Hello,
where can I find the schematic ? there is nothing to see and I have to rebuild A N1209-8A for our Cinema.

Thank you very much.

I'm pretty sure the 1209 is the same as a 1201 except it has parallel 1/4 inch inputs instead of push button terminals.

EDIT: actually, they are different, and thanks to Earl K this thread explains the differences nicely: Altec crossover

The schematic for the 1209-8A network above has an error in the HF lpad section. I?ve redrawn it after noticing that the original drawing shorts out the HF lpad.

Thanks for spotting the error!
Here's the corrected version

It?s great you updated the original schematic, my correction was a bit crude. What app did you use to make this schematic?? Thanks Mike for doing the work on these.

LoL, I use MS Power Point. No problem, I enjoy adding to the knowledge base.
