Usually arrives in 5-9 business days.
The ATW-1423/L is a versatile, high-performance digital wireless solution designed for professional audio applications. The system includes one ATW-R1440 4-channel receiver, one ATW-T1402 handheld microphone transmitter, one ATW-T1401 body-pack transmitter, and one MT830cW lavalier microphone—providing both handheld and lavalier options in a single package.
Operating in the interference-free 2.4 GHz range, the System 20 delivers clear, 24-bit/48 kHz digital audio and allows users to switch between Standard mode (10 channels) and HD mode (20 channels), optimizing for either minimal latency or maximum channel count. The receiver channels can be docked in a chassis or remotely mounted via Ethernet cable, supporting distances up to 328 feet. Up to five receiver chassis can be linked and used simultaneously for expanded setups.
Each channel supports up to four paired transmitters, making it easy to switch between different microphone configurations. OLED displays on both transmitters and receiver provide clear status readouts, while built-in AES128 encryption ensures secure transmissions. The system is compatible with Audio-Technica’s Wireless Manager software for advanced configuration and control and features an auto-lock function to prevent accidental settings changes.
Ideal for live performance, education, and corporate environments, the ATW-1423/L combines flexibility, reliability, and professional-grade audio in a comprehensive wireless solution.
