Doepfer A-175

Dual Voltage Inverter

  • Dual voltage inverter
  • When applied to the input, the voltage is inverted (for example from 5 V to -5 V inversion) and is available at the output
  • Two LEDs are used for voltage control of the output signal (positive / negative)
  • Width: 4 TE / 4 HP / 20.0 mm
  • Depth: 35 mm (measured from the rear of the front panel)
  • Power requirements: 20 mA (12 V) / -10 mA (-12 V)

an indispensable utility

23.10.2016
Seems like a simple little module but I'm surprised how often this ends up in my patches.

Inverts the voltage at the input and outputs the original voltage and the inverted voltage, simple. But think laterally and it's a powerful addition to any system. With a couple of VCAs an LFO's signal can be used to create a panning effect or if you need to invert a clock signal this'll do the trick. I like inverting a sample and hold voltage then routing the two control voltages to two filters.

It's inexpensive, indispensable and you get two inverters in one small module.

Does exactly what it says on the tin

Simon P, 29.07.2013
This is an incredibly useful module. It's not filled with loads of features or anything like that. But what it does it does well and is an invaluable part of my set up.

By looking at the front panel it's not obvious, but if you put a source into the top 'in' and nothing in the second 'in' then you can not only take the inverted out, but a copy of the input source too. So it's also a mult. Bonus.
