Products Information
IRN-10 2-channel chest-worn transmitter
Feature
Chest-Worn IR Microphone/TransmitterA 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 IR 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) the microphone can be used the entire school day without recharging or changing batteries. If using the provided NiMH AA rechargeable batteries, they can be charged while installed inside the IRN-10, by connecting the BC-29 wall-charger (note that other battery brands will not be able to charge in-unit).
