Title: Portable 48 volt phantom power
Post by: thomasdrv on January 15, 2016, 04:15:05 AM
Does anyone know which phantom Power 48 volt I need to drive my Bruel & Kjær 4037 ?
It would be nice if the phantom Power is small :)

What will you be using as a recorder?  Some have on-board P48, and, if yours doesn't, you still need to take the recorder's inputs into account.  I have no personal experience, but the Denecke PS-2 seems to be a popular choice.  It has XLR outputs, but there is a 3.5 mm mod.  You should also consider some of the small pre-amps, such as the Aerco MP-2, a little or tinybox (if you can find one), or something similar...

I second the Aerco. There's also the Audioroot Femto that looks small. The Denecke PS-2 is cheaper, but I think the battery life is shorter. I think you have to plug in an external battery pack for extended recording.

Going bigger, there are the Sound Devices products, such as the MixPre-D or 302. You could also hunt around for the older MixPre, MP2 or the Shure FP24 (essentially a rebranded SD product). They have more options for and better metering than the Aerco.

You might consider our 2Phant.

Two channels. Up to 10 mA per channel.

Two 9V batteries allow hot-swapping - no shutdown required to swap batteries.

Very efficient - lasts a really long time before batteries go dead.

Len, is the output on the 2phant balanced or unbalanced?
