12 Channel mixer panel


i’m trying to rebuild a 12 channel mixer panel with the modules K2662, K2663, K2664, K2665…
I wonder if anyone has a schematic of this modules or a user manual…
Anything will do :wink:
I know its obsolete…

Note: the text on the print is P266x

Thanks in Advance,


Hello Ronny,

Did you ever get a chance to make these ? If so could you give me a copy as I’ve got a schematic and component layout but can’t be arsed to design It ! (K2663)
