The Sennheiser GA 3041-BC is a slot-in housing kit, which allows the EK 3041 receiver to work in standalone mode without a camera—as in a bag or with a mixing console.

The kit consists of the GA 3041-C slot-in housing, the GA 3041-B battery adapter, and the B 50-2 battery case for two AA batteries (available separately).

The slot-in housing features a balanced XLR audio output and a 4-pin DC input connector, giving you the option to power the receiver with a battery distribution system.

The GA 3041-B battery adapter accepts B 50-2, B 250-2, BA 50-2, and BA 250-2 battery packs. It also features a clip to hold it securely in place on the housing.
