stage fill.
The main sound reinforcement system of the round stage is provided by the KV2 ES1.0 system. A single group consists of 1 ES1.0 single 12-inch full-range speaker, 1 ES2.5 dual 15-inch subwoofer, and 1 ES1.8 single 18-inch subwoofer. Combined into an external four-way sound reinforcement system, each set of speakers only needs one EPAK2500R amplifier to drive, and is hidden by the stage landscaping to easily meet the sound reinforcement and stage design needs of the round stage and ring channel.
Because the large screen on the periphery of the round stage is movable, moving it to different positions according to different programs will block the direct sound of the main PA system to a certain extent. According to the demand, we arranged 10 Peavey SSE™ 26 PLUS speakers on the edge of the ring. The shape and side cutting angle of the speakers are very suitable for this occasion. They can be placed on the ground to perfectly point to the stage. Then the system is delayed and calibrated to make the entire The ring stage and the round stage achieve zero dead-angle coverage of sound reinforcement.
Other scenes such as main and auxiliary city walls, aisles, water stages, Yi houses, etc. require some for audience sound amplification and some for actor monitoring. We arrange a large number of Peavey SPI series point source small speakers at corresponding locations according to the needs to meet the needs of the area. Voice needs.
The front-end signal is converted into a network digital audio signal through the Dante transmission box, and then decoded and converted into an analog audio signal at the power amplifier cabinet. The speaker data is processed and routed through the Peavey VSX48E small media matrix, and the signal is amplified by each power amplifier.
In this system, the Peavey small speakers are driven and amplified by the MotiVity D4.2 power amplifier, while the KV2 sound reinforcement system uses its matching power amplifier.
