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. The magnets can be replaced with included rubber feet.
