The any:diff module makes it possible to subtract one voltage from another. On two channels. This module can be used to generate more complex control voltages and audio signals.
This module is very simple to build and therefore an easy project for beginners.
If you are new to building DIY kits you may have a look at our brief Soldering Tutorial.

STEP BY STEP

The following components should have been included in the kit
(from left to right):
- 1 panel
- 6 jack sockets
- 1 printed circuit board
- 3 electrolytic capacitors
- 1 IDC socket 16 pin

Step 1: Fitting the jack sockets

Step 2: Equip the IDC socket
Attention: Polarity does matter! Pin 1 of the socket is marked on the PCB as well as the notch in the middle.


Some components must be placed in the correct orientation.
Left image: the jack has a notch which must be aligned to the notch of the footprint.
Right image: electrolytic capacitors have a big stripe with minus signs marking the negative side of the component. The footprint often indicates its positive pin with a small plus sign. Make sure to place electrolytic capacitors with minus pin to minus hole and plus pin to plus hole.

Step 3: Fitting the capacitors.
Attention: Polarity does matter! The capacitors are marked on their negative side, so make sure this matches the printed footprint.
Step 4: Fastening the panel using the six screws on the jack sockets.
