The Dome Sensor features four selectable frequencies. More than two infrared microphones can be used in the same classroom at the same time. This is a great tool for team teaching, guest speakers, and itinerate teachers.
A light will appear when the sensor is powered on. The light will be “green” when the frequency switch is set to CH 1/2 and “orange” when the switch is set to CH 3/4.
