The ATW-1421/L System 20 Digital Wireless System includes one ATW-R1440 4-channel receiver, two ATW-T1401 body-pack transmitters, and two MT830cW lavalier microphones. Operating in the interference-free 2.4 GHz range, it delivers crystal-clear 24-bit/48 kHz digital audio. Users can switch between Standard (10 channels) and HD (20 channels) modes to optimize latency or channel count. Each receiver channel pairs with up to four transmitters, while remote mounting and linking of up to five chassis provide flexible configuration. Features include AES128 encryption, OLED displays, sweat-resistant connectors, and compatibility with Wireless Manager software. Ideal for professional applications requiring reliable, high-performance wireless audio.
