The Audio-Technica ATW-T1407 System 20 Pro Desk Stand Transmitter is a professional desk stand transmitter equipped with an internal lithium-ion battery.
The Audio-Technica ATW-T1407 System 20 Pro Desk Stand Transmitter serves as a dedicated wireless base for professional audio environments. This transmitter integrates into the System 20 PRO ecosystem to provide a stable platform for gooseneck microphones while ensuring clear signal transmission.
The ATW-T1407 features a 3-pin XLR-F gooseneck microphone connector. This interface supports quick-mount gooseneck microphones, which are sold separately. The secure connection point ensures a reliable audio path for conferencing, lectures, and boardroom applications.
This desk stand transmitter provides users with precise control over the audio signal. The selectable mute operation allows for three different configurations: toggle, touch-to-talk, or touch-to-mute. This flexibility ensures the transmitter meets the specific requirements of different presentation styles or meeting protocols. For visual monitoring, the unit includes an OLED display and two LED options, offering both standard and conference modes to signal the status of the device.
Designed for continuous use, the Audio-Technica ATW-T1407 contains a long-lasting internal lithium-ion battery. This power source supports all-day transmitter operation. The device includes a USB Type-C connector for charging. Users can continue to operate the transmitter while it is charging, which prevents downtime during long sessions.
