With UHF reception (996 frequencise 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 body-pack transmitter features a professional locking 4-pin connector compatible with all Audio-Technica Wireless Essentials microphones. 

Features

• 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
• 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
• 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, (the 1800 Series offers UHF wireless operating frequency in 25 kHz steps, while the 3000 Series offers UHF wireless operating frequencies in 125 kHz steps.  This means that not every frequency selectable on 1800 Series components will be selectable on the 3000 Series components.  Be certain to set each Transmitter-Receiver pair to identical frequencies).
