S-411 Shaper module for eurorack / Doepfer A100 system.
Compares input voltage (or ctrl input voltage, normalled to input if ctrl jack is not plugged-in) with adjustable thresholds (positive and negative). While input signal (or ctrl input) exceeds positive (or is below than negative) threshold then output is switched to DC level set by level knob (0-5V) or to external signal (then level knob serves as attenuator for external signal if ext in jack is plugged). Basially waveshaper with modulation capabilities. S-410 is DC coupled, low offset main signal path so it can be used for processing tuning CVs too. Internal jumper allows to select switch mode (signal is switched to ext/DC, jumper header removed) or mix mode (input signal is mixed with ext/DC, jumper header set).
Source – sine input:
Lowered positive threshold level, signal switched to DC level:
Positive threshold level lowered:
Both positive AND negative thresholds switches positive and negative peaks to same DC level:
DC level rised:
DC level slightly lowered:
Switched to (fast) external triangle signal:
Fast signal used as ctrl input, different positive and negative threshold settings (symmetrical and unsymmetrical, switched to DC level):
Another example – envelope processing:
Envelope peak switched to an DC level:
Peak switched to external triangle LFO creating more initial peaks:
Width: 4TE/ 4HP/ 20mm.
Depth: 40mm /1,6″ max.
Current: 20mA max.
Power cable included.
Double check power connection before powering your system please.
„Red strip“ means -12V connector side in Eurorack standards.
In some power distribution systems connector key can be reverted.
In this case cut connector key and plug power connector right way (with respect to red strip) or use different power cable appropriate to your power system.
