Audio-Technica AEW-4250D

AEW-R4100 receiver and AEW-T5400 cardioid condenser microphone/transmitter.

Audio-Technica’s 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 two hundred 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.

Features

• 200 selectable UHF channels per band and True Diversity reception for interference-resistant operation
• 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
• All components store up to five preset configurations, with customized "names" if desired
