• Audio Technica 901 Wireless Headworn Microphone System: ATW-901/H
• Audio Technica Cardioid Condenser Clip-on Instrument Microphone: PRO35CW

The Audio-Technica system 9 is an agile wireless system with a four-channel frequency designed to give a solid presentation with simple setup and clear and natural sound quality. Presenting an elegant, stackable, and contemporary style, System 9 is available in manual mode, with headband, guitar, lavalier, and body-pack configurations. The system offers four user-compatible VHF channels that can be changed (169.505, 170.245, 171.045, and 171.905 MHz).

Each System 9 configuration includes the ATW-R900 receiver and a body-pack transmitter or a handheld microphone / transmitter. The ATW-R900 is a single-channel diversity receiver, with advanced dipole antenna design for an extended operating range, which improves the performance it provides is a terrestrial factor, in addition to the usual signal element. The ATW-R900 also offers volume control along with the AF Peak, RF and Power indicator lights.

• Easy to operate and clear and natural sound quality
• 4 frequently coordinated selectable VHF channels
• Balanced XLR and 1/4 "unbalanced output connectors allow use with a variety of audio equipment
• Reliable presentations and durable construction
• Dipole antenna system for extended 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.
