JOLIN TUTTO&SEMPRE Stereo Performance Mixer User Guide
Hi fellow!
Just a quick intro before starting,
what to have on hand
- Soldering Iron – better with temperature control
- Solder wire
- A pair of tweezers
- Cutter
- Multimeter (optional)
- Solder sucker / wick (optional)
- Silicone soldering mat (optional)
- Helping hands (optional)
- Flux (optional)
If you want to refresh yourself a bit about soldering stuff you can watch this video1 by GreatScott!
A tool that can help you checking the components on the board is the
interactive bill of materials.
Download the .html ibom file and open it with a browser. You can use it to
check where a component is located on the board.
Once downloaded it works fine also offline.
Here are listed all the TUTTO&SEMPRE components; most of them are already pre-
soldered on the surface of the board (SMD).
We just need to solder the through hole ones (THT).
BE CAREFUL NOT TO TOUCH THE SMD COMPONENTS WHILE SOLDERING THE THT ONES.
It’s really easy to lose a tiny SMD resistor or capacitor. Pay attention when
soldering parts that are close to others already in place.

Eurorack power header + JST headers
Place the socket and the headers matching the drawing on the PCB. Longer pins
needs to point outside. Careful on the JST header direction, check the
pictures if you have any doubts.
tip: solder one pin and check. If the socked is aligned with the PCB solder
all the other pins.
Optocouplers
Proceed placing and soldering the optocouplers matching the dot on top with the thick white line on the PCB as seen in the pictures.
DON’T MESS WITH THE TINY AND HELPLESS SMD COMPONENTS ALREADY SOLDERED ON THE BOARD
Good time for a pause: always good time to learn more about otters now flip the board (front layer):
Boxed switches
IMPORTANT – Follow the white marks on the silkscreen and the pictures below to get them in the right direction. The white springy thing on the switch has an uneven shape. Position it as shown in the pictures, with the empty square on the same side as the marking on the PCB. Proceed to solder them as flush and straight as possible.
tip: solder one pin and check. Align it with the PCB and solder all the other pin
Place the black round cap on the switches.
Jack sockets, toggle switches, potentiometers
Do not solder them: just place all of them in the right place and move to
the next step.
Be careful on the position of the green sockets. Follow the picture.
Toggle switches: to reduce clearance tighten one of the two nuts to the lever.
You don’t need the round locating ring.
Front panel
At last, put the panel on and tighten the nuts.
Now solder all the front panel components.
tip: we are soldering them now to ensure that all the mechanical parts are
aligned with the panel. This reduces the stress to the components.
Check if everything is in place and properly soldered.
Place the knobs, tighten their screws and we are officially done!
Have a good cup of coffee, you totally deserve it.
Before powering it up
-
It’s always a good practice to check the power header for shorts with a multimeter.
tip: follow this tutorial2 by Quincas Moreira – aka SynthDiyGuy if you have any doubts on how to perform the procedure. -
Mind the polarity on the header socket of your PSU, remember that red line is -12v
done! enjoy your new
