SP-SPSB-10 – Micro-mini 12v microphone power supply

Brand: Sound Professionals
(2 customer reviews)


Micro-mini microphone power supply with mini 12vdc battery and 24 inch hardwired output cable

This battery module is recommended when you need to use our small microphones in high SPL situations. The case of the mini battery module is made of lightweight black ABS plastic.

This product will power your microphones with 12 volts of bias power (sometimes called “plug in power”). Most small Electret Condenser microphones will enjoy improved high SPL performance with this higher power, since most portable recorders only provide about volts plug in power at the mic input.


  • Dimensions: .8″ x 1.38″ x 1.97″
  • Small, lightweight case
  • Power module has 30-50 hour battery life, depending on microphones used
  • 24″ output cable with 3.5mm stereo mini plug
  • Uses small A23 type 12v battery (one is supplied with product)
Weight 0.3 lbs

    So far, I am impressed. I had a chance to try out the SP power supply last weekend with my old Oade micro mics. It powered the mics without fail. I recorded an outdoor show, however, the wind obscured the sound so much; it is hard to discern the actual quality of the recording. I have another opportunity to try this rig again next week. I will update my previous Amazon review to reflect what I learn from this next recording. On the unit itself, it’s beautifully made and so much smaller and lighter than the original power supply that I bought with the mics, some 20 odd years ago.

    Works extremely well in powering small microphones. Very solid build quality, and very compact. Ideal for low profile situations.
