The functional requirements of the network IP broadcasting system in lingqiu, Shanxi Province:

1) : the system is expected to adopt IP network as the transmission medium, can use all the existing network hardware resources, demand systems may authorize broadcasting multiple locus of control, a full range of centralized control management system, and the regional independent control management, there are multiple remote radio control points, have a phone radio and intelligent power management functions, strong expansibility of the system. The output of power output adopts the method of constant pressure output. Each speaker is connected to the music line by the appropriate transmission transformer according to its power size and impedance value.

2) : the greening area adopts the molding speaker; In the landscaping area, the outdoor garden style speaker is installed in the ground floor.

3) the configuration of the speaker should ensure that the sound pressure level of music can reach a certain degree of uniformity.

4) the system shall be equipped with a security loop, which will automatically cut off the connection with the host equipment when the circuit of the speaker circuit is short-circuited to ensure the safety of the amplifier and control equipment;

5) : the location of the stereo should be taken into consideration of the road, the entrance and the study place.

6) : broadcast to satisfy various requirements: in addition to the normal school, public broadcasting, the realization of the background music, and other functions, considering the new characteristics of modern radio, must consider radio and fire control linkage, obligate fire control interface, and to achieve remote or beyond the radio is broadcasting design must consider the question.

7) : the student accommodation area needs to be played on a separate background music. The system needs to provide multiple sets of background music, which can be used for local selection and audio control in the terminal area.

The HARMAN IP network broadcast system is the world's leading broadcasting system. In the 21st century, electronic technology will inevitably develop in the direction of digitalization and networking, and computer control technology will infiltrate almost all applications. HARMAN IP network broadcast system based on this concept to carry on the design and construction technology, traditional intelligent broadcast, nc broadcast incomparable technical advantage, and can be applied to more broad application environment. It using the computer Internet of digital audio signals (LAN/wan) system: perfect, stable, convenient and CD grade quality, combination of arbitrary partition, interactive on-demand, timing, fixed-point infinite, two-way radio broadcasting, audio, intelligent switch machine, the network alarm; There is a network of places, randomly add, freewill, cover all kinds of broadcasting of the past all functions. It is widely used in public places such as airports, railways, villages, highways, large parks, large shopping malls, supermarket chains, large campuses, digital safe cities and other public places.

Digital network public broadcasting system USES IP Audio ™ technology, the Audio signal in the form of standard IP packet transmission in LAN and wan, is a set of pure digital network transmission of two-way Audio amplification system. It has solved the problems of poor sound quality, complex management and lack of interactivity. The system equipment is simple to use, installation is convenient, you only need to digital audio terminal access to a computer network can be a powerful digital broadcasting system, each access point without the need for a separate wiring, realize the computer network, digital video monitoring, public broadcasting more nets.
