"Getting Ready for SuperBooth 22
We are hard at work developing new modules for launch at the best synth show of the year - Superbooth 22. We will be announcing the red faced AM8101 filter [posted here], a replica of the low pass filter in the Roland SH-101, as well as the AM8102 SH-2 style filter [below].
The AM8109 and AM8060 Jupiter filters are being relaunched - 10 years after they were introduced, with Special Edition and slim 10HP versions. AMSynths will also be announcing SH-101, Jupiter 6 and 8 VCO's to pair with these filters alongside the current Jupiter 4 VCO and VCF."
This module is faithful replica of the filter from the legendary Roland SH-2 that was released in 1979. The AM81012 is a fantastic sounding 4-pole low pass filter with that unmistakable Roland filter sound in a narrow skiff friendly, Eurorack module.
The module use an Alfa Rpar AS622 chips in the filter core (BA662 clones) and high quality polpropylene filter capacitors. The design includes buffering Op Amps to interface to Eurorack modular levels. The filter does not have Q compensation but the signal level does not decrease dramatically with higher Q settings. The resonance is smooth and controllable into self-oscillation, and the filter will oscillate from 20Hz to 20kHz.
There are slide potentiometers (with LED's) for adjusting the Frequency Cutoff, and the frequency modulation from Keyboard, LFO and Envelope CV signals, There are rotary potentiometers for adjusting the mix between two audio inputs and Resonance. There is a small slide switch to select whether the envelope CV input is Normal or Inverted.
The AM8102 is hand built with high quality components, including Wima polypropylene capacitors, Alpha potentiometers, and TR808 style control knobs.
There are six 3.5 mm jack sockets on the front panel:
2x audio inputs
3x frequency CV inputs
1x audio output
The module comes with a set of M3 mounting screws and washers, and a standard Doepfer power cable.
