Description

The TLN-861 Dunsel is a utility module that generates several commonly used signals from an input voltage. When patching my synth, I find I constantly 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:
  • 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).
The Dunsel also has the following combined outputs:
  • 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.

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

The User Guide does not contain detailed explanations on how to install parts or which kinds of solder to use. The intended audience is the experienced kit builder who is quite comfortable building a circuit from a description, a parts list, and a schematic. Calibration routines are included.

I hope to get MOTM-style front panels made in 2007 from Stooge Panels.
