Leveraging Panasonic's 20-year experience in DECT wireless audio communications, the WX-SR200P 1.9 GHz digital wireless microphone system is the best-in-class solution for classroom or corporate presentations providing low latency for hybrid in-room/virtual presentations.  Panasonic's digital wireless microphone system is easy to set up, easy to integrate with third-party control systems (such as Crestron, Extron, and Q-SYS) and easy to use.  Setup is a breeze - the wireless microphones pair wirelessly with Panasonic's digital wireless mic receiver and assigns channels automatically, eliminating the need for manual channel assignment. The system can be expandable to suit a variety of spaces, from small classrooms, medium sized classrooms / conference rooms, to large auditoriums. Up to 8 separate antennas (per receiver) can be mounted to the wall or the ceiling in the room and connected via CAT5 back to the receiver locked away in a cabinet or closet and multiple digital wireless microphone receivers can be installed to add wireless microphone channels to the room
