The ATW-1427 System 20 PRO Digital Wireless System includes one ATW-R1440 4-channel receiver and two ATW-T1407 desk stand transmitters, delivering professional 24-bit/48 kHz audio quality with reliable 2.4 GHz plug-and-play operation—free from TV interference. Users can select between Standard mode (10 channels) for reduced latency or HD mode (20 channels) for expanded channel capacity, ensuring flexibility for various setups. Receiver units can be docked or mounted remotely up to 328 feet away via Ethernet, and up to five chassis can be linked for larger configurations. Each channel supports pairing with up to four transmitters for seamless switching.
Designed for intuitive control and secure performance, the system features a System ID Display with real-time monitoring of RF levels, battery status, and link status. It integrates with Audio-Technica’s Wireless Manager software for centralized configuration and supports AES128 encryption and Syslog protocol for added security. OLED screens on transmitters and receivers offer clear readouts, while the auto-lock function prevents accidental changes. The desk stand transmitters are compatible with ATW charging docks for easy battery management and support mixed output modes—ideal for systems with limited input channels.
