Audio-Technica's Freeway 200 Series Wireless Systems are designed to provide reliable performance, easy setup and clear, natural sound quality. Each 200 Series professional VHF wireless system includes a receiver and either a body-pack transmitter or a handheld microphone/transmitter on a specific crystal-controlled frequency. A novel dipole antenna system on the receiver improves operation by providing a ground element in addition to the usual signal element.
