The Samson Stage 412 is a frequency-agile, quad-channel wireless microphone system with four handheld dynamic microphones that transmit to a single rugged metal receiver. Each handheld features the Q6 dynamic mic element which provides crisp, clear sound and reliable VHF wireless performance for presentation, education, house of worship, karaoke and other applications with up to four performers. 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).
