CONTENTS
This unit is a receiver which integrates both a sensor receiving infrared light from the infrared wireless microphone (MTD-09,
MHH-09) and a receiving component. Integration of a receiving component and a sensor allows an infrared wireless micro-
phone system to be simply constructed by mounting this unit on the ceiling. Use of the supplied conversion box provides
extension between the receiver and an amplifier, and accordingly leads to flexibility in installation locations.
This unit also includes the feedback blocker to decrease feedback generated when the microphone and speaker approach
each other.
•
As the unit uses infrared light, it is not affected by interference from adjacent rooms.
•
The microphone is available as a handheld model (MHH-09) and as a pendant “teardrop” model (MTD-09). The
2-channel microphone of this unit and the audio level of the line can be controlled with the pendant type.
