• Audio Technica System 901 Transmitter and Bodypack: ATW-901A/G
• Audio Technica Cardioid Condenser Clip-on Instrument Microphone: PRO35CW

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 is available in handheld, headworn, guitar, lavalier and body-pack configurations. The system offers four compatible user-switchable VHF channels (169.505, 170.245, 171.045, and 171.905 MHz). 

Each System 9 configuration includes the ATW-R900a receiver and either a body-pack transmitter or handheld microphone/transmitter. 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.

• Easy to use, with clear and natural sound quality
• 4 frequency-coordinated selectable VHF channels
• 1/4" balanced and unbalanced XLR output connectors compatible with a wide variety of audio adapters
• Reliable performance and rugged manufacturing
• Advanced dipole antenna system to increase operating range

Designed for sax, toms, brass and percussion, the PRO35cW excels in high-SPL applications and is ideal for active stage performances. Its extended frequency response captures subtle nuances of the performance. The included UniMount^® clip permits accurate positioning and provides shock resistance while protecting the element. The microphone's cardioid polar pattern reduces pickup of sounds from the sides and rear, improving isolation of the desired sound source.
