Main Control System, the last and best important step on the procedures of interview, editing, recording and broadcast, plays a key position of radio broadcast. It assumes the responsibilities of program exchange, coordinate and transmission.

Main Functions:
1. Program Switch and Distribution in charge of sending signals of high quality programs to transmission
    station continuously
2. Receive signals from high-level radio station, satellite, wireless and wire
3. Provide audio signal sources and return program signals to studio and record rooms
4. Real-time monitor and record all the programs
5.Abnormal situation alarm and emergency response
6.Provide standard time and hourly reminder signals to all the broadcast machine room and network
7. Video monitor & control and internal talkback

Features:

· Practical and Advanced

Every broadcasting station varies in overall scale, equipment composing, organization structure and regulations. It is necessary to select the best suitable solution according to their own needs.

Digitalization and network is the development orientation of broadcast main control even broadcast system. It is recommended to remain the space for future development when selecting core equipment.

· Reliable and Safe

The key position of main control system requires reliability and safety: (1)The critical components should adopt reliable design, such as double powers, control panel and hot plug & unplug; (2) Select backup signals and redundant channels as many as possible; (3) Reduce the signal links and diversify system risks; (4) Use the passive equipment like jump wire.

· Flexible and operational

The design of main control system should switch and distribute signals on the complicated condition and make correct and quick response towards abnormal situations and accidents.

System should be intelligent and operational in monitor and auto & manual operation, which makes it easy to regular and urgent operation by working staff.

Suzhou Fortune Technology Co., Ltd develops a lot of solutions based on many years experience for users reference and designs a series of related equipment, such as DSW102/104 Intelligent Switcher, Music Set, Audio Monitor, etc, which involved in distinctive design and feedbacks, enjoying many reputations.

Solution 1:

· Digital Solution, suitable for central broadcasting Station

· Broadcast channels adopt bypass across connection to ensure on effect on broadcast when matrix happens abnormal accidents. The main and backup signals from studio and matrix will be broadcasted after DSW104 Intelligent Switcher. DSW104 will trigger alarm and make emergency response to play music automatically when audio-loss or AES3 data error.

· The matrix is in charge of the signal distribution of the whole station, sending return signals to studio and recording room to satisfy relay and recording demands.

· Multi-redundancy arrangement and easy to extent system resource.

· 24-hour monitor all the signal sources, broadcast signals and receiving signals with the alarm and record functions

· The uniform network management to realize linkage of matrix, switcher and audio monitor as well as providing intelligent control software to run program table and shortcut operation.

Solution 2:

· Suitable for analog and digital main control system

· Comprise equipment suitable for small and medium-sized station

· Broadcast channels adopt bypass across connection which can receive signals from studio or matrix and emergent broadcast to ensure flexibility and safety.

· 16*16 Matrix is in charge of the signal distribution of the whole station, sending return signals to studio and recording room to satisfy relay and recording demands.

· Return the receiving and main output signals to matrix. Monitor all the signals by matrix switch

· Get monitor signals by audio distributor and matrix. 24-hour monitor all the signal sources, broadcast signals and receiving signals with the alarm and record functions

· The uniform network management to realize linkage of matrix, switcher and audio monitor as well as providing intelligent control software to run program table and shortcut operation.

Solution 3:

· Adopt auto broadcast system (ABS) control digital mixer in order to switch signals

· Suitable for small radio station or one channel control.

· Time switch according to the program schedule with manual modification.

· 24-hourly reminder

· Fade in & out when switching

· Monitor output level with the audio-loss alarm and emergency music playing functions.

· Auto control external equipment

· Edit and modify program schedule on PC and download to ABS

Network Management Software:

Network Management Software is programmed based on users’ needs, which can connected with matrix, audio monitor and so on by LAN, RS232 or RS422 connector. The software can be run under Windows98/2000/XP or higher version with Chinese interface which is easy to operate. It can automation search qualified equipment without manual configuration and can be operated with control panel. After installing touch screen, the function will strengthen.

Functions:

· Visual Display the status and all the parameters of the main control system

· System linkage For example, when audio monitor finds audio-loss, intelligent switcher or matrix will finish emergent switch accordingly.

· By setting program schedule to switch each channel automatically on the basis of week cycle

· Strategic emergency response, operator only needs to finish one step, it will realize one or more emergency responses.

· User management realize system configuration, authority management and password setting

· Log record provides history record every month

· Search the status of main control system and operate within the authority on another PC by network
