The Audio-Technica ATW-T1407 is a desktop digital wireless transmitter designed for use with gooseneck XLR conferencing microphones and compatible with a System 20 PRO receiver (microphone and receiver both available separately). The unit delivers high-quality audio transmission at 24-bit / 48 kHz resolution and features a low-profile form factor well suited to meetings and educational applications. The female XLR 3-pin connector supplies 24V phantom power, allowing the transmitter to work with a wide variety of gooseneck microphones. A customizable mute button lets you choose between toggle, touch-to-talk, and touch-to-mute modes, depending on your preferences, while an OLED screen on the bottom shows you channel, level, and battery information.
