ATW-R900 receiver and ATW-T901 UniPak transmitter with omnidirectional lavalier microphone. 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.
Each System 9 configuration includes the ATW-R900 receiver. The ATW-R900 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-R900 also offers volume control along with AF Peak, RF and Power indicator lights.
