Description

The Quantum™ II is a self contained sound system that supports two infrared wireless microphones for plug-and-play instruction. Simply remove it from the box, plug it in, and you’re ready to amplify learning!

Two wireless microphones can be used simultaneously–one for the teacher and one handheld for student participation or co-teaching. It can further expand the multimedia experience with its audio input and audio output ports. This can be connected to a computer, projector, TV, or virtually any audio source. In fact, it can synchronize the classroom audio with video conferencing applications like Zoom. This ensures that all listeners hear the teacher equally through the same microphone.

Its lightweight aluminum body makes it easy and convenient to locate where needed. A mounting bracket is included for wall mount and a mobile display mount applications. It can also be placed on a flat surface, attached to a tripod, or mounted with a display such as a TV or interactive whiteboard.

The Quantum II also features a connection for a second 8 ohm speaker, which doubles your coverage. Plus, its advanced infrared (IR) technology enables the use of multiple Quantum II units in the same room without interference.
