Operating in the 2.4 GHz range, it's free from TV signal interference, making it perfect for various environments. The system offers an adaptable channel configuration. You can switch between Standard mode with 10 channels and HD mode with up to 20 channels, allowing you to either minimize latency or maximize the channel count according to your needs. The receiver units can be docked in the chassis or mounted remotely up to 328 feet away via an Ethernet cable, providing great versatility. Up to five chassis can be linked and used at the same time, which is ideal for large setups. Each receiver channel can pair with up to four transmitters for easy configuration switching. The chassis has a System ID Display that shows important information like RF signal level, system ID, transmitter battery level, and system link status at a glance. It also comes with short and long rack ears, and two long ears 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. The auto - lock function prevents accidental operations, and AES128 encryption ensures security. It's also compatible with the Syslog protocol and lets you configure, monitor, and save device settings as projects in the Wireless Manager. Both transmitters and receivers have OLED screens for easy readout. The body - pack transmitter has a water - and sweat - resistant cW - style connector, and its charging terminals work with ATW - CHG3/ATW - CHG3a and ATW - CHG3N/ATW - CHG3Na charging docks.

Using the Audio - Technica ATW - 1421 system is a breeze. First, decide whether you need the Standard mode or the HD mode based on your requirements. If you want to reduce latency, go for Standard mode; if you need more channels, choose HD mode. Connect the receiver units to the chassis or mount them remotely using an Ethernet cable up to 328 feet away. Pair the transmitters with the receiver channels, and you can pair up to four transmitters with each channel. When setting up multiple chassis, you can link up to five of them together for larger setups. The System ID Display on the chassis will show you important information, so keep an eye on it. When using the Wireless Manager software, you can configure, monitor, and save device settings as projects. To keep your system in good shape, make sure to use the recommended charging docks (ATW - CHG3/ATW - CHG3a and ATW - CHG3N/ATW - CHG3Na) for charging. The body - pack transmitter has a water - and sweat - resistant connector, but try to avoid exposing it to excessive moisture. Also, use the auto - lock function to prevent any accidental operations. And don't forget to check the RF signal level and battery level regularly to ensure smooth operation.
