AM8060 JP6 Multi-Mode VCF

This module is a clone of the Roland Jupiter 6 voltage controlled filter which comprises two 2-pole OTA filters in series, and was launched in 1983. Each 2-pole filter can be switched into either Low Pass or High Pass modes providing three VCF modes all with variable resonance:

24dB Low Pass Filter
24dB High Pass Filter
12dB Band Pass Filter
The AM8060 module uses the original Roland IR3109 OTA chip as the core of the filter. I have salvaged two of these chips from an old Boss PH-2 Super Phaser pedal. This Phaser is really quite useless and the PH-2 can be bought for 30 to 40 UK pounds. It provides not only 2x IR3109 but a M5218 low noise Dual Op Amp, 5x IR9022 Dual low power Op Amps, a 4053 analog switch and NE570. The original filter in the Jupiter 6 (and MKS80 REV04) use two IR3109 chips, one as the filter cores and the other to control RESONANCE level as a dual VCA.
