Audio Technica ATW3131A UHF Lavalier Wireless System

With automatic frequency scanning to find and set the best available channel, 200 selectable UHF channels, true diversity protection from RF hits and dropouts, soft-touch controls, easy setup and great sound, the 3000 Series wireless delivers truly professional performance.

The versatile UniPak body-pack transmitter features a secure 4-pin locking connector compatible with a wide range of microphones, as well as a guitar cable. A 3-position sliding cover on the transmitter's control panel prevents accidental shut-off or channel-switching.

Features
Automatic frequency scanning

200 PLL-synthesized channels per band selectable via soft-touch controls on receiver and transmitter

Available in two frequency bands:
