Wireless systems have an obvious benefit: freedom of movement onstage. Unencumbered by instrument or microphone cables, or the need to stay close to monitor speakers, you’re free to roam the performance space. For active performers and presenters this can be a big advantage. Wireless systems also can be faster to set up, and help minimize the clutter of cables, mic stands, and floor monitors that crowd performers. Of course, their benefits aren’t limited to stages; you’ll find wireless systems in houses of worship, lecture halls, theaters, dance and exercise studios—anywhere presenters, instructors, or performers are looking for freedom of movement.This microphone group have one to one, one to two, one to four channel.
