I've looked everywhere twice now so I guess I will risk asking a stupid question: what is the input sensitivity of the ST35 rev D ?
I have to make some design decisions for the line preamp board I am building to integrate into my ST35.
I've already decided to add capability to split the preamp section from the ST35 section via RCAs in back and use DPST reed relays for switching inputs. It is rapidly approaching chassis building time.
