Two wireless microphones can be used simultaneously–one for the teacher and one handheld for student participation or co-teaching. It is lightweight and convenient to sit on a desk, mount on a wall (mount bracket included), or attached to a standard microphone stand or tripod via a threaded attachment on the bottom.
