Audio-Technica ATW-251/H 200 Series Freeway VHF Headworn Wireless System

ATW-R250 receiver, ATW-T201 transmitter and PRO 8HEcW headworn microphone.

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.

• Easy operation and clear, natural sound quality


• Reliable performance and durable construction


• Advanced dipole antenna system for extended operating range


• Power, RF, and AF Peak indicators


• Volume control, ¼” output jack and space-saving power supply


• Rugged unidirectional dynamic element on handheld microphone/transmitter


• Variable microphone trim control and easily accessible On/Standby/Off switch on transmitters


• Professional locking connector on UniPak® body-pack transmitter
