12 volts on Schoeps microphones?

I can't readily find out what circuitry is in the Sound Professionals module, but it almost certainly doesn't provide standard 12-Volt phantom powering for professional condenser microphones, or the company would surely say so. It seems instead to be made for unbalanced electret microphones only.

Another clue is that the type of battery that they sell for it wouldn't last very long powering a professional condenser microphone. So I really don't think so.

If this module did provide standard 12-Volt phantom powering, that would work with many types of Schoeps microphones--all "Colette-series" microphones that use CMC 1, CMC 3 or CMC 6 amplifiers, or the CCM series of compact (non-modular) microphones--but not others that they've made in the past, such as the CMC 4 and 5.

--best regards

Why don't you tell us which mics you're trying to run and we'll tell you the best way to power them? ;)

sound professionals site confuses me... i cant seem to get to their battery box page. i do beleive they offer a 3-wire battery box with power on a separate lead, which would work to power schoeps CMR preamps when used with a 9V battery. if not, they are not difficult to build. just a 9V battery, capacitor, and resistor in the circuit

nevermind the above if youre set on CCM series - they require true phantom power. The easiest way to do this is a recorder which has it on its inputs, of which there are many small-ish options to fit all sorts of budgets, from a Tascam DR40 to a sonosax SX-M2D2 with all kinds in between

I have a 4-track Tascam DR-2d recorder to run mics + IEM so I don't want to run a 2-track recorder.

My plan B is a CMC-1/MK41 combo, does it make any difference?

cmc1 is a little more efficient on power but still requires phantom.

there are also stand alone phantom power supplies out there

sounds like you want to do  >:D , if you havent bought the mics yet, the smallest solutions are
CMR w/battery box
nbobs with baby nbox
nbobs with naiant IPA

CMC 1 + capsule approach can be clearly recommended over the CCM. It's less expensive, draws about half as much current for equal or better performance, rejects RFI better, and most of all it's modular--if you decide later on that you want to try a different microphone pattern, you only need to get new capsules, not complete microphones.

Yes... It's the CMC 1 L
Mics: DPA 4060 - OKM II - SP-CMC-4U (AT853)

Power: A3 - SP-SPSB-10

IEM Receiver: Sennheiser EK 300 IEM G3 (A-Range) - Sennheiser EK 300 IEM G3 (B-Range) - Sennheiser EK 2000 IEM (Aw-Range) - Sennheiser EK 2000 IEM (Gw-Range)

Lemo version is out already. The fixed cable version is the one that was initially announced for January and that has yet to see the light of day.

From a technical perspective, the best option would be a CMC 1 L (or other variant of the CMC 1) plus capsule into a phantom power supply (or recorder). The CMC 1, like all other Schoeps CMC and CCM mics, outputs a true balanced signal, which is great at rejecting RFI.

More "stealthable" approaches would be the ones jerryfreak mentioned. Capsules, active cables and a battery-powered supply built specifically for active Schoeps mics. However, all of these have a non-balanced signal and therefore are not as immune to RFI. However, this is what most people here are running and most of the time this is not a problem.

Edit: Like DSatz already said, it doesn't really make sense to get CCMs these days. The CMC1s + capsules are the same size and more versatile.

I actually own a pair. They're nice and run on a small 6V battery for 60-80 hours. However, they're full-sized mics. And as such, they're quite different from the small CCMs you were initially looking at. They're a good choice for open taping, I guess. The signal from mic to recorder is unbalanced.
