AM8121 VCF PCB
Product Code: AM8121PCB
Product Description
NEW SKIFF FRIENDLY VERSION WILL BE AVAILABLE IN NOVEMBER

This is the PCB for the AM8121 Voltage Controlled Filter. This PCB can be used to build a FracRac (15v power and MOTM style 4-pin power connector) or EuroRack (10-pin 12V Doepfer Bus power connector).
 
The AM8121 is a replication of the Low Pass Filter from the legendary Roland 100M. This is a 4-pole OTA design that Roland first used in the Roland 700 (with CA3080's) and then the 100M (with BA662's). This is a warm sounding filter with smooth frequency control and a resonance that gradually increases up to full self oscillation. There is a 4-mode High Pass Filter which provide a bypass setting and then 3 levels of high pass filtering from a one pole design.

Project Notes These explain how to build the module and the parts needed.
