The Audio Technica ATW-1421, part of the System 20 PRO Series, is a wireless microphone system with two bodypack transmitters. Operating in the 2.4 GHz range, the system is licence free and totally TV interference free too.

The system consists of one Audio Technica ATW-R1440 wireless microphone quad receiver and two Audio Technica ATW-T1401 bodypack transmitters*.

The half rack width ATW-R1440 receiver set consists of an ATW-RC14 receiver chassis and docked ATW-RU14 receiver unit. This versatile design enables the receiver unit to be mounted remotely, if required, up to 328 feet away via Ethernet cable.

The ATW1440 is supplied with rack mount brackets to enable mounting of a single receiver or 2 receivers side by side in a 1U rack space.

The ATW-T1401 wireless microphone bodypack transmitter is powered by 2 alkaline, NiMH or Lithium AA batteries (not supplied) with an approximate run time of up to 15 hours, 14.5 hours or 29 hours respectively.

Building on the success of the System 10 PRO 2.4 GHz wireless microphone systems, Audio Technica now offer System 20 PRO with a self-managing, plug-and-play 2.4 GHz system that’s scalable to 20 channels and delivers the same dependable, high-quality audio.

Capable of receiving up to four transmitters, the System 20 Pro 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 minimise latency or HD mode (20 channels) to maximise channel count.

Audio-Technica’s Wireless Manager software enables seamless setup & management of multiple UHF, 2.4 GHz and DECT wireless systems from a single screen. In addition, AES128 encryption comes standard, providing security and reliable operation.

If purchasing a complete system, the transmitters are paired and ready to use out of the box and offer all-day operation on a full charge.
