The ATW-T1407 from Audio-Technica is a System 20 PRO microphone desk stand transmitter engineered for professional conferencing and installed sound applications. It features a 3-pin XLR-F gooseneck microphone connector that is compatible with quick-mount gooseneck microphones (sold separately), making it a flexible solution for boardrooms, meeting spaces, educational institutions, and corporate environments.

Designed for reliable, all-day performance, the transmitter is powered by long-lasting internal lithium-ion batteries. It includes selectable mute operation modes, allowing users to choose between toggle, touch-to-talk, or touch-to-mute functionality depending on the application requirement. Two LED display options are available, including standard mode and conference mode, providing clear visual status indication during operation.

The unit is equipped with a USB Type-C™ connector for charging, and it can continue to operate while charging, ensuring uninterrupted use during extended sessions.

Operating within the 2,402 to 2,480 MHz frequency range, the ATW-T1407 delivers 24-bit/48 kHz digital audio in both Standard and HD modes. The system provides a wide dynamic range of 120 dB (A-weighted, typical) with total harmonic distortion of less than 0.05% under typical conditions. Standard mode supports up to 10 simultaneous channels with a latency of 2.8 ms, while HD mode supports up to 20 simultaneous channels with a latency of 6.7 ms, depending on the region and environment. The system frequency response ranges from 20 Hz to 20,000 Hz, varying according to the connected microphone. For secure transmission, AES 128-bit encryption is incorporated, ensuring protected and interference-resistant wireless communication in professional settings.
