Built for seamless integration into professional AV setups, this half-rack (19") stationary receiver offers reliable wireless audio transmission, smart management features, and flexible connectivity. Its standout feature is the bi-directional communication, allowing full remote control of transmitter settings directly from the receiver. With automatic frequency and interference management, it ensures a stable, high-quality signal without user intervention which is ideal for business presentations, educational institutions, and conference environments.
