Audio Technica.: 1800 Series Camera-mount UHF Wireless Systems- :.
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.

Microphone Power (ATW-T1802 Plug-on Transmitter): Provides power to condenser
microphones rated to
operate on 12V phantom power or less.
**Note: The 1800 Series offers UHF wireless operating frequencies 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
