How is the school broadcasting system composed?

Component input devices are mainly composed of digital sound sources and analog sound sources. Nowadays, digital sound sources represented by DVDs and computers are commonly used, and the application of analog sound sources such as tapes and videotapes is relatively narrow.

Broadcast control part. Including broadcast server (installing broadcast system software), network switch, sound source equipment (network microphone, network mixer, CD player, digital tuner, etc.), monitoring speaker, etc. Transmission part.

Campus broadcasting is composed of a complete set of system equipment, mainly input equipment, transmission equipment, processing equipment and output equipment.

What equipment is required for the campus digital IP network broadcasting system?

1. Program source equipment: DVD, CD, digital tuner, computer, mobile phone, campus radio player, recording card, etc.

2. It can independently control each terminal to play different content (for example, 200 terminals in the local area network play 200 programs at the same time). It can not only fully realize the role of the traditional broadcasting system (such as: Regular ringing, partition playback, fire alarm, etc.), and it also has the functions of terminal free on-demand, two-way intercom between terminals, etc.

3. IP network host: The network broadcasting system requires a high-performance IP network host to ensure the stability and reliability of the system. Network paging microphone: It can transmit the paging microphone signal in the IP network to realize the function of remote paging control.

4. It is composed of IP network host, network digital audio broadcasting software, IP digital broadcasting terminal, terminal controller x0dx0a (supporting equipment), network paging microphone, constant voltage amplifier, audio and other equipment; the other is to directly embed the integrated version of the network audio module into the playback device. P network terminal decoding speaker.

5. Multimedia communication: IP network broadcastingThe system can send alerts and notifications to various areas and equipment on campus through a variety of media forms (such as voice, text, pictures and videos). This information can be transmitted to designated terminal devices through the network, such as computers, mobile phones, TVs, broadcasting systems, etc.

6. The IP network broadcast host is the core of the network audio broadcast system. Setting up the IP network broadcast host requires the following steps: connect hardware devices: connect the IP network broadcast host to the network, audio, microphone and other devices to ensure that the devices can communicate normally.

Campus broadcasting system debugging skills

The setting steps of the campus broadcasting system are as follows: 1. Confirm that the broadcast host and amplifier equipment have been installed and can work normally.2. Turn on the power of all the required sound source devices and confirm that the audio cable is connected correctly. 3. Adjust the volume of the sound source device to the appropriate size, and adjust the volume of the amplifier to the minimum.

The public broadcasting system equipment is usually installed in the cabinet. If it is a relatively simple system cabinet, it may be smaller, such as a 0-meter cabinet. There are fewer machines and the cabinet is relatively short. Try to install the equipment up, and the automatic broadcast host should be placed on the top as a frequently used and frequently debugged equipment. It is convenient for debugging and use.

The steps are as follows: determine the location and quantity of broadcasting system equipment, and design the hardware, including speakers, sound columns and control equipment. Select the appropriate broadcast software, establish a broadcast server, and connect the audio resources and detection resources on the server to the speaker to ensure the reliability and stability of the system.

Turn on the switch of the campus broadcast. After the broadcaster works normally, find the exit button on the front of the machine. After finding the exit button, press and hold the exit button for more than 2 seconds until the machine display lights up. After the screen lights up, use the arrow keys to select the system time and press confirm.

Follow the following operation steps to turn on the switch of the campus broadcast and keep the machine on. Wait for the machine to warm up and run normally. Find the "Exit" button on the front of the machine. Press and hold the exit button for more than 2 seconds (until the display of the machine brightens).

Setting on [Computer]: Connect to the computer--. Partition timing software - open the path - select "Removable Disk" to select the folder with the song. Start time (select according to the scheduled schedule) - select the number to play (select according to the marked song number) - save the time - add the time.
