Includes ATW-R1820 dual-channel receiver, ATW-T1801 UniPak® body-pack transmitter, ATW-T1802 plug-on transmitter and a lavalier microphone

With UHF reception (996 frequencies user-selectable in 25 kHz steps), Audio-Technica’s new 1800 Series camera-mount wireless microphone systems provide extremely flexible, professional, and easy-to-use portable wireless solutions. The 1800 Series is available in dual-channel and single-channel systems.

For simultaneous operation of two microphones, dual-channel 1800 wireless systems include the ATW-R1820 dual receiver with two completely independent receiver channels in a single unit. Dual balanced outputs enable signals to be mixed, or independently assigned to each output. Independent audio level controls provide flexible audio mixing and monitoring possibilities. 

Two completely independent receiver channels in a single unit, for simultaneous operation of two microphones (dual-channel systems)

Compact receiver is easy to mount on a camera

• UHF reception with 996 frequencies selectable in 25 kHz steps
• Automatic frequency scanning for easy selection of open channels
• Tone Lock™ squelch system eliminates interference when transmitter is off
• Two independent balanced outputs (dual-channel systems)
• Headphone monitor output with independent level control
• Battery fuel-level indicators on transmitters and receiver
• Soft-touch controls for easy frequency selection
• True Diversity operation for resistance to multi-path interference and dropouts
• LCD frequency and battery status display with backlight
• Antenna and AF Peak LED indicators
• Dual-channel receiver can operate in single-receiver mode to extend battery life when only one   audio channel is in use (dual-channel systems)
• Transmitters operate in low or high transmission modes to conserve battery life/maximize power
• Easy, user-friendly operation
• Clear, natural sound quality
• Powered by AA batteries
• System components of the 1800 Series and 3000 Series Wireless Systems can be used interchangeably
