How do I connect AKG B18 Phantom Power Supply to feed 48V?

There is space only for 2 9v that makes it 18v but there is also note
on another connector that to use converter for 48V operation.

but how this is done? I plan to use 5x 9v batteries with this...

need just quickly 48V phantom for Shure FP11 micpre

is one solution but not really this time. is it possible to go round of this
converter and use 5x9v batteries instead ?

looks like this...
http://www.akg.com/products/powersla...uage,EN.h tml

but should I just ignore this adapter and place (-) of my 5x9v battery chain
to (-) of this Phantom PSU and (+) of my battery chain to (+) of this
Phantom PSU

Should perhaps work that way? Or what information goes there inbetween those
+/- connectors?

The B 18 by itself isn't capable of 48 Volt phantom powering. There is
a special, optional accessory for the B 18 which was (and may still be)
available from AKG; it has the size and shape of a 9-Volt battery, and
it contains a DC/DC converter. You install it in one of the pockets,
with a 9-Volt battery in the other pocket, to produce 48 Volts.

I have one here but have not tested it. I will do so on the weekend if
that would help you.

Don't know about the original poster David, but I would be interested in
any test reults you produce. I have run an AKG 451, an SE300B (Blueline)
and years ago now a 414 from the AKG battery box. I have et to try my
Schoeps CMC6...

AKG mics of that period, with the exception of the C414-P48 would work
just fine from 9V on up. That's why they built that 18V power box.

I don't know about the Schoeps. If that's one of the models with a
compartment for a battery in the mic body, then it'll probalby work OK
on less than 48V. Otherwise, probably not.

The Schoeps CMC6 works with 12 - 48V phantom. Did Schoeps make
any mics with battery compartments? You might be thinking of the
old Neumann U87's.

It's one of the 9-52v preamps. The caveat is that as the phantom volts go
down the cureent consumption goes up. Schoeps' specs say current draw at
12v is 10mA, as against 5mA at 48v.

Actually I was thinking of Sennheiser when I saw Schoeps. You know,
all those Italian names that start with S look the same.

Schoeps, Sennheiser, Sanken, Samson, Shure...

all those sound little same but is any of these italian

The CMC 6 accepts standard 48 Volt phantom powering or standard 12 Volt
phantom powering. But that isn't the same as accepting any old voltage
in between. Or OK, it will--but the amplifier has two discrete "modes"
of powering, with logic that chooses between them based on the supply
voltage as sensed within the amplifier. The mode, in turn, determines
the current consumption of the circuit as a whole.

If you try to power the microphone with something that's well below the
tolerance limit for 48 Volt phantom powering--say, 30-something Volts as
in certain wall-wart-driven portable preamps--a supply designed only to
deliver 1 or 2 mA per microphone may suddenly be called upon to deliver
five times that much current on a continuous basis.

That won't work for long if at all. It would really be better to have
a solid 12 Volt phantom supply than an iffy pseudo-48 Volt supply.
