M-613 3ch stereo slider mixer expansion module for Eurorack / Doepfer A100 system.
Extra three inputs for M-610 or M-611 stereo slider mixers (9 inputs total with M-610 or 6 inputs with M-611).
Connection to M-610/611 mixer requires simple soldering of three wires (three soldering points).
You´ll get mixer with new-style pan knobs as standard (blue with silver panels and gray with black panel), see pictures of M-610 mixer.
If you already have an mixer or expansion with old-style pan knobs (black with white pointer) and you want to keep same knobs on all mixers kindly let me know.
I can send you either new mixer with old-style black/white knobs or set of new-style knobs in bag for mixer you already have.
