• Audio Technica ATW-901A/L System 9 Lavalier Microphone System: ATW-901A/L
• Audio Technica Cardioid Condenser Clip-on Instrument Microphone: PRO35CW

ATW-R900a receiver and ATW-T901a body-pack 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. Featuring sleek, stackable, contemporary styling, System 9 is available in handheld, head-worn, 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 an advanced dipole antenna design for an 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 operation and clear, natural sound quality
• 4 selectable frequency-coordinated VHF channels
• Balanced XLR and unbalanced 1/4" output jacks enable use with a wide variety of audio gear
• Reliable performance and durable construction

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.
