Red Education Base of the Public Security Bureau This project is a red education base of a public security bureau in Shandong. It is a place that integrates language sound reinforcement and music sound reinforcement. It can be used for the public security bureau to conduct daily conferences, various cultural performances, press releases, and major events. 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. According to different functions, it can be quickly and flexibly combined into a sound reinforcement system that meets the needs of the scene. The sound reinforcement equipment system is an important part of it. After strict selection, it was finally decided to choose the Lingjie TRS solution.

Product description
Main sound reinforcement speakers: The main sound reinforcement speakers are composed of 8 V-10 linear array speakers plus 2 subwoofers VS-15 to form a line array sound group, which are distributed on both sides of the stage and can meet the sound reinforcement of audiences in the mid and far field and the competition venue.
The V-10 full-frequency box is equipped with a 10-inch woofer and two 1-inch treble drivers. The compression cavity phase plug mounted on the front of the 10-inch cabinet is combined with an optimized waveform generator coupled between two tweeter drivers to form a 10° vertical wave surface, generating very thick low frequencies and bright treble. There are two options for the horizontal radiation angle: 80° and 120°, just choose a different horn.

2、In order to make up for the problem of the angle of vertical coverage of the linear array speakers, we designed two 10-inch passive two-way full-frequency speakers C-10 at the front of the stage to ensure that the stage area has sufficient sound pressure level.
C-10 is a cost-effective, versatile two-way loudspeaker. It has high efficiency conversion performance and can meet various professional sound reinforcement applications, such as: fixed installation, small and medium-sized sound reinforcement system, and as a supplementary system for mobile performance use. Its compact box design is especially suitable for comprehensive projects in various multi-functional halls and open spaces.
The C-10 treble guide tube is designed by computer simulation, using a CMD (measurement matching) structure, in order to achieve the best diffusion angle and perfect fusion of high and low frequency bands.
C-10 uses high-precision compression driver, with smooth, wide directivity and excellent power active protection performance. Bass driver is a new drive system with a breakthrough design newly developed by Lingjie Audio R&D team. It provides an extended low-frequency broadband and a consistent acoustic experience. It can provide perfect performance without ultra-low frequency speakers.

3、Subwoofer: The auxiliary speakers use two 18-inch passive speakers B-188, to ensure that the back field has sufficient sound pressure level to improve language clarity and sound field uniformity.
B-188 high-efficiency ultra-low frequency speaker is an ideal ultra-low frequency optional equipment for the system two-way loudspeaker. The ultra-low frequency unit is a precision high-power 18-inch woofer with a four-inch inner/outer double-layer voice coil, which can minimize the power compression phenomenon at the monitoring point and extend the life of the speaker unit.
