Product Overview
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 http://www.fcc.gov/cgb/wirelessmicrophones.

Product Details
Audio-Technica ATW-251 Freeway VHF Guitar Wireless System
The Audio Technica ATW-251 Freeway VHF Guitar Wireless System is designed to provide reliable performance, easy setup and clear, natural sound quality. The Freeway Wireless Microphone System includes the ATW-R250 receiver and the ATW-T201 body-pack 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.
ATW-R250 receiver
The ATW-R250 receiver includes a space-saving switching power supply that automatically adapts to changes in mains voltage. Unlike bulky linear power supplies, this switching power supply is lightweight and compact; it uses only a single outlet space.
ATW-T201 UniPak body-pack transmitter
The versatile ATW-T201 UniPak body-pack transmitter has both a high-impedance input for instruments, and a low-impedance input with bias connection for use with dynamic and electret condenser microphones. The ATW-T201 uses internal 9-volt batteries and has an Off/Standby/On switch, input Trim (level) adjustment, and battery-save switch.
