Samson has been dedicated to driving wireless innovation, always striving to make it easier for performers everywhere to cut the cord. The Stage 412's frequency-agile design offers four channels with six operating frequencies per channel across a 173MHz–198MHz frequency range to choose from. In addition, the system's IR sync function allows users to wirelessly match each transmitter to a receiver channel's operating frequency in no time. A 200' operating range provides ample freedom for any presenter or performing Group, while each mic transmitter provides exceptional battery life of up to 10 hours via two AA batteries (not included).
