Introduction: Passive Multiple

By Livestock Electronics
About: We are a modular synth startup company from the Netherlands. Our instructables consist of easy, yet fun DIY modules made from a couple of components. Visit our website to see our other modules!

The passive multiple (or splitter) is by far the easiest module to build yourself. It splits the signal from one of the connected sockets to the other sockets. The amount of "splitters" and outputs can depend on your needs, but it may be possible that the source is eventually not capable of enough current when a lot of outputs are connected.

For this instructable I have created a 3x 1:2 multiple.

What you will need:

- Solder iron

- Solder tin

- Conductive wire

- Ruler

- A couple of sockets (I used 9 from thonk: https://www.thonk.co.uk/shop/3-5mm-jacks/)

- Panel (I created one from plexiglass, 2 or 2,5 mm)

- Drill with 3M and 6M bit

Step 1: Prepare Your Panel

Depending on your socket size, you can decide on the amount of HP for the multiple. I have used 3HP width, which is 0,6 inch or 15,24 mm (1HP is equal to 0,2 inch). More info on this here: http://www.doepfer.de/a100_man/a100m_e.htm

- Place the sockets on the desired spot and draw where you want to make the holes for the sockets. (The thonkiconn sockets have the inputs to one side when placed horizontally, so remember this when locating the spots for the sockets).

Also remember that you need to stay away from the top and bottom of the panel for about 1 cm as this is where the mounting rails will be!

- Drill the holes for the sockets (with the 6M drill).

- Drill the holes for the screws (with the 3M drill) with its centre about 7,5mm from the left side and 3mm from the top or bottom of the panel.

- Mount the sockets onto the panel, facing the same direction.

Step 2: Solder the Pins Together

You can use the conductive wire to connect one pin to another pin, as in the pictures. Optionally use a "helping soldering stand" to keep everything in place.

At this point you can choose how many sockets you connect together. As you can see I did this for three sockets each time...

- Solder the pins on one side of the sockets together.

- Solder the pins on the other side of the sockets together.

That's it! Have fun passively multiplying signals!
