Tubbutec Sumtiple Kit Version – Construction Manual
This document describes the construction of the Sumtiple Kit. The following parts are
included:
• 1x Sumtiple PCB with SMD-Parts already soldered
• 1x Front panel
• 8x Jack sockets and nuts
• 1x RGB-LED
• 1x 10-Pin Header
• 1x Power supply cable
Tools needed to build Sumtiple:
• Soldering iron, solder
• Side cutter
• Pliers
• Multimeter for calibration
• Small screwdriver
Construction
First you should start with preparing the parts needed for proper construction. Check the
pictures for a better understanding of what needs to be done.
First take the jack sockets, you need to pinch off a little of each pin. The pins need to be
cut to a length of 1mm. If they are not short enough, they will stick out of the board and
may touch a module next to it.
The sockets should look like the one left in the pictures above. When you have prepared all
8 sockets, take the PCB and put the sockets on it like shown.

- Page 2 Now turn the board over. The easiest way, without all the sockets falling out, is to take a ruler and put it on top of the sockets, hold it with the PCB and turn it around. When you put it on the table, you can slide the sockets and PCB off the ruler. If you cut the pins to the right length, the PCB with the sockets should look something like this: You can see that the pins are level with the PCB and not sticking out (This should be the...
- Page 3 Use as little solder as possible or cut/pinch off the solder afterwards, so it looks like above. Check if the jacks are aligned, then you can solder the pins that are left, again, try to use as little solder as possible. Now take the RGB-LED.
- Page 4 The Sumtiple is almost finished. The board should look like this now. You can take the front panel, attach it to the board and screw the nuts to the jacks. Note the correct orientation of the front panel. You only need to calibrate the Sumtiple for the high precision and you are done!
- Page 5 Testing A quick test is recommended. Attach some voltage or signal to the summer inputs and measure all outputs. Calibration For calibration you need a DC voltage source of about 10V. The exact value is not important, anything between 9 – 10V is fine. You can also use a lower voltage, such as 5V, but that may result in a more difficult calibration.
