Product Details

Audio-Technica ATW-251 Freeway VHF UniPak Wireless System

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.

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 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.
