The Audio-Technica System 20 PRO is engineered for live production, theater, corporate events, and broadcast applications where dual talent miking demands rock-solid wireless performance. The ATW-1421/L ships as a complete dual-lavalier system with two bodypack transmitters, two lavalier microphones, a single receiver chassis, and all necessary mounting and charging accessories. This system operates in the unregulated 2.4 GHz ISM band, eliminating frequency coordination complexity and TV interference concerns.

Sound professionals choose this system for its flexible channel architecture: Standard mode provides 10 simultaneous channels with minimal 2.8ms latency, while HD mode delivers 20 channels at 6.7ms latency. The receiver chassis docks into your equipment rack or mounts remotely up to 328 feet away via Ethernet, accommodating complex venue layouts. True diversity antenna design and AES128 encryption ensure reliable, secure signal transmission. Each receiver channel pairs with up to four transmitters, so talent can swap between bodypack and handheld configurations mid-show without re-tuning.

The system integrates with Audio-Technica's Wireless Manager software for centralized monitoring of RF signal strength, battery status, and system health across all linked units. OLED displays on transmitters and receivers provide at-a-glance confirmation of mode, channel, and power status, critical for fast-paced production environments.
