The IR-300M is a hands-free infrared wireless microphone. It eliminates problems with interference or eavesdropping, allowing simultaneous use in adjacent conference rooms or school classrooms. Since infrared wireless microphone system uses a frequency band that does not interfere with that of the TS-800 and TS-900 series infrared conference system, both systems can be simultaneously installed in the same location.
