Audio-Technica AEW-4240a Single Handheld UHF Wireless System Cardioid Dynamic Mic, Frequency-agile True Diversity

AEW-R4100 receiver and AEW-T4100a cardioid dynamic microphone/transmitter.

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 microphone/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) and 
  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 transmitters
  
• Locking battery door on UniPak body-pack transmitter
  
• All components store up to five preset configurations, with customized "names" if desired
