I think I figured it out:

Set Board jumper: bridged = decreased volume due to R3 being on / unbridged = increased volume

Filter jumper: bridged = 6581 / unbridged = 8580

according to x1541 who said: “Ja er ändert die Emulation auf 6581 wenn er geschlossen ist.”

Hope Swinkels can confirm it.

You’re right. R3 jumper also changes output biasing. This was needed because older C64 boards has bit different output stage and I decided to simplify desing by adding jumper instead of a more complex but universal solution.

There was special firmware version specially designed for MIDIBox with extended filter range but this feature is not enabled in standard release.

Anyone know where I can find that firmware?
