Infoseite // Bastel Simple solution for 48V phantom power from batteries?



Frage von fotoralf:


Wanted is a possibility, two microphones with 48V phantom power regardless of mains s.einen NV-GS400 adapter without the price of feeding the modules of the microphones or exceeds the whole solution is difficult and cumbersome.

Should really with 5 x 9V block (really are the full 48 V range is required or synonymous 24, 12, oderwasauchimmer ...), a few resistors, a transformer per Microphone jacks and the right, or?

Soldering and technical skills are available.

That's already done ... a 9V Battery extends normally ...
for example here:

of her price is certainly the same as if you build it yourself ...

That went fast. :-)

Only because I would have already made two, because according to diagram in the service document (via download of the AKG website, all respect!), The two microphones connected to a mono mix. Moreover (which are AKG Microphones Series "L"?) Provides a true phantom of the circuit since actually different.

Stereo operation with 9V Battery, and a few dB gain we can get back synonymous small. :-)

If ordered tomorrow. Times I'm curious to see what's inside.

For the price you get so do not even housing, connectors and switches for the self. Because it is really not even soldering and holes to hone.

Antwort von robbie:

Oh, sorry, yes, I did the part is not accurate, was just as small a source of inspiration thought ...

The part of music production is then for your purposes, probably more suitable.

Yes, for DIY - equipment of this size it is usually the case, including housing, components and board between 50 and 70 eu reckon. What the housing of the most expensive part is ..
