...
- install the resistors and diodes
- install the ceramic capacitors (not the electrolyte caps yet)
- install the TO-220 regulators (IC4, IC5, IC7), the black isolated regulators do not match with the pcb holes, its not important. bend the pins as short as possible that they can be soldered from the rear-side of the pcb
- install IC3 - I prefer without a socket for better thermal regulation, but should be fine with a socket too.
- install the electrolyte caps
- install the LEDs - LED orientation - the square pad is ground (short leg) its the flat side of the LED designator
- install the fuse socket and MTA 156 2pole header
- install the DC-DC bricks (IC1, IC2)
- Double check the IC orientation and part values, Capacitor polarity
- wash the PCB carefully and let they dry over night
- optional - use a bench psu for testing with current limiter 12v /250mA 250- 500mA don't use a smaller current limit to avoid problems while start, the 250mA is a given value without any devices connected
- must do: all LEDs must be on, check against the given PCB voltages - all voltages must be correctcheck against the given PCB voltages - all voltages must be correct
- Install the Heatsink by the self adhesive tape and push the heatsink against the DC-DC for 20-30seconds (new task since 24.Nov.2022)
first test on a bench PSU with current limit at 12v/200mA
Breakoutboard (BB)
Start with the SMT parts on the rear side and IC4.
...
- install the SMT capacitors as before described in the Breakoutboard section.
- install the SMT ICs
- install the resistors - solder all pins, do not install the Tempco Resistor yet
- install the ceramic capacitors - solder all pins
- install the IC sockets - standard IC sockets preferred - solder all pins after you have checked the alignment
- install the matched Transistor pair (2N3904), regulators - do not overheat the pins here
- look in my above guide - about the 240pf capacitors - maybe you have to select or match something - its not needed but for some builders just a notice
- install the Filmcapacitors/Electrolyte caps and solder one pin - align the capacitors before you solder the second pins.
- wash the pcbs as described before
- when the pcbs are dry - install the Trimmers
- install all ICS
- install the Tempco resistors - this must be thermal connected, use thermal paste
- use shrink tube for the 2N3904 pair and thermal paste
- double and triple check the IC orientation
Hardwareboard part 2: (read this before you start)
- install the 12mm spacer on the HW.board,
- then put on the mainboard the opposite part
- then put the boards together and fix the pcbs with few screws on the spacers
- then solder the 10pin dual row header/socket all pins - solder both parts completely before you remove the pcbs again (otherwise some pins can be accidentally removed)
- clean these solderpoints with eartips carefully.
- remove the screws and disassembly the pcbs
- --------
- install the sliders on the Hardware Board, and carefully solder them - pin by pin - as described in the above table (do not overheat the parts)
...
10. the last parts can be installed with one step or step by step - but in this case, you have to remove the frontpanel a few times. (customers with experience from DDRM/Kijimi can try to install the pots, OLED, LEDs, tactiles and the tactile caps in one step)
11. cut/remove the locker pin on the potentiometers potentiometers
12. the potentiometer must be installed with the front panel attached for best alignmentbest alignment - please note: one Potentiometer is not Center detent !! its marked on the pcb without an line in the circle.(volume pot)
13. the potentiometer have to sit on the pcb - do not try to to install the potentiometers in a higher position (or you can run in problems with the knob height)
...
(0.5mm2 is fine too since I used in my calculation 1meter and 2Amps)
testing
Test the PSU without BB - on a bench psu with current limiter 250mA only the PSU.
with mainboard connected 1000mA (without Voicecard)
with one card try 1000mA- with all cards up to 2.000mA
The OLED and LEDs will only work after you have installed the Firmware !! (some leds are on without the firmware)

Here is a step by step guide to calibrate the filter resonance: (ONLY AFTER that you need to calibrate filters in further step)It´s recommend turning the resonance trimmer TR1 fully clockwise on each voicecard to make this procedure as easy as possible!  The best way is to use 8 resistors on the mainboard for making a measurement. 1. Warm up your unit about 30-40 mins 2. turn on ISE-NIN, Go to menu (press shift (grey cap button) + Back (middle button under the display), then calibration, choose CROSSMOD then press SHIFT and press the encoder, this will add the hidden RESONANCE and CROSSMOD TRIM function (its hidden since prebuilt units do not need this) (The display should read: "card 1" and you should hear a test tone through the outputs (for the next voice card you can press the "next (Back)" button to cycle through the voice cards) 3. Connect a Scope probe on the Mainboard, to the resistor of the card which you calibrate , set your oscilloscope to "timebase 0.5ms/cm" and "1V/cm" (on DMM: 0.5V -1V is fine too, depends on your scope screen resolution - some new scopes are HD resolution in 720p or more and the ADC are very accurat) 4. You should see the filter signal on your scope. If you have turned the trimmer fully clockwise the signal should be- and sound distorted. now turn the "resonance" trimmer TR1 on the Voicecard anti- clockwise until you get a clean signal as in the picture below (The difference of maximum and minimum amplitude in one cycle has to be 4-times.) make sure to have enough gain otherwise the Filter calibration step will fail as described in next section. Comment from Black Corp: "We especially made all settings in resonanse calibration how they should be (square, cutoff, 12db etc)."
Congratulations, you have successfilly calibrated the filter resonance for all of the voices! Resonance calibration Method according to the Roland Jupiter-8 service manual (not recommended yet → use above method!!!):Go into MENU, CALIBRATION, RESONANCE. Follow these steps from the Jupiter 8 manual, turning Trim1 for each voice (or see below):
Workaround or turn Trim TR1 until the self oscillation is off on each voice. you can switch between the cards using the switch button on the mother board. |

you have to finish the resonance calibration before you proceed further with this step but read the Help in this section, to avoid problems. Go into MENU, FILTER, CALIBRATION, press "run" (push the encoder or enter by a pushbutton) Help: in case the Frequency stuck at "37Hz" or "no Signal" is on the OLED shown, you have to turn the resonance trimmer clockwise to have more gain - your resonance calibration was wrong. if you still have issues, look in the Troubleshooting page Technical Background: some filter designs have the possibility to make sounds byself, the Filter can act as a Oscillator (for example percussive sounds or bass drums). Since we have a oscillator function in Filters, we can control them v/oct based for example, that's what we calibrate automatically in the ISE-NIN filter calibration method. the Frequency Calibration is a V/Oct based Modulation which use the Filter Oscillation signal (resonance), the ISE-NIN calibration software need this signal, only with enough gain it can be analyzed and . | ||
