DESCRIPTION
The ATW-T1406 is a wireless boundary microphone transmitter for the System 20 PRO platform, combining an integrated cardioid electret-condenser capsule with AES-128-encrypted 2.4 GHz digital transmission in a sleek, cable-free tabletop enclosure. It delivers conference-quality audio to boardrooms and worship spaces without a single visible cable or the complexity of UHF licensing.
The built-in lithium-ion battery provides up to 12 hours of operation and recharges in just 3 hours 10 minutes via USB-C âÃÂàeven during use âÃÂàwhile a customisable mute button supports toggle, touch-to-talk, or touch-to-mute operation to suit different meeting protocols. An OLED screen displays channel, level, and battery status, and the unit's boundary design maximises pick-up of voices seated around a table.
