Audio-Technica ATW-1423/L System 20 PRO Wireless Combo System

The ATW-1423/L is a two-channel bundle from Audio-Technica's System 20 PRO, the 2.4 GHz digital wireless platform that sidesteps UHF TV congestion and frequency coordination. It pairs the ATW-R1440 four-channel receiver with two transmitters: an ATW-T1402 handheld and an ATW-T1401 body-pack wearing an MT830cW lavalier, so one system covers a presenter at the podium and a second on a lapel.

System 20 PRO runs 24-bit/48 kHz audio with AES128 encryption, and OLED screens on the receiver and transmitters give clear readouts for setup and monitoring. The cW-style connector on the body-pack locks the lavalier securely. The kit ships with the ATW-R1440 receiver, both transmitters, the MT830cW lavalier, an AT8456a mic holder with 3/8-inch to 5/8-inch thread adapter, and rack-mounting hardware.
