The TeachLogic IRT-60 Sapphire is a compact and lightweight infrared microphone that can be worn around your neck or clipped to clothing, making it well suited for teachers, instructors, and lecturers. Its cardioid polar pattern delivers focused vocal clarity with minimal ambience while the built-in breath filter reduces plosives and the integral rubber shock suspension impedes vibrations. The internal lithium-ion battery provides up to eight hours of use and conveniently recharges via the supplied BRC-15 plug-in charger.
The ITR-60 Sapphire also features a 3.5mm stereo aux input to accommodate an external source such as a smartphone, an MP3 player, or a headworn mic. The mic gain and amplifier volume are adjustable, so you can effectively optimize the signal level. The power button doubles as an easy mute on/off function. When the IRT-60 Sapphire is used with a compatible amplifier/receiver, the switchable teacher priority automatically lowers the audio volume of aux/line inputs upon detection of incoming mic signal.
