Neumann and Siemens summing cards

Not sure if this is the right place for it, but was curious if the pin outs for the Neumann V475-2C and Siemens MV V2275 were the same? I have a summing mixer with the Neumann, but wanted to know if I could just drop this card in its place.

Thanks in advance,

I've googled for the schematics without success. Has anyone run into one of these before? I believe it's just the V275 in stereo.

Finally getting back around to looking into this and would love some assistance.
Just sent a request to Vintage King. Seems like the connections would be similar. Still haven't found any schematics.

Yea these ones out here wouldn't have it, however I have all of that old German console stuff.
So I'll give you the skinny with my thickie:

[U: Dynamics, talback modules, drivers for meters, etc.]
[V: Any sort of amp]
[W: EQ's, faders, pan, other misc stuff (ms-matrix, oscillator, etc.)]
[All the rest]
3-digit numbers: 1st digit indicates manufacturer.
2xx Siemens
3xx TAB
4xx Neumann
6xx Telefunken (later ANT)
7xx Telefunken/AEG
9xx Lawo (later used by ANT, too)
11xx BFE
20xx Curt Hensmann, later Adis

Here is my schematics for this card by both manufacturers. There are dififferent revisions depending on op amps, or DOA.

Thanks for the reply. What I have I believe is the stereo version of the V275 which is mono. So the 2275 should be handled similarly to the stereo V475 wiring wise?
