1800 Series

Overview

1800 Series

With UHF reception (996 frequencies user-selectable in 25 kHz steps), Audio-Technica’s 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.

CONSUMER ALERT Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website at www.fcc.gov/cgb/wirelessmicrophones.
