Audio Technica ATW-1421 System 20 PRO Dual Wireless Beltpack System

Description

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

The Audio-Technica System 20 PRO advances 2.4 GHz wireless microphone technology with exceptional scalability, reliability, and ease of deployment. Designed as a self-managing, plug-and-play digital system, it supports up to 20 simultaneous channels while delivering consistent, high-quality audio regardless of installation environment. By eliminating traditional challenges such as frequency coordination, intermodulation calculations, and external antenna cabling, the system enables fast, hassle-free setup.

At the core of the system is the ATW-R1440 receiver, capable of supporting up to four transmitters per channel for flexible multi-user configurations. Receivers can remain docked in the half-rack chassis or be mounted remotely up to 328 ft (100 m) away via Ethernet cable, allowing clean installations across large venues or distributed systems. Up to five chassis can be linked using the included RJ12 cable, enabling stable operation of up to 20 channels simultaneously.

The system offers selectable operating modes to match application needs. Standard mode supports up to 10 channels with minimal latency, while HD mode allows up to 20 channels for larger deployments. Setup and monitoring are streamlined using 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 are paired and ready to 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, live production, houses of worship, and installed sound environments.
