Diaphragm Baby Bottle Condenser Circuit Board with Plug

1. Polarization voltage board can be applied to other transistor front circuit boards, suitable for DIY use by friends with strong manual ability.
2. Single 60V output, +-60V dual output, dual +60V dual input, +60V and +120V dual output, can be according to the polarization voltage of the diaphragm, single output is suitable for single-layer membrane microphones, dual output Suitable for double membrane microphone head
3. It is recommended to use +60V and +120V dual output version. If you feel that the sound is not loud enough and the sensitivity is not high enough with 60V, you can switch 120, and you can connect a switch.
