Henan campus radio network engineering and installation company

Building needs Henan campus radio network engineering and installation company elementary school campus Intelligent Broadcast Analysis: Automatic Music on the class bell, radio body do, eye care do AutoPlay, broadcast notification, broadcast to find someone, school district campus radio program broadcast in public areas. Construction advice: use economic, stable automatic constant pressure broadcast, only need to play for in terms of a primary school program, broadcast on the choice of the constant pressure to meet the requirements. In addition, the general elementary school campus area will not be great, broadcast wire cloth is also relatively simple. For ringtones, the increase in the front end of a digital automatic Wang thunder 130.0752.5005 69.139.139 www.69139139.com qq: 317061201 Zhengzhou City, the sun technology market in Milan, Building 5, Unit 2, playing 208 meter (can store about 30 minutes of music ) to achieve ringtones, eye do, broadcasting do automatic timing play, automatic control amplifier switching machine. The system features and sound quality to meet the requirements of campus public broadcasting. Second, the building needs high school campus Intelligent Broadcast Analysis: High school grades are generally three to six, not only requires a regular campus radio music bells and function, also called for foreign language teaching and examination hearing, and different grades can be achieved Play different programs, the function must also be point-addressable control, easy to use individual class training exam. Due for training and foreign language listening test, broadcast quality requirements are relatively high, especially in the high frequency part of human speech must be clear macro thick, no background noise. Better conditions within the school classrooms have been installed projectors, multimedia network terminals and notebooks lectures, which requires classroom speakers should have live sound functions, and enables local listening selection, volume control and other functions. Construction opinion: In view of the above requirements, we recommend the use of digital addressable smart FM broadcast. First FM broadcasting in the program capacity can meet the multiple programs at the same time transmission requirements, in terms of sound quality, FM radio distortion is small, and can be stereo transmission, campus FM radio after only FM Modulation - demodulation two areas, if High-quality digital audio, sound quality is absolutely guaranteed. In addition, the digital audio broadcast in automatic and intelligent control, but also conducive to the broadcasting software automatically broadcast control, hard disk mass storage can be achieved first of thousands of audio files, digital audio file format of computer editing and processing is also very convenient . On transmission, FM radio and cable television cable transmission can be no separate cloth and then broadcast lines. It can greatly reduce the amount of construction, lower construction cost, FM radio bus type wiring structure, is also very convenient system expansion. Broadcast and control, intelligent broadcasting software automatically broadcast and addressing the king in the same interface to control wind and thunder 130.0752.5005 69.139.139 www.69139139.com qq smart: 317061201 Zhengzhou City, the sun technology market in Milan, Building 5, Unit 2, 208. Hard disk automatically broadcast audio files, some software has multiple programs simultaneously broadcast function, and automatic control audio matrix, radio class peripherals. Play lists can be established in accordance with the work of multi-mode, automatic play. Most manufacturers addressable control signals are encoded using the SCA, FSK, MSK digital modulation methods, radio, television, the control signal synchronous transmission in a coaxial cable, the speaker of the terminal point to point addressable. Speaker built-in decoder circuitry to accept the master software instruction execution switch, volume control, frequency selection, signal switching and other activities. FM speakers are powered speakers, in addition to meet the smart radio outside, it can increase the scene line input, microphone input, for classroom PA, to achieve a multi-purpose machine. Third, the building needs analysis Campus Intelligent Broadcast: campus area is large, generally several thousand acres, some university campuses and by a number of campuses. University campus are divided in different functional area. On the campus radio function, the general requirements for running the program school radio station, no music bell, broadcasting and other requirements to make, but more multi-functional area, a large area, it requires different partitions simultaneously broadcast different programs, and Students are required to be used in different ways in different regions to listen to campus radio program. Construction opinion: The Construction of College campus radio should use a variety of means of transmission, multi-mode synchronous broadcast. Wired broadcasting campus public areas, dormitories and classrooms using wireless FM radio coverage, while taking advantage of the campus webcast or on demand at any time. Outdoor speakers, Yinzhu covered living area, dormitory, canteen, lawns and other public places. If 100V constant voltage constant pressure broadcast transmission, because of distance, power attenuation, wiring construction difficulty is relatively large, and costly. Currently the university campus has a CATV cable television system networks, and some schools use HFC opto-electric hybrid network for transmission. This suggested "radio and television" UNIFIED transmission, wired FM broadcast signal and cable signal "cable transmission", after reaching a different functional area, and then the audio signal and the control signal is demodulated, local small scale using constant pressure transmission. In a building built king thunder 130.0752.5005 69.139.139 www.69139139.com qq: 317061201 Zhengzhou City in the technology market in Milan sun, Building 5, Unit 2, 208 buildings or a partition to install an FM receiver control device, a fixed pressure amplifier, speakers at constant pressure direct drive, so that eliminates the need for long-distance lines, to reduce the difficulty of construction and wiring costs, and can achieve multiple broadcast and addressing. For areas not covered by public broadcasting or public broadcasting where ease of installation, you can use a wireless FM radio way to cover most of the universities have built a Western radio stations, it may also have foreign language campus radio station FM transmitter transmission signal. So students can take advantage of FM headset, listening to radio or individual flow listen campus broadcasts. Each work and learn in a highly developed network of college campuses, computers and networks all over the campus, who can not regularly listen to public radio and FM radio in terms of students and teachers can use audio-on-demand network the way, the daily broadcast audio content uploaded to the server, broadcast after the end of easy-demand listening anywhere, it may also have an audio broadcast network mode, network listen online. University campus radio station, broadcast control room should be the center of modern recording editing and broadcasting equipment, should set up a dedicated area of ??the studio and broadcasting, access to a telephone hotline live recording series broadcast in all aspects of the use of professional wind and thunder king 130.0752.5005 number 69.139 .139 www.69139139.com qq: 317061201 Zhengzhou City, the sun technology market in Milan, Building 5, Unit 2, 208
