Medium-sized meetings, academic reports, and many other activities. Therefore, the sound reinforcement system should ensure high speech intelligibility, uniform sound field distribution, good listening conditions, good sense of direction and program fidelity, appropriate sound pressure level and high transmission gain. At the same time, there must be fullness, brightness and direction when the music is amplified, as well as the shocking power of playing film and television effects.

The sound reinforcement equipment system is an important part of it. After strict selection, it was finally decided to choose the Lingjie TRS solution.
