Description

The 4th generation Maxim is our flagship infrared classroom audio system that comes ready to support both in-person and hybrid learning.

It is the ultimate audio system for group presentation whether in a classroom, boardroom, or conference area. Its two channel receiver allows the simultaneous use of two wireless infrared microphones. Our Sapphire pendant is ideal for hands-free presentation while our IRH-35 handheld can be passed around the room for individual participation.

When connected to overhead speakers, the Maxim™ ensures that crystal clear sound is delivered to every seat in the room.

The Maxim has four auxiliary line inputs to integrate various media devices to supplement your presentation material for added engagement, plus connections for intercom, fire alarm, and security alert.

An ultrasensitive dome sensor mounted to the ceiling renders 100% reliable signal connectivity of the microphone throughout the room.

With our advanced infrared (IR) engineering, TeachLogic systems are less susceptible to outside interference and all transmission will be contained in the room. IR will not pass through a solid surface, thus eliminating transmission into an adjacent room and providing absolute security. What is said in the room stays in the room.
