ATW-1812Includes ATW-R1810 single-channel receiver and ATW-T1802 plug-on transmitter.
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.
For those using a single microphone, the single-channel 1800 Series systems include the ATW-R1810 single-channel receiver.
1800 Series wireless systems come equipped with a choice of plug-on and body-pack transmitters. The ATW-T1801 UniPak® body-pack transmitters feature a professional locking 4-pin connector compatible with all Audio-Technica Wireless Essentials® microphones. The ATW-T1802 plug-on transmitters feature a locking XLR connector for adapting dynamic and condenser microphones. Both transmitters offer selectable high and low transmission modes to conserve battery life/maximize power.
Additional 1800 Series features include automatic frequency scanning, Tone Lock™ squelch, back-lit LCD, soft-touch buttons, headphone monitor output with independent level control, and durable metal construction.
• 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**
