Product Description
Audio-Technica 200 Series Freeway VHF Wireless System: ATW-251G Wireless System with Omnidirectional Lavalier Microphone
Audio-Technica’s Freeway® 200 Series Wireless Systems are designed to provide reliable performance, easy setup and clear, natural sound quality. Available in handheld, headworn, guitar, lavalier and body-pack configurations, the 200 Series Freeway Wireless Systems are single-channel, fixed-frequency systems available in three VHF frequencies (see below).
Each 200 Series Freeway Wireless System includes the ATW-R250 receiver and either a body-pack transmitter or handheld microphone/ transmitter. The ATW-R250 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. The ATW-R250 also offers volume control along with AF Peak, RF and Power indicator lights.
- Easy operation and clear, natural sound quality

CONSUMER ALERT Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website at www.fcc.gov/cgb/wirelessmicrophones.
