The perfect handheld
“pass-around” microphone for student participation,
this dual channel microphone/transmitter, operates on the channel
that the teacher is not using. It is powered by two
“AA” batteries (alkaline or rechargeable) and is
compatible with all Azden infrared models.
Both the IRN-10 and IRH-15c can recharge internal NiMH batteries
when a BC-29 wall-charger is used. There’s no need to remove
the batteries to recharge.
