K3 phantom power

[Bob W9RFS]

Would it be possible for the K3 to provide 48volt "Phantom" power for profesional condensor microphones?
Thanks!

[Don Wilhelm-4]

Bob,

While that would be a nice addition, I think it is not possible inside
the K3 - there is no source of 48 VDC available.

As an alternative, consider one of the small audio mixers - the
Behringer 602 (now Xenyx 802) provides 48 volt phantom power for 2
microphones and 2 additional stereo channels of mixing.  I find it quite
useful in the hamshack - although I do not use the pro mics with it, it
does have that capability and is inexpensive.

73,

Hi Bob,

We do not have this capability in the K3. Since we run off of 13.8V it
would take a redesign to accomplish that.

However, there are a number of DC to DC converters on the market. I've
used Artesyn a number of times in solar power installations. Never a
complaint, and the oldest install is just over 7 years in operation
now.  Digikey and Mouser both stock Artesyn, and there is room in the
chassis for it.  Just a thought.

Pick a DC-DC converter for the 8 to 16 Vin range, to give 48VDC out.
Get the power rating that applies to your mic.  Probably pretty low.

Bob & others,

I think the easiest way to get 48 VDC phantom power for a "real" mic is
to put a small mixing board or mic preamp between the mic and rig.  I
have a (yuck, spit) Behringer board that cost me $100 about 10 yrs ago
that provides phantom power on 4 channels plus some EQ and, of course,
mixing capabilities.  Or I can use my Mackie board to do the same.
That's how I run good mic into my rig.  If you don't want a mixer, you
can get several different mic preamps that will provide the phantom
voltage the mic needs.

I have a preamp with phantom power made by Samson I believe it was $48. I noticed that Ramsey Kits has it listed in their latest catalog.

It would probably be easier to purchase an inexpensive mixer from a company like Behringer. many of these have switchable on/off phantom power supplies. This would also give the ability to introduce other components into the "mix" as well. Some or most of theses also include a simple EQ built in as well. This may also complement the EQ included in the K3 nicely. I will add a post as to how these mesh with the K3 when mine arrives. I hope this helps. Have a great week.
