AA battery eliminator / buck converter for Sennheiser G2, G3, G4, EK100, EK300,EK2000
(Sennheiser DC2 replacement part)

This product is particularly interesting for location sound mixers or audio engineers who use Sennheiser radio links (e.g. EK100, EK, 300, G2, G3, G4, EW 100 series), who normally need two AA batteries and have no external DC input.

The converter is a USB power adapter and a battery eliminator that supplies up to 2 radio receivers simultaneously with a standard USB power bank.

Simply plug the battery adapter kit into the battery compartment of each receiver / transmitter and connect the controller to your rechargeable 5-volt USB power bank. With a single action, you can switch all your radio links on and off at the same time.
