Sennheiser B 30 AA holder

The Sennheiser B 30 is a battery holder for two AA (mignon) cells that fits the SK AVX bodypack transmitter, the SL Bodypack DW of the SpeechLine Digital Wireless series and the evolution wireless D1 SK. With it the transmitter runs on AA cells that are available practically anywhere. It is a handy backup for long events and a spare part for a lost or damaged holder, weighing only 21 g.

A transmitter on AA batteries

The B 30 battery holder goes into the transmitter in place of the rechargeable battery and powers it from two AA cells. When the rechargeable battery runs flat, just reach for batteries.
