Availability: InStock

The Audio-Technica ATW-902A System 9 Handheld Wireless System is a comprehensive wireless audio solution designed for handheld applications. This system facilitates reliable audio transmission by combining the ATW-R900a receiver with the ATW-T902a handheld dynamic unidirectional microphone/transmitter. The package includes an AT8456a Quiet-Flex stand clamp to ensure the system is ready for immediate mounting and use.

Core System Components

The ATW-902A package consists of dedicated hardware engineered for synchronized wireless operation.

ATW-R900a Receiver

The ATW-R900a receiver acts as the primary signal processing hub for the System 9. It captures the wireless signals sent from the handheld transmitter to provide a stable and consistent audio feed for connected sound systems.

ATW-T902a Handheld Transmitter

The ATW-T902a integrates a microphone and a transmitter into a single handheld unit. This component features a dynamic microphone element that provides reliable performance in diverse environments. The unidirectional polar pattern focuses on the primary sound source directly in front of the microphone, which effectively minimizes background noise and reduces the potential for feedback during operation.

Mounting and Accessories

The inclusion of the AT8456a Quiet-Flex stand clamp enhances the utility of the ATW-902A system. This accessory allows for the secure mounting of the ATW-T902a transmitter onto standard microphone stands, providing flexibility for presenters and performers who require hands-free operation or a stable resting position for the microphone.
