To get rid of the traditional equipment and chaotic cable installation, it use Cat.5 cables to keep the sound quality and save construction costs and maintenance costs.
Use audio trigger device to link the signal sources from different devices (such as computers, DVD players, earthquake alarms, etc.) to prevent signals loss and let teachers and students receive all message and respond the emergencies.
IP broadcasting software includes three types:
- Audio Server- Start up the IP address of the broadcast server automatically.
- Audio Configuration- Automatically detect the connection status and IP address of each device in the network domain. It can also remotely control the upgrade function replacing the traditional time-consuming updating work for different classrooms. Use audio trigger device to link the signal sources from different devices (such as computers, DVD players, earthquake alarms, etc.) to prevent signals loss and let teachers and students receive all message and respond the emergencies.
- Net Audio Program- The parameter settings to the connected device can be adjusted, such as: groups setting and defining class IP address. Adjust the appropriate volume according to the site and arrange customized scheduling, such as: cleaning bells in the morning, class bells, or English listening exam... etc.
Installation via Cat.5 digital cable can keep a stable signal to ensure the sound quality of the broadcast.
With scalability, the old equipment can be linked to new system to use continuously to strengthen the efficiency of equipment use. It can also be connected with horn speakers to make every corner of the campus can hear the broadcast clearly.
The IP address installed in the classroom can not only receive campus broadcasts, but also can be used as a wireless microphone receiver in the classroom, making wireless teaching easy.
Under the trend of General English Proficiency Test, English listening tests can now be carried out in the classroom through the IP audio broadcasting system to improve efficiency.
