A reliable and easy to use wireless system for the working musician.
The Audio-Technica ATW-251 Freeway VHF UniPak Wireless System is designed to provide reliable performance, easy setup and clear, natural sound quality. The Freeway VHF Lavalier Wireless System includes the ATW-R250 receiver, and the ATW-T201 body-pack transmitter. A novel dipole antenna system on the receiver improves operation by providing a ground element in addition to the usual signal element.
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 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. A cable for connecting your source to the transmitter is not included because this UniPak version can be used with a variety of sources.
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 FCCs wireless microphone website at: www.fcc.gov/cgb/wirelessmicrophones.
