Lavalier (lapel) microphones are available in many of the classroom spaces. These microphones clip onto a shirt or article of clothing about 6" away from the chin and have a body pack that can be clipped to a belt or placed into a pocket. The microphones are wireless so you can move around the space without contending with a wire. Volume and muting controls can be found on the control interface.
If you have more questions about the microphone usage or which microphone is in your classroom, submit a Classroom Consultation request.
