System 20 PRO

Overview

System 20 PRO

When we launched the System 10 PRO rack-mount receiver we took 2.4 GHz wireless microphone systems to a new level of functionality and convenience. Now, with the System 20 PRO we take it even further, offering a self-managing, plug-and-play 2.4 GHz system that’s scalable to 20 channels and delivers the same dependable, high-quality audio – regardless of where you set it up. Designed for hassle-free deployment, the system overcomes many challenges of conventional wireless microphones, such as frequency coordination, complex intermodulation calculations, and remote antenna cabling.

Capable of receiving up to four transmitters, the system’s ATW-R1440 receiver makes installation a breeze. Receiver units can remain docked in the half-rack chassis or be mounted remotely (up to 328 feet away) via Ethernet cable for added versatility. Up to five chassis can be linked using the included RJ12 cable, creating a stable, multichannel system with the simultaneous use of up to 20 channels. But the user is always free to choose the most effective operation mode for a given situation: Standard mode (10 channels) to minimize latency or HD mode (20 channels) to maximize channel count.

Seamless setup and management are controlled via Audio-Technica’s Wireless Manager software, which is capable of managing multiple UHF, 2.4 GHz and DECT wireless systems from a single screen. In addition, AES128 encryption comes standard, providing security and reliable operation. The transmitters included in each system are paired and ready to use out of the box, and offer all-day operation on a full charge.

Unmatched Audio Quality

Proven Digital Performance

When we first introduced the System 10 PRO wireless microphone system nearly a decade ago, it took 2.4 GHz technology to a level of reliability and convenience previously unattainable with wireless microphone systems. Now, with System 20 PRO we’ve taken it even further – doubling the channel capacity in half the bandwidth.
