Audio-Technica ATW-1421/L System 20 PRO Wireless Lavalier System

The ATW-1421/L is the dual-channel lavalier configuration of Audio-Technica's System 20 PRO, a 2.4 GHz digital wireless platform that sidesteps the crowded UHF TV bands entirely. It pairs one ATW-R1440 four-channel receiver with two ATW-T1401 body-pack transmitters and two MT830cW omnidirectional lavalier microphones, so two presenters or performers run on one half-rack receiver. Automatic channel selection and 24-bit/48 kHz audio keep setup quick and the sound clean.

Each body-pack uses a locking cW-style connector to hold the lavalier securely, and OLED screens on the transmitters and receiver show channel and status at a glance. The system operates across the 2.402 to 2.480 GHz ISM band with up to 10 channels in standard mode or 20 in HD mode, over a line-of-sight range of about 60 m (200 ft). Rack-mounting hardware for the receiver ships in the box.
