Title: What kind of mics is it possible to power with a BS48i-2 from Neumann?
Post by: chrisv31 on July 23, 2011, 01:38:25 PM

Hi,
I've found a BS48i-2 with a very good price and I would like to know if it's possible to use it with:

-MILAB VM-44
-MBHO 603A
-Neumann KM100
-Schoeps
-DPA 4011C

Thanks in advance for your help

Any and all 48V microphones should be able to be powered by this.  You may need to make cables because they are 5 pin XLR and you will need them to break out to dual 3 pin, but it should work with pretty much any mic that requires P48

Thanks for your message :)
i have just completed the order  !

Do you know someone able to build me a Y cable : 5pin XLR(M) to (2) 3pin XLR(F) and a  5pin XLR(f) to 3.5 mini to the deck?

cheers

Maybe it's a stupid question but i've got a little doubt about the Nemann BS48i-2.
by example if I plug 2 milab vm44 on it, the output signal is  A stereo Signal or a MONO signal?

Thanks  :)

It wil be two separate signals.

Note that there are a few mics out there that needs more than 5 milliamps, most notable the Earthwork ones. Milab will be fine.

It will be stereo.  You need a cable to break out the 5 pin output to a dual 3 pin XLR.  Gunnar is right though - check the requirements for the mics you buy first just to be sure it will supply adequate power.

A few folks in the first post are no longer making cables but many are. Or scroll to the bottom and add Ted to the list.

I can make you one as well if you like.  I have all the connectors on hand anyway.

Thank you all for your messages :)

Last Question
If I plug 2xmilab vm-44 link or 2xMBHO 603a can I use a custum cable ( 3xlr to minijack) for the output signal (I have a ls10 from Olympus for the moment as ).
I'm a lost with the balanced and non-balanced signal (shame on me, I know :) )
Thanks
Chris

I believe it should work. A custom cable, 5pin xlr to minijack.

I used to use a BS48-i2 to power my B&K 4011's with great results!

Other high-current 48-Volt phantom powered microphones include models from CAD (Equitek) and some Shure KSM condensers, as well as the original AKG C 451 (not their modern-day "C 451 B" which is quite different). These would not be powered reliably by a supply that puts out "only" 5 mA/channel.

I have to put "only" in quotes because I well remember the 1970s, when typical 48-Volt phantom supplies could only put out 1 - 2 mA per channel.

--best regards
