The Sennheiser CHG 70N is a network-enabled charger with two bays, capable of simultaneously charging up to two EW-DX SKM handheld and/or EW-DX SK bodypack transmitters with their respective BA 70 batteries inside. It can also recharge standalone BA 70 batteries. The Charger features an RJ45 network socket that supports the Media Control Protocol to provide remote control and status monitoring via the Sennheiser Control Cockpit software or a third-party application.

The CHG 70N operates on Power over Ethernet (PoE IEEE 802.3af Class 0) or on 12 VDC input voltage supplied from the EW-D POWER SUPPLY (available separately). Up to five chargers can be daisy-chained with only one PoE network connection or power supply needed—allowing you to recharge up to ten battery packs or transmitters at the same time.

Charging time for a full charge is approximately 3.5 hours (2 hours for 80% charge). A colored LED at each charging bay indicates charge status.
