A school in Tianjia'an District, Huainan City

There is a small multi-function hall in the school that needs to make a set of sound reinforcement system, which is required to meet the needs of the school's internal small activities and meetings. The microphone voice is required to be clear and free of noise, singing is easy and effortless, and will not scream or make other harsh sounds during use. The activity room is 8 meters wide, 10 meters long and 3.5 meters high. According to the above requirements, the ZRSO (Natori) 10-inch professional speaker ZR-Y26 was selected. This speaker has wide frequency response, high sensitivity, large power, balanced curve, accurate phase, soft sound, and bright, clear, soft and solid listening feeling when music is replayed. One is arranged at each corner, and the sound pressure of the whole field can be close to 110DB, which meets the needs of activities and meetings. The power amplifier uses ZRSO (Natsuma) TS-350. The power amplifier is dynamic enough and has large reserve power. It can push the speaker to burst into huge energy instantly, and the full range is perfect. In addition, a front stage effector is equipped with 15-segment parameter balance adjustment, which ensures the safety of the system and avoids equipment damage caused by misoperation during the use of the system. The front effector processes and modifies the voice and music to make the sound closer to the real sound. A good sound system is to restore the real sound to the maximum extent. This system is simple and easy to use, which is highly approved by customers and users.
