TBP12 Voltage breakout

Recommended Posts

Hi from Germany,


I am a part-time audio engineer in Germany. During these strange times I developed an idea. I assembled a voltage breakout with a TA4F plug to provide the 5VDC  for some reasons. I checked the voltage between PIN1 and PIN2 with my multimeter and it was showing me the expected value. But as I connected it to a load it seemed to me, that the TBP12 can't provide the electric current.

Does anyone know, if there is a limitation for the electric current or if the power supply function is only working reliable, when a lavalier or headset is connected to the beltpack?


Thanks in advance and kind regards

The output is almost certainly current limited as the mic capsules only need a couple of milliamps.
