System 9 from Audio-Technica

A 4-channel frequency-agile wireless system, the System 9 is available in handheld, headworn, guitar, lavalier and body-pack configurations (other configurations available separately). The system offers 4 compatible user-switchable VHF channels (169.505, 170.245, 171.045, and 171.905MHz).

Each System 9 configuration includes a receiver and either a body-pack transmitter or handheld mic/transmitter. The ATW-R900a receiver is a non-diversity, single-channel receiver with advanced dipole antenna design for extended operating range, which improves operation by providing a ground element in addition to the usual signal element. It also offers volume control along with AF Peak, RF and Power indicator lights.
