Here is a video of my problem. The compressor reacts weird:

I can see you that your return from your board is going to the wrong 47k pad. It should be returning back to the one that is closer to the sidechain section. Are you also getting the proper VDC to your SC board?

Thanks!

Thank you!
I think the pads from the resistors are bridged.. Either was I tried it both ways as I found two different wiring guides but none of them works. voltages are spot on.

If the schematics from the old and new GSSL boards are mostly the same then that is correct regarding the 47k. The thing that makes troubleshooting as a third party difficult is that I don't know how many people are familiar with this particular SC board you are using. If the circuit is indeed without problems then there has to be a build error involved somewhere provided you do indeed have a working GSSL without the mod board. You may have to contact the designer directly.

In the meantime, since you aren't using a thrust type circuit and just putting a HPF on the side chain, you should be able to do this passively as that is how it is done on the newer GSSL boards. You would have to look at the current schematic to see where the capacitor for the HPF is connected and just insert a switch with the caps you want to use. I believe you can passively add the external sidechain source as well with the appropriate resistors/caps in line.

Thanks!

i contacted steffen but waiting for reply. although like you said i am not sure if the board is the problem. I am replacing it with a super sidechain board now to see if the problem remains...

thank you

Hey! Don't know if you solved it already, but i had absolutely same problem. Same acting of meter, absolutely same.

In my case problem was in turbo mode board.  Just a bad connection, i started moving cables and found that problem dissapears sometimes, so i resoldered these connections and made new cables to connect and problem was gone.
Sometimes i think it's better to solder in those cables when you checked and all working fine. Had this issue in two gssl with turbo mode.

oh, thanks for the explanation!
i replaced the board by a super SC board and everything turned out to work fine. no idea what the problem was in the end..  :D
