The Sennheiser CHG 70N-C AC charger is a dual-slot device designed for efficient and safe charging of transmitters from the EW-DX series. Supplied with the NT 12-35 CS power supply, it forms a complete solution that performs equally well on tour and in fixed installations. Thanks to its stackable design, multiple chargers can be linked together to create extensive charging stations for larger systems, including Spectera.

Product Features

The Sennheiser CHG 70N-C is a stackable 2-slot AC charger designed for EW-DX transmitters. The device is equipped with the NT 12-35 CS power supply, which ensures stable voltage and fast charging of BA 70 batteries. The compact housing and the ability to link multiple modules make this charger ideal for professional audio applications where reliability and flexibility are paramount.

Flexible Expansion and Mains Power

Stackability is a key advantage of the CHG 70N-C charger. Using connectors, several units can be placed side-by-side to create a unified charging station for up to a dozen transmitters. This is particularly useful in Spectera systems where many channels operate simultaneously. Mains power eliminates the need for external transformers – simply plug the power cable into a standard outlet. The charger automatically recognizes BA 70 batteries and optimizes the charging process, protecting the cells from overcharging and extending their lifespan.
