CONFIG & SETUP
Classroom Sound System
Our classroom sound systems are in two types: Infrared Microphone System and 2.4 GHz Microphone System. For individual classrooms such as music rooms, dance rooms, audio-visual rooms, multimedia learning rooms and other special rooms can be customized with suitable solutions. Welcome to contact us for details or make an appointment for product demonstration and site inspections.
Infrared Microphone System
The advantage of infrared microphone that infrared frequencies cannot penetrate walls, so they are very suitable for use in multiple venues at the same time. The usage of infrared microphones in school classrooms is very suitable that match its characteristics The following two combinations can be used for general classroom sizes:
1) Infrared sensor + Infrared microphone amplifier receiver + Speaker x 2
2) Infrared sensor + Infrared microphone receiver + Mixing amplifier + Speaker x 2
The difference in selecting infrared microphone receiver model that has built-in mixing and amplification functions. Users can choose the appropriate solution based on actual usage conditions and needs; for function details, please refer to the following system configurations.
2.4 GHz Microphone System
The 2.4 GHz microphone system adopts professional ID code encrypted transmission technology. It will not be interfered and the microphone can be easily and automatically pairing with the receiver. The pairing range of the microphone can also be adjusted to a suitable distance using the microphone setting function to suit the user’s usage habits and venue needs. Each receiver supports 2 wireless microphones at the same time without any operation settings. It is very user friendly.
Above microphone system is suitable for schools with limited budget or those who only need to replace or add an addition classroom microphone.
System CONFIGURATION
F.A.Q.
No; Infrared frequencies do not pass through the classroom walls and reflect in a straight line, it would be out of reception range when infrared frequency passing through windows. Even in two classrooms with windows facing each other, the installation position of the infrared sensor can be designed to avoid interference.
Generally, one pc of infrared sensor is enough to cover 99% of the usage area of a primary or secondary school classroom. For relatively large classrooms, such as geography rooms, physics lab, chemistry lab, etc., we recommend using two units of infrared sensor to fully cover the teacher’s movement range to achieve the best results.
Yes; our Linkx infrared mixing amplifier IRA-300 has the EchoGuard function, which can block the conversation echo of the video conference audio, so that when teacher is using the infrared microphone to speak, the students on site can hear it through the speaker, while the video conference The other parties can also hear at the same time through the conferencing software. Relatively, the other party in the video conference can also respond through the speaker so that both teachers and students can hear clearly.
Our 2.4GHz microphone system is specially designed for small venues usage. The straight-line usage distance (without obstruction) is about 30 meters; and the 2.4GHz itself will also be blocked and weakened by obstacles such as walls, so as long as the use channel of each classroom is well allocated (16 groups) can completely eliminate the interference.
Our 2.4GHz microphone system using professional ID code encrypted transmission technology. It will not be interfered and the microphone can quickly and automatically paired with the receiver. The pairing range of the microphone can also be adjusted to a suitable distance using the microphone setting function to match the user’s using habits and venue needs.
