Audio Technica ATW-1441/AT831cW System 20 PRO Quad Wireless Lavalier Mic System

Description

Audio-Technica System 20 PRO 2.4 GHz Digital Wireless Microphone System

The Audio-Technica System 20 PRO takes 2.4 GHz wireless microphone systems to a new level of functionality and convenience. This self-managing, plug-and-play digital platform can scale up to 20 simultaneous channels while maintaining dependable, high-quality audio performance wherever it is installed. Designed for hassle-free deployment, it removes the complexities of traditional wireless systems such as frequency coordination, intermodulation calculations, and remote antenna cabling.

At the core of the system is the ATW-R1440 receiver, capable of supporting up to four transmitters per channel for flexible configurations. Receiver units can remain docked in the half-rack chassis or be mounted remotely up to 328 feet (100 meters) away via Ethernet cable, offering excellent installation flexibility. Up to five chassis can be linked using the included RJ12 cable, enabling a stable multichannel setup with up to 20 channels operating simultaneously.

The system allows users to choose the optimal mode for their application: Standard mode (up to 10 channels) to minimize latency, or HD mode (up to 20 channels) to maximize channel capacity. Setup and management are streamlined through Audio-Technica’s Wireless Manager software, which can control multiple UHF, 2.4 GHz, and DECT wireless systems from a single screen.

Built-in AES128 encryption ensures secure and reliable wireless transmission. Transmitters are paired and ready for immediate use out of the box and provide all-day operation on a full charge. With OLED displays, auto-lock protection, and flexible output options, the System 20 PRO is ideal for corporate AV, education, houses of worship, live events, and permanent installations.
