Audio Technica ATW-1421/BP894xCw-TH System 20 PRO Dual Wireless Headworn Mic System

Description

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

The Audio-Technica System 20 PRO delivers cutting-edge performance and exceptional convenience for professional 2.4 GHz wireless microphone applications. This self-managing, plug-and-play digital system supports up to 20 simultaneous channels while maintaining dependable, high-quality audio regardless of the installation environment. By eliminating complex setup processes such as frequency coordination, intermodulation calculations, and remote antenna cabling, it enables rapid deployment for live events, corporate AV, education, and installed sound systems.

At the core of the system is the ATW-R1440 receiver, capable of supporting up to four transmitters per channel for highly flexible microphone 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, allowing clean and adaptable installations across large venues or multi-room setups. Up to five chassis can be linked using the included RJ12 cable, creating a stable multichannel system with up to 20 channels operating simultaneously.

The system provides selectable operating modes to suit different requirements: Standard mode (up to 10 channels) to minimize latency, or HD mode (up to 20 channels) to maximize channel capacity. Configuration and monitoring are streamlined through Audio-Technica’s Wireless Manager software, which enables centralized control of multiple UHF, 2.4 GHz, and DECT wireless systems from a single interface.

Built-in AES128 encryption ensures secure and reliable wireless transmission. Transmitters are paired and ready for immediate use out of the box, providing all-day operation on a full charge. With OLED displays, auto-lock protection, and flexible output options, the System 20 PRO offers a dependable solution for demanding professional environments.
