Enjoy Worry-Free Pristine Sound With The Audio-Technica System 9 Wireless Lavalier Microphone System

Audio-Technica's System 9 is a four-channel frequency-agile wireless system designed to provide rock-solid performance along with easy setup and clear, natural sound quality. Featuring sleek, stackable, contemporary styling, System 9 has compatible options for handheld, headworn, guitar, and body-pack configurations as well. The system also offers four compatible user-switchable VHF channels (169.505, 170.245, 171.045, and 171.905 MHz)

This System 9 configuration includes the ATW-R900a receiver and ATW-T901a body-pack transmitter with a MT830 omnidirectional lavalier microphone. The ATW-R900a is a non-diversity, single-channel receiver with advanced dipole antenna design for extended operating range, which improves operation by providing a ground element in addition to the usual signal element. The ATW-R900a also offers volume control along with AF Peak, RF and Power indicator lights.

Designed to be worn as a lavalier or hidden in loose clothing or in the hair, the MT830 omnidirectional condenser microphone provides high intelligibility for lecturers, stage/TV performers, and singers. The mic's wide-range capability ensures clean, accurate reproduction.
