TeachLogic IRT-60 overview

Well suited for classrooms and forums, the rechargeable IRT-60 Sapphire Infrared Transmitter/Microphone from TeachLogic offers the same aesthetic design and feature set as the IRT-55 Sapphire, but with an additional remote “Security Alert”, allowing teacher priority with instant attenuation of the line levels to work with the optional Forum 232 and Maxim III amplifiers.

The Sapphire can be worn with a lanyard or clipped directly to your neckline collar and offers a high level output, reliable connectivity, and great definition. With a built-in breath filter, the Sapphire can function as a pass-around hand microphone. Tapping the power button momentarily mutes the microphone, allowing for private conversations. The 3.5mm auxiliary input allows wireless playback of your iPod, while a three-position slide switch provides selections of low, medium, or high microphone volume levels. The included Lithium-Ion battery offers up to 9 hours use. The Sapphire IRT-60 ships with a BRC-15 wall charger and a breakaway lanyard.
