Each Atlas Learn Amplified Learning system can support up to two wireless microphones.The microphones can be set to either “A” or “B”, additionally one can be locked out to function as a student microphone with limited functionality if needed.Each wireless microphone has a volume control for adjusting the volume of that microphone relative to the user’s voice allowing it to be adjusted up or down so that the speaker can be clearly heard and understood.One of the most unique features of the Atlas Learn wireless microphones is their incorporation of a “PANIC” feature. This panic feature allows a teacher to signal the administration or security office in the event that an emergency situation arises in the classroom.On the MAGPIE microphone, the two red PANIC buttons can be depressed for three seconds to initiate the emergency signal.Both models can be used with optional wearable microphones and both models also include rechargeable batteries.
