Audio-Technica ATW-CHG3N Networked Two-Bay Smart Charging Dock

Product Overview

The Audio-Technica ATW-CHG3N networked two-bay smart charging dock is designed for AV integrators standardizing wireless microphone fleets across multi-room facilities. Built for the 3000 Series (4th Generation) wireless system, this networked microphone charging station charges NiMH batteries inside the transmitters and reports charging status over a standard Ethernet connection. It is a practical choice for teams seeking a rack-room-friendly two-bay transmitter charger with remote monitoring. The unit pairs reliable maintenance charging with built-in safety detection for consistent, hands-off operation.

Product Description

The ATW-CHG3N charges NiMH batteries within the transmitters themselves, eliminating the need to remove cells between sessions. The dock accommodates ATW-T220a handheld transmitters and ATW-T210a UniPak transmitters in any combination across its two bays, making it adaptable to mixed wireless inventories. A built-in safety feature continuously monitors cell voltage and automatically shuts the unit off if a problem is detected, and it will also disable charging if alkaline (non-rechargeable) or damaged batteries are installed.

Once batteries reach full charge, a maintenance charging function prevents self-discharge until the transmitter is removed from the dock, so units are ready when crews arrive. Up to five docks can be linked and powered by a single power supply (sold separately), reducing cabling and outlet demand in equipment racks. Because the dock connects to a network via standard Ethernet, charging status for all linked transmitters can be monitored centrally, which suits facilities running scheduled events across boardrooms and houses of worship. Integrators specifying full 3000 Series deployments can review compatible wireless components at Creation Networks. The result is a streamlined charging workflow that keeps wireless microphone systems dependable shift after shift.

Key Features

Frequently Asked Questions

Which transmitters does the ATW-CHG3N charge?

The dock charges ATW-T220a handheld transmitters and ATW-T210a UniPak transmitters from the 3000 Series (4th Generation) wireless system, in any combination across its two bays.

Does it charge the batteries inside the transmitter?

Yes. NiMH batteries are charged while they remain housed within the transmitter, so cells do not need to be removed between sessions. NiMH batteries are not included.

Can I link multiple docks together?

Up to five docks can be linked and powered by a single power supply (sold separately), which reduces cabling and outlet requirements in equipment racks.

How does the dock integrate into a networked AV system?

The ATW-CHG3N connects to a network via standard Ethernet cable, allowing the charging status of all transmitters in linked docks to be monitored centrally, which is useful for facilities managing wireless gear across multiple rooms.

What happens if a non-rechargeable battery is installed?

A built-in safety feature monitors cell voltage and automatically shuts the unit off if alkaline or damaged batteries are detected, helping protect both the dock and the transmitter.
