following some ideas i had some time ago, and remembering the great Mikkel (mcs) relay switching board, i tought that maybe for my upcoming api clone i could use a digital stepped attenuator system..
let me explain:
a simple rotary encoder, a 2 or 3 digit 7 segment led display (to show the db value) and mcs's relay switching board..
how to connect all this?
well.. i don't know :green:
DaArry told me something like: "maybe we could use the mios here"..
see the mios system here: http://www.ucapps.de
found also some more documents about this:

why all this?
well.. recallable settings (even via midi), no need to source hard to find rev log pots, probably cheaper then the pots if you do some mic pre channels in one box, no audio loss cause good relays and 1% metal resistors are better then most of the pots.. also..this "interface" could be used in any other mic pre... the only thing to change will be the resistors value, to match the mic pre original attenuator design.
So, what do you think?
who could help me here to design and troubleshoot this project?
this could be an interesting "new era" add on to any project and surely a future GroupDIY project age somehwere :wink:
