TOA Infrared Microphone Hands-Free Type IR-300M

This is a hands-free infrared microphone that uses an infrared cordless system. There is no need to worry about interference or eavesdropping, and it can be used simultaneously in adjacent classrooms and conference rooms. Since it uses a frequency band that does not interfere with each other, it can be used in conjunction with an infrared conference system (TS-800/900 series) (channels A and B only). It has an external microphone input, so it can be used in combination with a tie clip microphone or headset microphone.
