1)the voice results better;
2)suitable for classroom holding 50-120 persons;
3) no string frequency.
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.
l The host and auxiliary speakers design makes sound homogeneous, the two speakers should be connected . has an out-fitted receiver;
l Fitted in a 50~120 persons of room, the received area is 200sqm .
l Only a bottom to control the volumn without audio input or output. No wire microphones are available.
l Transmitter can be easily fit to any infrared receiver.Convenient to control.
