EJ-900AI Infrared Soundfield System

Clear sound projection is essential to pupils’ learning. Students will perform well when they can hear every word clearly pronounced by teachers. A good Soundfield System can do more than that by delivering clear voice projection, offering better verbal recognition, and improving learning behavior – this is what EJ-900AI will provide. An additional benefit that IR technology will give is teachers can get rid of the setting of microphone from room to room.
