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 Dual Sapphire IRT-60 ships with a BRC-60 drop-in battery charger and Pre-programmed Wall mount control panel includes Bluetooth (CPS-120)

TeachLogic BRC-60 overview

The BRC-60 Drop-in Charger from TeachLogic is used to power up one IRH-35 handheld transmitter and up to two IRT-55/60 Sapphire transmitters. The BRC-60 can also be powered directly from the USB port on Maxim III and Spectrum III amplifiers.

The addition of a set of magnets on the bottom of the charger allows rock solid attachment to a WM-400 wall Cabinet (sold separately). Using this wall cabinet allows you to free up valuable space for other classroom items and makes for a very clean install by hiding all the cables.
