Section 2: Broadcast System Design for Campus

According to the school's requirements, we have designed the broadcast system to beIP Network Broadcast SystemThis broadcast system is a pure digital transmission two-way audio amplification system. It completely resolves issues such as poor sound quality, limited transmission distance, and lack of interactivity that exist in traditional broadcast systems. The system's equipment is easy to use, requiring only the connection of terminals to the computer network to form a powerful digital broadcast system. Each access point requires no separate wiring, achieving the integration of computer networks, digital video, and public broadcasting into a single network.

Functionally: Capable of independently controlling the content played on each terminal, enabling point-to-point broadcasting. It not only fully realizes the basic functions of traditional broadcasting systems, such as scheduled bell ringing, zone-based playback, announcements, fire alarms, and other fundamental requirements, but also offers features like audio on-demand, amplification of local multimedia system inputs, local microphone speech amplification, and programming playback by general users.

Transmission: Infinite audio transmission distance, effortlessly achieving remote area broadcasting and remote broadcasting. Even from miles away, the sound remains clear and smooth, as if heard live. An advantage over traditional analog broadcasting systems.

Sound Quality: Utilizes PCM uncompressed format encoding, achieving CD-level sound quality, ideal for high-demand situations, no longer troubled by unclear audio.

Product Application Scope: Kindergartens, primary and middle schools, universities, and various public domains.

System Front-End Audio Design

The audio sources for campus broadcast systems consist of both digital and analog sources. Digital sources include IP network CD players and IP network tuners, which can be directly connected to the network. Analog sources are traditional devices such as DVD players, digital tuners, broadcasting microphones, and wireless microphones. These parameters require coordination with an audio matrix or an IP network mixing console for use. IP broadcasting double 2. Terminal amplifier and speaker design

Classroom: Design and install 10W wall-mounted digital network backup speakers; there are X classrooms in the teaching department, requiring a total of X digital network speakers. Speaker features: This speaker combines network decoding amplification and speakers into one unit, and has input ports for audio signals and 100V constant voltage input. When teaching with a desktop computer or laptop in the classroom, the sound output from the computer can be amplified through this speaker. In case of network issues, the speaker can receive traditional 100V constant voltage backup signals to ensure continuous sound, preserving the integrity of listening test content. To achieve balanced sound in the classroom, an additional speaker is designed and installed in each classroom, with the two speakers installed on opposite sides of the blackboard. Broadcast system

Corridor of Teaching Building: Install wall-mounted speakers with IP network amplifiers in the corridors of the teaching building. Generally, it is recommended to install a 10W wall-mounted speaker every 8 meters or so. The power of the amplifier is usually 1.3 or 1.5 times the total power of the speakers.

Outdoor Sports Playground Area: In accordance with the division of functional zones, a broadcasting room is set up at the grandstand area, planning for 1 fixed broadcasting zone. Designed with 10 120W outdoor waterproof sound columns, equipped with 1 pure power amplifier, 1 network decoding terminal device, and 1 set of wireless microphones. This area is under main control management and can be independently controlled for playback. Equipped with a wireless IP remote controller and an IP front-end microphone controller, the wireless IP remote controller allows for remote control of playback, pause, volume increase or decrease, and other operations. The IP front-end microphone controller features a strong cut function, which can automatically turn on the power amplifier or terminal when a signal is input (either microphone or line signal), enabling broadcasting to the designated area.

3. Comprehensive System Design for Dual-Campus Broadcast System

In terms of control, we utilize:IP Network Broadcast ServerIP broadcast system software, as well as decentralized control management software. Color screen desktop paging microphones are equipped in each grade office, with the system enabling single-grade control and management functions in the control and management aspect.

Section 4: Key Function Description of the System Products for This Project

1. The audio source plays normally without issues on the server equipment.

All IP network peripheral products (network audio matrix, network audio source, network fire alarm matrix, network scheduler, network remote control, and network front-end microphone control) within this system are used directly in the network without passing through a server. Even if the server experiences a power outage, music playback can continue normally without any disruption. Most network products on the market today require server mediation, and if the server goes down or malfunctions, the entire system becomes inoperable. This includes fire alarm systems that operate directly in the network. This method ensures quick alarm response and enhanced safety.

2. The server equipment plays the voice notification normally without disconnection

All IP intercom alarm devices (network paging intercom master console and network intercom alarm terminal) within this system are used directly on the network, without passing through a server. Even if the server is powered off, the network paging intercom master console can still control network terminal devices, notify speakers, and play local audio signals. The intercom alarm function also operates independently of the server, working directly on the network.

3. Paging host supports PCM encoded paging format

The paging host output encoding format is PCM uncompressed, supporting a 320K audio bitrate, ideal for background music enjoyment. No more worries about unclear sounds or excessively long speech delays. It completely resolves issues such as poor sound quality, ineffective effects, and the tendency to generate noise in broadcasting systems.

4. Server supports WAV music format

The server is compatible with standard English listening test files, eliminating the need for format conversion. It plays directly for listening, with each pronunciation clear and distinguishable, making it ideal for listening tests and similar venues.
