A-133 is a special dual voltage controlled amplifier that enables both positive and negative amplifications. Negative amplification means in this context that the signal is inverted. The main application of the module is the…

Module A-138c is a four channel mixer, that allows to add or to subtract four incoming voltages to the output signal. In the middle position of the corresponding control the amplification is zero. Turning the knob counterclockwise…

Module A-138e contains four identical units that can be used for different crossfading, mixing and polarizing applications:

∙ Polarizer: only input A is used, inputs B and C are unconnected. In this case the sub-unit works as a…

Module A-183-2 is a simple voltage offset generator combined with an attenuator/polarizer for the CV input. The function is similar to the vocoder slew-limiter module A-129-3. But the A-183-2 has only one channel available and…

QUAD CV INVERTER / AUDIO BUFFER IN 2HPEach output is a buffered negative version of the input. e.g. if an input is fed a 2v cv signal, the output will be a -2v signal.

All outputs are normalled to the inverter input below…

Module A-175 (Dual Voltage Inverter) is exactly what it says it is: two identical inverters, which will take a voltage and output it in an inverted form - so that an input of +5 V will be output as -5 V, an input of -2 V will be…

RIPLE ATTENUATOR, INVERTER, ATTENUVERTER AND DC VOLTAGE SOURCEThis is a utility module we found ourselves always needing and using. The three well spaced knobs can act as active attenuators, attenuverters (bipolar) and inverting…

Mutable Instruments Shades

Mixer, offset, attenuverterOverviewShades provides 3 channels of audio/CV processing which can be configured either as active attenuators or as attenuverters.

A bicolor LED monitors the polarity and…

WMD Invert Offset

The 6 HP Invert Offset module creates an easy way to modify control voltages for other modules in your system.

The Invert Offset consists of two identical channels. Signal applied to the In jack is vertically…

WMD/SSF Scale - Polarize - Offset (S.P.O)

S.P.O. is a polarizing scaler and offset generator.

Up to two inputs can be summed into a single scaler/offset generator.

The offset generator provides a DC voltage source for shifting…

WMD/SSF TOOL-BOX

TOOL-BOX is a collection of six useful synthesizer utilities.

This module includes a two input voltage summing section, a signal rectifier, bipolar comparator, analog OR (maximum), an inverter and a voltage…

Eowave Poles Dual CV Processor

This module contains two independent channels of essential CV processing. It can attenuate, invert, amplify (x2) and introduce a CV offset to CV or audio signal. If no cable is plugged into the…
