The latest NEXO P+ speaker amplifies the lecture hall of the Party School of the Qingyang County Party Committee of the Communist Party of China in Anhui Province.
Recently, the lecture hall of the Party School of the Qingyang County CPC Committee of the Communist Party of Anhui Province has been upgraded and renovated. This small lecture hall can hold 200 people and is mainly used for important occasions such as daily reports and meetings. Therefore, the sound reinforcement system should have high language clarity, good sense of direction, uniform sound field distribution and good listening conditions. And meet the acoustic characteristics of the national hall sound reinforcement system.
Hefei Yunzhi Science and Technology Company attaches great importance to this project. In order to meet the requirements of the demand side, aiming at the building acoustics of the site, the site sound pressure is simulated by using NEXO special simulation sound pressure test software NS-1.
Finally, the latest NEXO P12 was selected for the lecture hall as the main sound reinforcement, and the wall was installed on the left and right sides of the podium. P12 is a high-tech, multi-functional sound source speaker. It has two modes of full frequency or active frequency division, with coaxial 12-inch low-frequency diaphragm and 3-inch high-frequency diaphragm. The use of 15mm special bending plywood shell, the inner material of poplar, the outer material of birch design. The plywood shell made from the combination of the two is very strong and lightweight, with only 20KG. The peak sound pressure can reach 138dB.
And has a high language clarity and a good sense of direction, with the same series of ultra-low frequency speakers L15 placed on the ground below the main sound reinforcement. Single 15-inch, 4 Ω long-stroke neodymium magnetic thruster, the peak sound pressure can reach 139dB. Consistent with the material of P12, it can provide ultra-low frequency supplement for P12 and improve the fullness of the language. Both models are compact speakers to avoid causing line of sight obstruction to the attendees.
In order to maintain the uniform coverage of the sound field in the hall, ID24, which is the smallest of NEXO, is selected as the supplementary sound box, which is hung on both sides of the middle and rear field respectively. The return speakers of the main podium are also placed in front of the podium using ID24. The ID24 features a compact multi-function speaker with dual 4-inch drives and peak sound pressure 126dB. The speakers are powered by NEXO NXAMP Mk2 amplifiers.
Main loudspeaker: 2 P12 on the wall.
Ultra-low frequency speakers: seat 2 L15.
Peripheral supplementary sound: 2 ID24 hanging on the wall.
Podium return: seat 2 ID24.
Power amplifier: 1 NXAMP4X1MK2,1 NXAMP4X2MK2
The upgraded lecture hall meets the national hall sound reinforcement standard, restores the best sound quality effect, and the system is easy to operate. It solves the problems of uneven sound pressure level and poor language clarity in the sound reinforcement system of the traditional lecture hall, meets the needs of holding all kinds of meetings and daily reports in the lecture hall, and improves the hearing experience of users.
