Luohe campus radio monopoly Henan Jiaming Yang 1503 +71780 +75 www.69139139.com 1399 +229 +631 Milan sun, Zheng * City Market Building 5, Unit 2, 208 below several different levels of user case put forward different construction advice. , The elementary campuses smart campus radio building needs analysis: the on class automatic music bell, the campus radio body cao, eye care cao automatically play, the campus radio notify campus radio to find the public areas of the campus area radio show broadcast campus campus. Construction of views: selection of the economy, stable automatic constant pressure campus radio just need to play a set of programs for primary schools in terms of selection of the constant pressure campus radio to meet the requirements. In addition, the average elementary school campus area will not be great cloth campus radio line is also relatively simple. Add a digital AutoPlay instrument for music ringtones, the front-end (which can store about 30 minutes of music) Ringtones eye cao, campus radio the cao automatic timing play, automatic control amp switching machine. Functionality and sound quality of the system to meet the requirements of the campus public campus radio. Middle school campus intelligent building needs of the campus radio Analysis: The secondary schools are generally three to six year requires not only function with a the music bell and conventional campus campus radio also asked for Listening Teaching and examinations, and to achieve different grades can play a different program, the function must also be a point-to-point addressable control to facilitate the use of the individual class training exam. Requirements for foreign language listening training and exam requirements of campus radio sound quality is relatively high, especially in the high-frequency part of the human voice voice clear macro thick, no background noise. Better conditions in classrooms installed projectors, multimedia network terminals and notebook lectures, which requires classroom speakers should also have a live sound, and can realize the local listening options, volume control and other functions. Construction of views: In view of the above requirements of recommended digital FM addressable intelligent campus radio. First FM campus radio programs in program capacity can meet the transmission requirements, in terms of sound quality, FM campus radio distortion and stereo transmission campus FM campus radio after only FM modulation - demodulation two aspects high quality digital audio, the sound quality is fully guaranteed. In addition, the digital audio in automatically broadcast and intelligent control, but also conducive to the campus radio software automatically broadcast control hard disk mass storage of thousands of first audio file can also be achieved, the digital audio file format computer editing and processing it is also very convenient. On the transmission, the FM campus radio and cable TV, cable transmission, without a separate cloth campus radio line. Construction can greatly reduce the amount of wiring bus structure to reduce the project cost, FM campus radio is also very convenient system expansion. Aspects of in intelligent broadcast and control, the the intelligent campus radio software automatically broadcast with addressable control in the same interface. The audio files hard disk automatically broadcast, some software also has multiple programs simultaneously broadcast audio matrix and automatic control, radio paramount peripherals. Can create play list in accordance with the multi-mode automatic play. Most manufacturers have adopted addressable encoded control signal SCA, FSK, MSK digital modulation approach, campus radio, television, synchronous transmission of the control signal in a coaxial cable, peer-to-peer-to-end speakers addressing. Speakers built-in decoder circuitry to accept the instruction of the master software, the implementation of the switch machine, volume control, frequency selection, signal switching action. FM Speaker is an active speaker, addition to meet smart campus radio, you can increase the field line input, microphone input, for classroom live sound machine.
