The Sennheiser GA 6042 BA is a battery pack adapter for the EK 6042 wireless receiver. It mounts on the GA 6042 BA backpanel adapter (available separately), allowing you to power the receiver with two BA 61 rechargeable battery packs (available separately) when using the receiver without a camera.

The GA 6042 BA can also be used for hot swapping batteries while a shoot is in progress. The L 60 charger (available separately) is required for recharging the battery packs.
