ATW-1421 System 20 PRO Dual Body-Pack System

The ATW-1421 System 20 PRO Dual Body-Pack System offers unmatched wireless audio performance, designed for professionals who demand exceptional sound quality and reliability. With digital 24-bit/48 kHz wireless operation, this system ensures the highest audio fidelity, providing crystal-clear sound in any setting. Its plug-and-play functionality operates in the 2.4 GHz range, free from interference typically caused by television signals, making it ideal for a variety of environments where interference is a concern.

The system features an adaptable channel configuration, allowing users to switch between Standard mode, which offers 10 channels, and HD mode, which provides up to 20 channels. This flexibility helps minimize latency or maximize channel count based on your specific needs. Additionally, the receiver units can be docked directly in the chassis or mounted remotely up to 328 feet away via an Ethernet cable, offering enhanced versatility and placement options.

Up to five chassis can be linked and used simultaneously, making the ATW-1421 System 20 PRO perfect for larger setups or complex audio environments. Each receiver channel supports pairing with up to four transmitters, allowing for easy switching between different configurations. The chassis features a System ID Display that shows key information such as RF signal level, system ID, transmitter battery level, and system link status, ensuring you have all the data you need at a glance.

The system includes a range of additional features to enhance usability and security. It comes with both short and long rack ears, which can be combined to secure two chassis in a full rack space. Compatible with Audio-Technica’s Wireless Manager software, it allows for centralized management of system settings and operations. The auto-lock function prevents unintended operations, while AES128 encryption ensures secure transmission. Additionally, the system is compatible with Syslog protocol and supports project-based configuration and monitoring through Wireless Manager.

Each transmitter and receiver is equipped with an OLED screen for clear readout of settings and alerts. The body-pack transmitter features a water- and sweat-resistant cW-style connector for secure attachment to lavalier mics, headworn mics, and cables with cW-style locking 4-pin connectors. Charging is convenient with compatibility for ATW-CHG3/ATW-CHG3a and ATW-CHG3N/ATW-CHG3Na charging docks, allowing for easy recharging of NiMH batteries. The system also supports mixed output, ideal for situations with limited input channels.
