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-15/IRR-30/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.
