TheATW-1421/L System 20 PROfromAudio-Technicais a two-person digital wireless audio system, featuring an ATW-RC14 half-rack receiver chassis equipped with a remote-mountable ATW-RU14 receiver unit along with two lightweight bodypack transmitters and two black omnidirectional lavalier microphones. It is well suited for rack-mounting in portable flight cases or for permanent installations in educational facilities, conference rooms, small- to mid-sized venues, and houses of worship as well as broadcast studios.
The easy-to-use system comes preconfigured at the factory, ready to operate right out of the box with no setup required. Three levels of diversity reception and automatic frequency selection provide seamless, reliable performance at a range up to 200′ with clear digital audio for presenters, lecturers, clergy, and performers.
Two Lightweight Bodypack Transmitters with Omni Lavalier Mics
This configuration includes two bodypack transmitters and two miniature MT830cW lavalier microphones with 4.6′ cables for hands-free wireless productions.
Each lavalier features a forgiving omnidirectional polar pattern that ensures consistent responsiveness regardless of the mic’s angle, and its 30 Hz to 20 kHz frequency response delivers accuracy across the frequency spectrum. Clothing clips and windscreens are included.
Each transmitter features a moisture-resistant Hirose 4-pin cW-style connector.
The transmitters provide up to 15 hours of use with two alkaline AA batteries and up to 29 hours with lithium batteries.
The transmitters are housed in lightweight chassis equipped with belt clips.
Adjust the input level to match the sensitivity of your microphone or audio source for distortion-free input.
With just a quick press, the power switch on the transmitter doubles as a mute function. This function can be locked out to prevent an accident.
Versatile 4-Channel Receiver
The flexible ATW-R1440 receiver offers two operational modes, depending on your needs. Standard mode provides 2 microphone channels at a latency of 2.8 ms, while HD (High Density) mode delivers 4 mic channels at a latency of 6.7 ms.
The chassis’ front-panel OLED screen provides visual status information including RF signal level, gain level, and the transmitter’s battery life.
A System ID number display indicates which transmitter is associated with a given receiver.
The rear panel provides 4 balanced XLR output connectors for compatibility with a wide range of pro audio gear.
The receiver module can be removed from the chassis and mounted up to 328′ away and connected via Ethernet cable for better antenna reception when necessary.
A 1/4″-20 thread allows for mounting the receiver module to a bracket, stand, and other fixture. The unit can also be permanently wall mounted using the included receiver unit holder.
The durable half-rack receiver chassis houses a modular receiver unit and can be mounted alone using the included mounting brackets and screws. Two chassis can be mounted side-by-side using the included joining plate, allowing eight wireless mic channels (in HD mode) to occupy a single 19″ rackspace for a compact multichannel installation.
Up to five chassis can be linked using RJ12 cables, creating a stable environment in which up to 20 wireless mics are operating simultaneously, with all receiving, transmitting, and frequency allocation coordinated to prevent audio dropouts.
Clear Digital Audio That’s Easy to Set Up and Operate
Digital Audio Quality
The System 20 PRO offers full-bandwidth, 24-bit/48 kHz digital audio with none of the audio artifacts associated with analog companding.
Automatic Frequency Selection
Just power up the components, and the receiver automatically seeks out a clean frequency and pairs up with the transmitter, saving you the hassle of scanning and syncing.
While in use, the system continually monitors activity in the 2.4 GHz Wi-Fi range and automatically switches to a clean frequency to avoid interference if necessary.
Pairing Multiple Transmitters
Each receiver channel can be paired with up to four transmitters, allowing users to instantly switch between different transmitter configurations. This is useful in situations when you have multiple speakers, one after another, and you need to have them miked up and ready to go. All you’ll have to do is turn one transmitter off and the next one on.
Remote Control from Computer
Wireless Manager is a dedicated software that supports the wireless operation of Audio-Technica products. Connecting the receiver to a computer running Windows or macOS allows you to monitor the status of and control the receiver.
You can configure device settings in an offline manner and even import settings by establishing an online connection with a device. Certain settings, including detailed mix outputs, EQs, and compressor parameters are only adjustable via Wireless Manager.
Three Levels of Diversity Assurance to Avoid Dropouts
Triple Diversity Reception Maximizes Wireless Signal Integrity
Space Diversity: the receiver compares the signal showing up at its two antennas and chooses the strongest one.
Time Diversity: the transmitter sends the digital signal in two imperceptibly different time slots and compares the two.
Frequency Diversity: the digital audio is sent over two different frequencies at the same time and the system chooses the cleaner one.
For optimal performance, users are encouraged to maintain as direct a line of sight as possible between the transmitter and receiver.
2.4 GHz Wi-Fi Band
Unlike traditional analog wireless systems, the System 20 PRO operates in the 2.4 GHz ISM band, away from interruptions and dropouts caused by TV and radio channel interference.
Add Functionality to Your System
Audio-Technica offers a variety of headset, instrument cable, and handheld microphone options to adapt your System 20 PRO as your needs evolve.
Vocalists/Presenters
The ATW-T1402 handheld transmitter/mic is available for presenters and performers who prefer the flexibility of a handheld microphone.
Video Conferencing
The ATW-T1406 boundary transmitter/mic is designed for tabletop use, ideal for applications such as video-conferencing where minimum visibility is required.
Conferences/Boardrooms
The ATW-T1407 base transmitter can be used with a gooseneck mic on a table for situations where wired mics are impractical.
Guitarists
The AT-GcW guitar cable lets you connect the bodypack transmitter to a guitar or bass.
