Audio-Technica 4000 Series Frequency-agile True Diversity UHF Wireless Systems

Audio-Technica’s upgraded 4000 Series frequency-agile UHF body-pack and handheld wireless systems bring outstanding clarity and versatility to live performance, regional touring, fixed installations and more. At the heart of the 4000 Series is a rugged True Diversity half-rack receiver, the AEW-R4100, with 996 selectable channels offered in each of two available UHF bands.

Receivers from both the 4000 and 5000 Series may be linked; they may be monitored by the 5000 Series system software. The included IntelliScan™ feature automatically determines and sets the best available frequencies on all linked receivers.
