Compact. Clear. Capable.The Shakmat SumDif is a versatile 2HP dual adder and differentiator designed for both CV and audio tasks. Whether you're mixing voltages, inverting signals, or venturing into Mid/Side audio processing, SumDif delivers sharp accuracy with a minimal footprint. Each channel handles A+B and A–B operations, allowing use as a unity mixer, buffered multiple, or inverter. With precision signal handling and support for V/oct signals, it's a trusted tool for modulation and pitch duties alike. Rear jumpers allow optional -6dB attenuation for refined output control. Features Dual adder/differentiator for CV and audio signals Simultaneous A+B (sum) and A–B (difference) outputs Functions as a unity mixer, signal inverter, or buffered multiple Mid/Side audio processing ready -6dB output attenuation via rear jumpers Skiff-friendly design (29mm deep) V/oct accurate signal handling Technical Specifications Width: 2HP Depth: 29mm Power consumption: +12V: 15mA, -12V: 15mA Applications CV signal routing and conditioning Mid/Side processing in audio chains Pitch signal mixing and inversionSmall module, maximum impact.
