+ | **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. | 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.
