Audio-Technica ATW-902a System 9 Wireless Handheld Microphone System

Pro-quality wireless system combining rock-solid performance with easy setup and clear, natural sound quality.

Part of Audio-Technica's System 9 series of professional wireless mic systems, the ATW-902a configuration includes an ATW-R900a Receiver packaged with an ATW-T902a handheld dynamic unidirectional mic/transmitter and includes an AT8456a Quiet-Flex stand clamp.

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. It also offers volume control along with AF Peak, RF and Power indicator lights. This system offers four compatible user-switchable VHF channels (please see below).

System 9 from Audio-Technica

A 4-channel frequency-agile wireless system, the System 9 is available in handheld, headworn, guitar, lavalier and body-pack configurations (other configurations sold separately). The system offers 4 compatible user-switchable VHF channels (169.505, 170.245, 171.045, and 171.90MHz).

Each System 9 configuration includes a receiver and either a body-pack transmitter or handheld mic/transmitter. The ATW-R900a receiver 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. It also offers volume control along with AF Peak, RF and Power indicator lights.
