The aptly named VoiceLink™ is the easiest way to add a crystal clear microphone to any existing sound system, sound bar, TV, or even a projector to broadcast the teacher’s voice in class. For classrooms with hybrid instruction, the dedicated audio output port connects to the teacher’s computer so students watching online can hear equally well. Each system comes with a microphone, ceiling sensor, and receiver.
