1)Infrared light transmit signal,
3)good quality and low price.
Here is the Infrared Advantages:
1. Infrared light transmit signal,High Security,Interference Resistence and Against String Frequency
Infrared (IR) is short-range wave, cannot penetrate walls,which solve the string problems between the classrooms. It can realize that many sets of equipments used in many rooms simultaneously, so it is safe and has good isolation.
2. Emitter can be equiped with any receiver,Operate Conveniently
We can use the same frequency in the different rooms beacause of no string frequency. teachers can use the same microphone in different rooms ,so it is conveniet to manage.
3.Using light refraction to achieve 360 ° sensing in 30 m, it there are barrier and turn of the teachers ,the transmitting distance can be 10m.
4.Away from the electromagnetic radiation and interference, create a healthy, environmental -protected, health, green campus.
1. Set the host,infrared receiver, amplifier, speakers as a whole,this portable design is easy to carry and operate.
2. Suitable 50-80 (area less than 100 square meters) of the classroom
3. Can be hanging on the wall or carried by teachers.
4. Has the functions of audio output, input, high and low volume , digital echo
5. Along with audio input, audio output all the way, a group of wire microphone input, master volume and high-bass independent adjustable, with digital reverb function.
