Quad Mixer-Attenuverter 8HP Mixer/Attenuverter with optional offset function.
This design is based on the work by Kassutronics: https://kassu2000.blogspot.com/2018/04/precision-attenuverter-mixer.html I will not share my PCB design of this module per request by Caspar from Kassutronics. Only the schematic is available.
