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.
