Introduction of infrared sound reinforcement system

2. There are two types of infrared transmitters, namely chest hanging (neck hanging) transmitter KS-HG and handheld microphone KS-HD

Infrared transmitters are selected by teachers according to their preferences. They have excellent mobility and ease of use. The number of purchases is determined by the number of teachers that the school needs to use. The transmitter is completely universal and does not require frequency recognition and frequency modulation. Point, frequency point, can be used after starting

3. There are three types of microphones on the chest-hanging (neck-hanging) transmitter KS-HG, namely headset microphone (microphone MIC), collar microphone (microphone MIC), unilateral ear-hook microphone (microphone MIC) Teacher's preference determines which accessory to choose;

4. Infrared receivers are designed with different models according to the size and usage of the classroom. As described later, the model used at the time of purchase is completely determined by the situation of the classroom. The installation and debugging are also completely determined by the environment of the teacher. Determined by the number of classrooms to be used by the school;

5. The number and specifications of infrared transmitter and infrared receiving host do not require one-to-one correspondence. The company color pages or pictures put the two together, just for the convenience of introduction. You can buy them as a set or single purchase. However, when it is used, no matter which model of transmitter and receiver is in a classroom, one of them must be used at the same time;

6. In the introduction of all models, the models that do not mention dual-band are defaulted to single-frequency machines. The single-frequency machine is the most used and the most versatile model in China's actual teaching amplification; the dual-frequency machine is only interactive It is only used in the teaching mode or infrared wireless conference system. The dual-frequency receivers of our company are upgraded from the corresponding single-frequency receivers. There is not much difference in appearance alone, and the dual-frequency transmitters are also the same. The transmitter at frequency B is only made by changing the parameters based on the transmitter evaluated at A.
