Azden Two-Channel IR Neck-Worn Xmitter w/ Built-in Mics

A lightweight, chest worn, microphone/transmitter, the IRN-10 comes with an adjustable lanyard. It is both a microphone and infrared transmitter which wirelessly "links" the teacher to the IRR-30P receiver. It has a specially designed internal microphone array which provides great sound pick-up. With two switchable channels, a teacher can go from classroom to classroom with the same microphone! With just two "AA" batteries (alkaline or rechargeable 1HR-3U only) the microphone can be used the entire school day without re-charging or changing batteries.
