SUM 2 (V1 2020) no Send output

Hello,

(Firstly thank you for all your lovely designs, I love my ST Modular modules).

I finished building this Sum 2 last night and everything seems to work - except for the Sends.

Neither Send A or B output any sound no matter what I have tried.

(Please pardon these photos are not great).

Where should I begin to debug this?

Thanks again

Hey Dan,


as soon as you solder the SMD jumpers S1 -S5 to POST or PRE, I´m sure your send channels will work :-) The send channels can be set to be active either pre or post AFL per channel via a solder bridge. ‚Pre‘ means you can still hear the send/return way when it is in AFL mode (thus the channels signal is actually not audible in the main mix), ‚post‘ means send/return will only work when the channels signal is routed to the main mix. Best, Stefan
