+**Warning:** This is not a suitable project for absolute beginners. The soldering isn't very difficult, but you will need either an AOUT_NG (SMT soldering required), an AOUT module (which needs to be expanded with the bipolar option) or two (!) AOUT_LC modules, or another type of CV source to control this module, in addition to the actual synth (SID/FM) you want to use it with. So a bit of soldering experience and knowledge about the MidiBox platform is definitely recommended.

 This PCB contains two of the famous SSM2044 24dB low pass filters with the necessary circuitry, additional LM13700 based Q linearization circuit and a tiny Omron micro relay for a software controlled (via gate out pins) bypass function. The layout is optimized for use with the [[aout_ng|AOUT_NG]] module, requiring the addition of a bipolar option when used with regular V/Oct sources like the original AOUT module.

+nILS did a Reichelt [[https://secure.reichelt.de/?;ACTION=20;LA=5010;AWKID=137885;PROVID=2084|Reichelt public shopping cart]], thanks for that :)
