Overview
Product description from Audio-Technica
The ATW-CHG3a is a two-bay charging station for use with 3000 Series transmitters, 3000 Series IEM receiver, and System 20 PRO transmitters. The station charges NiMH batteries (not included) while they are housed within a transmitter or receiver. It will automatically shut off if alkaline or damaged batteries are detected. Once fully charged, a maintenance charging function ensures that batteries retain their full power for as long as the transmitter remains in the charging station.
The ATW-CHG3a is equipped with power and charging status indicator LEDs for easy monitoring.
Using the AT8687 link kit and AD-SA1230XA AC adapter, up to five ATW-CHG3a charging stations can be linked and powered by a single power supply. The AT8687 and AD-SA1230XA may be purchased separately or bundled with an ATW-CHG3 (see bundles separately).
