SISM

4ms

Manipulate CV and audio signals with the 4ms Shifting Inverting Signal Mingler, a 4-channel voltage manipulator Eurorack module that can scale, invert, attenuate, shift (DC offset), mix, split, and slice control voltage and audio signals. Each of the four channels are independent and have an input and output jack, a knob for attenuating/inverting (Scale), a knob for applying positive or negative DC offset (Shift), and two LEDs. Four jacks on the bottom combine the four channels in different ways. The SISM ships with a ribbon power cable and mounting screws.Basic Overview Four independent voltage processor channels and four mix/mingle outputsEach channel has:Input jackSCALE knob (from inverted unity, to zero, to unity), center detentedSHIFT knob (adds/subtracts DC offset from -9.5V to +9.5V), center detentedOutput jackRed and blue LEDs indicate positive and negative signal, respectively. Brighter means more voltage, dimmer means lessMIX jack outputs sum of all channelsMIX Switch jack outputs sum of all channels with nothing plugged into their output jack+SLICE jack outputs positive portion of mix (voltages greater than 0V)- SLICE jack outputs negative portion of mix (voltages less than 0V)Red and blue LEDs on all four mix/mingle jacks indicate positive and negative signal, respectively. Brighter means more voltage, dimmer means lessAdvanced Features Inputs for channels 1+2 and 3+4 are normalized together:Plugging into Channel 1 (or 3) will split the signal to channels 1 and 2 (or to 3 and 4)A jumper on the back enables/disables this normalization Scale knob has three ranges that are selectable with jumpers:Bipolar: -1x to +1x (inverting unity to unity) defaultUnipolar: 0 to +1x (level fader)Boost: 0 to +2x (twice the voltage gain)Input Header (2x4):Connects the output of a QCD or QPLFO to the SISM's inputsPlugging into the SISM input jacks overrides the signal on the headerOutput Header (2x4)Connects the SISM's channel outputs to the input of a VCA Matrix or other compatible module (Mixiplexer or Intermix)PAD breakout header (2x4)Can connect to an external DIY module that enables a preset pad (attenuation) on each channelUsage Attenuator (quad)Inverter (quad)Level shifter/DC offset (quad)Mixer (4 inputs)Splitter (dual 1-2, or single 1-4 using a stackcable or passive mult)Bipolar audio mixing: Useful for mixing various filter outputs with the original signal to create new filter curvesVoltage slicer: + and - portions are separated and outputted to the + and - SLICE jacksDirty panning: apply a large slow wave to one channel, and the other channels will pan between the SLICE jacks. The signals are half-wave rectified as they span both outputsLFO mingler: connect QPLFO outputs to SISM inputsSequencer: connect QCD outputs to SISM inputs (or any clock divider/multiplier) and take the sequencer output from the MIX jackAdd attenuation and inversion to any CV jack on other modulesKeep all your fine-tuning controls for several modules in one placeManual voltage generator. With no input connected, each channel outputs a steady DC voltage controlled by the SHIFT knobEurorack Ready 12 HP Eurorack format moduleMaximum Depth: 0.86" (22mm)Includes power ribbon cable with 16-pin Eurorack power headerPower consumption: +12V: 51mA, -12V: 51mA
