The Audio-Technica ATW-1426 Dual Boundary Wireless Microphone System is a System 20 Pro 2-channel wireless setup featuring an ATW-R1440 rack-mount receiver chassis, an ATW-RU14 receiver unit, four 2.4 GHz antennas, and two ATW-T1406 boundary transmitters.

The Audio-Technica ATW-1426 Dual Boundary Wireless Microphone System is a professional digital wireless solution that combines high-fidelity audio with flexible installation options. This system includes one ATW-R1440 4-channel receiver chassis and two ATW-T1406 boundary microphone transmitters, designed for clear, dependable performance in diverse environments.
This system utilizes 24-bit/48 kHz digital wireless technology to ensure superior sound quality. Operating in the 2.4 GHz range, the ATW-1426 remains completely free from TV interference. Users can choose between two operational modes: Standard mode, which supports 10 channels with minimized latency, and HD mode, which supports up to 20 channels to maximize the available channel count in high-density environments.
The ATW-R1440 receiver chassis provides versatile mounting options to suit specific venue requirements. Receiver units can be docked directly in the chassis or mounted remotely up to 328 feet away using an Ethernet cable. For larger applications, users can link up to five chassis to operate simultaneously. The chassis is equipped with a System ID Display that provides real-time information on RF signal levels, system ID, transmitter battery levels, and system link status.
Each receiver channel can be paired with up to four transmitters, allowing for instant switching between different hardware configurations. The system is compatible with Audio-Technica’s Wireless Manager software, enabling centralized management, configuration, and monitoring of device settings. To ensure secure transmission, the ATW-1426 utilizes AES128 encryption. Additionally, an auto-lock function prevents accidental power-off or unintended changes to the channel selection.
Both the transmitters and receivers feature integrated OLED screens for clear readouts of key settings and system alerts. The system supports the Syslog protocol for detailed monitoring and allows users to save device settings as projects within the Wireless Manager software. For installations with restricted input availability, the system supports a mixed output mode to consolidate signals.
The half-rack receiver chassis comes with a short and long rack ear. These components can be utilized as a joining plate to secure two chassis within a single full rack space. The boundary transmitters are built for stability on flat surfaces, while the included antennas and AC adapter ensure the system is ready for immediate deployment.
