Upgrading SAJE mixing console master with a Lawo dv972

[dasnevestheo]

Hello there !
Just got a hold on a pretty Lawo dv972 amp card and I would like to upgrade my console master section with it.
My console is a SAJE Auxy (french 80's brand, pretty cool channels but summing sucks a bit...).
Saje channels summing resistors are 22k. I was thinking of sending the passive sum of the channels into the Lawo inputs.
Question is, on the original master section, there's a  0dB opamp filter stage (IC1) pre fader, which then goes into a 12dB gain stage (IC2) : can i put my fader between bussed resistors sum and Lawo Input ? Or is a buffer needed pre fader ?
I'm attaching the summing section of my current Saje master section.

Any tips welcomed

Thanks

Hi,
Hello from France
Sorry I have only Odyssey, and ULN, but the Auxy will be not difficult.
Cheers,

Thanks, plimousse. I'll keep trying. I'd like to see my console fully working so I need schematics.
