Center equipment of Luohe International Convention and Exhibition Center

The LAX series sound reinforcement system in the theater is hung above the stage, and the sound bridge is responsible for the left, middle and right sound reinforcement. LAX full-range speakers are used for left and right pull-down image enhancement, LAX full-range speakers are used for lip enhancement, and the combination of LAX subwoofer and subwoofer extends the lower frequency of low-frequency operation, further improving the endurance. The powerful subwoofer is overwhelming! LAX and TH 15 full-range speakers are used for stage listening; It is also equipped with CUE26C dual-frequency movie surround speakers. When it is used to play movies, it can play 8-channel surround sound after being decoded by dolby digital decoder, which makes people feel immersive when playing movies. The performance sound system and the movie playback sound system operate independently and do not interfere with each other, and their respective effects can reach the world's top performance effect, which is composed of power amplifiers matching the speaker power. The whole speaker system has achieved the maximization of performance and utility from the basic design, so that the speaker has the performance of a world-class speaker in electroacoustic conversion characteristics and timbre restoration.

The meeting room adopts LX series speakers among LAX speakers. It not only has the general mechanical protection function, but also has a small and exquisite box, which is suitable for different environmental layouts. Different box colors can adapt to different places, not too eye-catching, and maintain harmony with the overall style of the environment. It also has certain waterproof, moisture-proof and acoustic short-circuit prevention functions. The sound reinforcement system of conference hall should replay the audio signals of language and other audio-visual materials, and the distribution of speakers, the uniformity of sound pressure coverage and the mutual signal exchange of the system should be considered in the design. The playback of various audio signals is clear and not turbid. Flexible field operability, accuracy and synchronization, sufficient power reserve and sound pressure level should meet or even exceed the national standards.

The multimedia classroom adopts LX series speakers among LAX speakers, which are driven by a flash channel power amplifier. In the design, the distribution of speakers, the uniformity of sound pressure coverage and the mutual signal exchange of the system are mainly considered. The playback of various audio signals is clear and not turbid.

The body training hall adopts LX series speakers among LAX speakers, which are driven by flash channel power amplifier. The distribution of speakers and the uniform coverage of sound pressure have high language resolution and low distortion, which ensures that the high notes are bright and hairless when playing music, and the sound is clear, round and magnetic when reproducing, and is not dry.

LAX CUE26C ceiling speakers are selected in the exhibition area, equipped with CT series constant voltage amplifiers, which are distributed in the central hall 1 ~ 3 floors respectively, and can broadcast in different areas at the same time. The system usually carries out background music broadcasting, which can be converted into emergency broadcasting in case of emergency or disaster. To this end, we will partition according to different regions, and the volume of broadcast signals in each region can be adjusted by itself, so as to realize unified broadcasting and unified broadcasting system. Part of the central LED screen is a three-color screen, which can display color images and videos. The other part is a monochrome screen, which can only display "red" and "black" images, and is mostly used for slogan logo display. The LED screen signal source is collected and sent by the built-in LED control card of the corresponding terminal computer. All the contents to be demonstrated and played must be played through the pre-installed "LED Studio" software in the terminal computer operating system. The file formats supported by LED studio software are as follows: Slides.

Presentation file (*. Ppt, note: *. Documents such as doc*.xls need to be re-edited by software); FLASH file (*. Sovereign wealth funds, note: *. Exe format cannot be played); Common video files, such as (*. RM，*。 AVI。 MPG，*。 VOB and so on. ) can be played directly, and other video files need to be converted; Common image files, such as (*. BMP*.JPEG*.GIF, etc. ); The terminal computer has a built-in video capture card, which can support TV signals (TV interface), external video signals (Lotus interface) and computer video signals that do not support VGA interface. The LED large screen system of modern network technology and digital technology has played a very active role in the promotion and display of Luohe Science, Education, Culture and Art Center. In order to meet the needs of urban construction and development and provide strong hardware support in foreign exchanges, Luohe Science, Education, Culture and Art Center has specially introduced the Bosch brand simultaneous interpretation system made in Germany. The system is an infrared language distribution system, and its working principle is to use infrared transmission and distribution language, which has strong confidentiality. Suitable for all kinds of large, medium and small conference rooms and outdoor places with high confidentiality requirements. This system can modulate and transmit four languages simultaneously. Participants only need to be equipped with an optical receiver to listen to the speech by selecting channels.
