Description

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

The Audio-Technica System 20 PRO sets a new benchmark for 2.4 GHz digital wireless microphone systems by combining advanced performance with exceptional ease of use. Designed as a self-managing, plug-and-play solution, it supports up to 20 simultaneous channels while delivering dependable, high-quality audio regardless of venue size or installation environment. By eliminating the need for frequency coordination, intermodulation calculations, and external antenna cabling, the system ensures fast, hassle-free deployment.

The system’s ATW-R1440 receiver can support up to four transmitters per channel, providing outstanding flexibility for multi-user scenarios. Receivers may remain docked within the half-rack chassis or be mounted remotely up to 328 ft (100 m) away using standard Ethernet cable, allowing clean and versatile system layouts. Up to five chassis can be linked using the included RJ12 cable, enabling stable operation of up to 20 channels simultaneously.

Users can choose between two operating modes depending on application needs: Standard mode supports up to 10 channels with minimal latency, while HD mode enables up to 20 channels for larger deployments. Centralized setup and monitoring are handled through Audio-Technica’s Wireless Manager software, which can control multiple UHF, 2.4 GHz, and DECT wireless systems from a single interface.

Security and reliability are ensured with built-in AES128 encryption. Transmitters arrive paired and ready to use out of the box, offering 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, live production, houses of worship, and installed sound applications.
