Model type: KS168-C

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 degree 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.

 

Features:

1. Amplifier, speaker, integrated in a compact loudspeaker, receiver outfitted.

2. The host machine adopts wall-mounted installation, output power is 50W.

3. Suitable for 50 ~ 80 or classroom, receiving area is 80 to 120 sqm which needs to broadcast.

4.Set a campus radio output voltage signal access, the terminal can replace the campus radio speakers, reducing the number of classroom speakers, radio signal has priority function.

5.Wireless microphone volume and broadcast signal volume are both independently adjustable.
