The TLN-861 Dunsel is a utility module that generates several commonly used signals from an input voltage. When patching my synth, I frequently require unity gain inverters, adders, subtractors, half/full wave recitifiers, and level shifters. While it's possible to generate these signals using MOTM-830, Oakley WaveFolder, or Oakley Multimix modules, that's not often the best use of those resources. Enter Captain Dunsel to the rescue.
The Dunsel features two channels (A & B) with the following independant outputs:
The Dunsel also has the following combined outputs:
- INV A/B: unity gain inversion of input.
- NEG A/B: negative portion of input.
- POS A/B: positive portion of input (half wave rectification).
- FWR A/B: full wave rectified version of input.
- A/B - 5: level shifted version of input (-5V level shift).
- A/B + 5: level shifted version of input (+5V level shift).
- A + B: sum of A and B inputs.
- A - B: difference of A and B inputs.
The TLN-861 Dunsel can be built using MUUB daughterboards. The first version I built (Rev 1) used four MUUB-4 boards and three MUUB-2 boards stacked two or three boards high. That version was a bit cumbersome to put together. I then realized I could simplify things considerably by using two MUUB-3 boards and one MUUB-2 board (Rev 2).

Total current draw for TLN-861 is 38 mA @+15V and 38 mA @-15V.
