Audio-Technica ATW-T1402 System 20 PRO Handheld Transmitter

The ATW-T1402 is the handheld transmitter for System 20 PRO: a wireless vocal or roving audience microphone on a 2.4 GHz digital link with no frequency coordination to manage. It is the channel that gets handed around a room, which is why a licence-free band and a fixed pairing to the receiver matter more here than tuning range.

It operates on 2,402 to 2,480 MHz with AES128 encryption, passing 20 to 20,000 Hz audio at 24-bit/48 kHz with 2.8ms of latency and < 0.05%, typical of distortion. It pairs with the ATW-R1440 receiver, and a system supports 10 channels.
