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.

Multiple system configurations are available, with handheld vocal micorphone/transmitters and UniPak body-pack transmitters designed for use with lavalier, headworn and instrument microphones as well as electric guitars.

Features:

996 selectable UHF channels per band and True Diversity reception for interference-resistant operation
Available in two frequency bands:
541.500 - 566.375 MHz (TV Channels 25-30)
655.500 - 680.375 MHz (TV Channels 44-49)
IntelliScan feature automatically finds and sets best available frequencies on all linked receivers
Advanced digital Tone Lock squelch effectively blocks stray RF; the digitally encoded tone also communicates transmitter data for receiver display
Dual Compander circuitry processes high and low frequencies separately for unmatched audio quality
Link and coordinate multiple receiver channels
High-visibility white-on-blue LCD information display
Metal half-rack receiver chassis with mounting hardware
All transmitters offer rugged, ergonomic metal bodies, programmable features, soft-touch controls, and 10 mW/35 mW switchable RF power
Backlit LCD displays on transmitter
All components store up to five preset configurations, with customized "names" if desired
