Fixed voltage source with BIG KNOBS and multiple voltage ranges


Fixed voltage sources are not a new idea in modular, but we hope that Turn! Turn! brings a new twist to the concept. Turn! Turn! features two independent fixed voltage sources with a useful range of features.

Turn! Turn! grew out of a conversation with Steve Levine – when a producer of such note makes a suggestion you have to listen – and act on it. Steve suggested that it would be useful to have a fixed voltage source under the control of a big knob, and the ability to go from as little as 1V over the entire range of the knob. Hence subtle, incremental changes are possible.

The final feature set includes a voltage selection switch as well as a unipolar/bipolar switch. Both normal and inverted outputs are included. The following ranges are available from Turn! Turn! depending on switch positions:

  • 0V to 1V
  • 0V to 2.5V
  • 0V to 5V
  • -1V to 1V
  • -2.5V to 2.5V
  • -5V to 5V
