Anyone know of the simplest way to provide phantom power (the usual 48v)
to a mic amp that currently doesn't have it?
Obviously, an external plug in supply is one way, but wondered if there
was an IC or whatever that would produce it from the mic amp's existing
PS, which is a discrete +/-15v type.

At 29e it is not worth even heating up your soldering iron:-)
Powers two mics at 12V or 48V. Highly recommended.

Iain, did you actually even read the question?

Yes. Apologies. I am currently doing a project
on a Studer desk that has phantom on only 12
of the sixteen inputs. Modifying, or making additions
to, the Studer mic modules was not an option, so
we bought 2 of the Thomann phantom supplies.
I thought you had a similar situation.

Interesting. Don't think I've ever seen a mixer with only some of the mic
amps having phantom. It's not as if it would save much cost in production.

No. It would not have saved anything.
But it was ordered like that, as a custom console, by NDR.
It has some very interestiing and useful features
such as group correlation which are not often seen.

** Get a 1W isolated, DC/DC converter module - Farnell sell them.

You need one rated at 15V input with 15-0-15V output. Simply stack
the output on top of the +15 volt input and you have 45 to 48 V DC.

I have done this several times and it works a treat.

Thanks, Phil. Knew someone would understand the question. It never
occurred to me to do it that way.
