RM80

RM80 tries to restore the natural high-volume voice, there is no noise when the distance changes, natural noise reduction, voice pickup, and non-inductive sound reinforcement.
Because it does not need to be worn, the teacher did not change the waist and neckline of the clothes that are easy to wear the lavalier microphone before the class. During operation, RM80 did not make any whistling. In the process of using, the teacher walks freely back and forth, writing on the blackboard and body language freely cooperate with the lecture, freeing both hands and teaching distance. Usually when the teacher bends down to pick up the dropped items, the change of the distance to the microphone will cause the lavalier microphone to scream, and there is no noise when the distance to the RM80 is changed. During the course of the class, the teaching video played and the student's mobile phone rang did not cause signal interference similar to that of wireless microphones, and the sound amplification was smooth. Teachers go to class for a long time, in order to protect their voices, their voices are generally low, and when students speak, their voices are difficult to communicate clearly because of the long distance. RM80 strives to restore natural high-volume voice, natural noise reduction, voice pickup, and non-inductive sound reinforcement, while protecting teachers’ voices and students’ ears.
