Page 6: Preparing Miniprophet
Preparing MiniProphet First, locate the Power Board. It should look like this: The PowerBoard supplies MiniProphet’s VCO’s, VCF’s and envelopes with an additional +/- 5 volts. It does not need to be connected to the LFO’s. - Page 7 Then locate the double VCO module, and place it with its faceplate facing down:...
- Page 8 Now, mount the PowerBoard on the power connector of the double VCO module, using the 16 pin receptable header on the powerboard. Make sure that all 16 pins are perfectly alligned, and that the ”-12V” marks on both boards are alligned too.

- Page 10 Mount one of the 10-pole flatcables to the 10 pin connector on the top side of the double VCO module (this cable might come mounted). Make sure that all 10 pins are perfectly alligned, and that the brown cable are alligned to the same side as on the picture:...
- Page 11 (to the ”INPUT” mark on the PCB). When you mount MiniProphet in your Eurorack system, this cable should be connected to your Eurorack power bus, with...
- Page 12 Place the double VCF module with the faceplate facing down. Mount one of the 16- pole power flatcables on the powerconnector of this module (this cable might come mounted). Make sure that all of the 16 pins are perfectly alligned, and that the brown cable are alligned to the same side as on the picture (to the ”-12V”...
- Page 13 Connect the VCF power cable to the connector on the PowerBoard marked ”VCF”. Make sure that all of the 16 pins are perfectly alligned, and that the brown cable are alligned to the same side as on the picture (to the ”VCF” mark on the PowerBoard). Connect the 10 pole flat cable from the VCO to the 10 pin connector on the right side of the VCF.
- Page 14 Place the double Envelope module with the faceplate facing down. Mount one of the 16-pole power flatcables on the powerconnector of this module (this cable might come mounted). Make sure that all of the 16 pins are perfectly alligned, and that the brown cable are alligned to the same side as on the picture (to the ”-12V”...
- Page 15 VCF. Make sure that all of the 10 pins are perfectly alligned, and that the brown cable are pointing up, like on the picture. Your MiniProphet system are now ready to be installed in your Eurorack case. Connect the ”Input” power flatcable to the power bus of your eurorack case, with the...
- Page 16 (to the ”-12V” mark on the PCB). Connect this flatcable to the power bus of your eurorack case, with the brown cable alligned to pin 1 or –12V, and mount the double LFO module. Your MiniProphet system should now be ready to use.

Page 17: Inputs And Outputs Of The Modules
Midi In – 5 pole DIN connector. Connect the MIDI out of a MIDI keyboard, a MIDI sequencer, or any other MIDI device capable of transmitting notes and CC’s, to this. MiniProphet only receives Note on and off’s, pitch bend and modulation wheel messages on MIDI channel 2. - Page 18 PwmA – VCO A pulsewidth modulation. Connect any voltage generating source to this. The PwmA knob adjusts the amount of modulation. Cv1B, Cv2B – VCO B pitch modulation. Connect any voltage generating source to these. The Cv1B and Cv2B knobs adjusts the amount of modulation. PwmB –...

Page 19: The Double Vcf
The Double VCF Inputs: SquA, TriA, SawA, SquB, TriB, SawB – Double filter input mixer. Connect any audio signals you want routed through the 2 filters, to these. The respective knobs controls the audio signal levels. When nothing are connected to these, the outputs of VCO A and B are internally connected to them. - Page 20 Cv2(env2) – VCF 1 and 2 CutOff frequency modulation. Connect any voltage generating source to this. The Cv2 knob adjusts the amount of modulation. This modulation applies to both VCF1 and 2 at the same time. When the ”Vcf2” switch are in the ”Inv”...

Page 21: The Double Envelope
The Double Envelope Inputs: Gate – Triggers the 2 envelopes to start from zero, and go through the ADSR stages. Outputs: Env1, Env2 – Envelope 1 and 2 voltage outputs. -
Page 22: The Double Lfo
The Double LFO Inputs: Cv – LFO Rate modulation. Connect any voltage generating source to this. The Cv knob adjusts the amount of modulation. Outputs: Tri, Squ – Triangle and square wave outputs. The rate of these can be adjusted using the Rate knob and the Rate Cv input. -
Page 23: Internal Connections
Internal Connections If you have connected the 2 10-pole flatcables, as described earlier in this manual, MiniProphet will have some internal connections. These are cutted off, by plugging something in to their respective inputs. List of internal connections: -All 6 oscillator output waveforms are internally connected to the filters input mixer. - Page 24 www.gotharman.dk...
