AM8102

SH02 LOW PASS FILTER

Description 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 Pro One style rotary 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. The module comes with green LED's fitted. These can be swapped with the included yellow LEDs by the customer, if you want a different colour or slighly lower brightness.
