Audio-Technica ATW-CHG3A Two-Bay Charging Station

Keep wireless transmitters and in-ear monitors charged, safe, and ready with the Audio-Technica ATW-CHG3A two-bay charging station. Designed for 3000 Series transmitters, 3000 Series IEM receivers, and System 20 PRO transmitters, this battery charger charges NiMH cells while they remain housed in the device, streamlining fleet management for AV teams, security integrators, and broadcast engineers. The unit runs from a 12V DC input and provides a regulated 3.6V DC output per bay, with automatic shutoff if alkaline or damaged batteries are detected and an onboard maintenance charging mode to retain full capacity. Link up to five chargers to a single power supply for scalable deployments across monitoring stations, surveillance control rooms, and event carts. User-friendly LED indicators, automatic power-off/on of transmitters in the dock, and a compact footprint reduce setup time and rack space. Ideal for security, surveillance, live sound, and corporate AV applications — add the ATW-CHG3A to your workflow to improve uptime and simplify battery management.

• Keeps transmitters and IEM receivers ready: charges NiMH cells while batteries remain in 3000 Series or System 20 PRO units for fast, hassle-free turnover
• Protects battery health and equipment: automatic shutoff for alkaline or damaged cells plus maintenance charging to preserve capacity
• Scalable power for installations: up to five ATW-CHG3A stations can be linked to a single supply for simplified rack or cart deployments
• Simplifies operations on the road or in the field: transmitters power off when docked and power on when removed, with LED status indicators for quick checks
• Compact, professional design: small footprint (7.28" W x 3.90" D x 2.70" H) and 12V DC input make it ideal for AV carts, studios, and security control rooms
• Built for reliability: robust safety features and a 2-year limited warranty reduce downtime for surveillance, monitoring, and live-event systems
