Passive Multiples are among the simplest and most essential modules you can find in a modular synth. You really need plenty of them!
A multiple simply allows you to share signals between modules: From the output of one module to multiple inputs.
A passive multiple means that the signal is simply shared without any electronic modification. Also, you don’t need to power it. It won’t draw any current.
Passive Multiple is made of two independent or chained sub circuits. You can choose between the two modes by adding or removing a small blob of solder on the back of the PCB.
Any jack in a sub circuit can act as the input and as an output. It’s important to connect only one module output to the Passive Multiple input.
If you connect two outputs to the same sub circuit, it could damage the weakest module’s output.
In principle, outputs on commercial modules are protected, but you never know.
In chained mode (see above, how to select the mode), it is possible to daisy chain several Passive Multiple sub circuits. If jack n°5 is unconnected, the input signal can be delivered by sub circuit #1.
Plugging in a jack in connector J5 disconnects the sub circuit #2 from sub circuit #1.
