Audio-Technica ATW-R1440 System 20 PRO 4-Channel Digital Wireless Receiver – 2.4GHz Professional Audio System

The Audio-Technica ATW-R1440 is a professional 4-channel digital wireless receiver designed for the System 20 PRO 2.4GHz wireless microphone system. It is built for reliable, high-quality audio performance in small to medium venues, including conference rooms, educational institutions, houses of worship, broadcast setups, and live event installations.

This receiver is a half-rack, modular unit that can be easily mounted in a rack case or installed permanently. It works with compatible System 20 PRO transmitters such as bodypack and handheld microphones, allowing flexible multi-channel wireless setups for professional audio applications.

The ATW-R1440 supports up to 4 simultaneous audio channels, and can operate in different modes depending on performance needs. In standard mode it supports fewer channels with lower latency, while HD mode allows up to 4 channels in a single receiver with higher density operation, making it highly efficient for multi-mic environments.

Operating in the 2.4GHz digital wireless band, the system provides license-free operation and avoids traditional TV and UHF interference. It automatically scans and switches to clean frequencies, ensuring stable performance even in crowded wireless environments.

One of its key strengths is triple diversity reception technology, which combines space, time, and frequency diversity to significantly reduce dropouts and maintain strong signal integrity. This makes it extremely reliable for critical live sound applications.

The receiver delivers 24-bit / 48 kHz high-resolution digital audio, offering clear, natural sound with a wide frequency response of 20 Hz – 20 kHz (depending on microphone used). It also provides low latency (2.8ms to 6.7ms), ensuring real-time audio transmission without noticeable delay.

The front-panel OLED display shows real-time RF signal strength, audio level, battery status, and system information, making monitoring easy during live operation. It also includes Ethernet connectivity for remote placement of receiver modules up to 328 feet away, improving antenna reception flexibility.

With four balanced XLR outputs, AES128 encryption, and support for up to 20 transmitters per band (depending on environment), the ATW-R1440 is a powerful solution for scalable wireless microphone systems.

Overall, the ATW-R1440 is a high-performance, scalable, and interference-resistant digital receiver, designed for professional users who need stable multi-channel wireless audio with easy setup and strong reliability.
