IR-200M Y 4QD00

The IR-200M  Y 4QD00 is a handheld 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. Possible to use with either Channel  A / B / 1 / 2.
