Modules 5 and 16 – WORNG Electronics 3x3x3 Passive Mult

  • What kind of thing is it? A passive multiple. A mult lets you send whatever signal is travelling down a cable to multiple different destinations. Using a passive mult, the signal weakens the more places you send it to but for on-off signals like triggers and clocks, that doesn’t matter so much.
  • How is it useful? You can send one signal up to six new places, three signals out to two new places each, and with two signals you can send one to four other places and one to two other places. Here are some pictures with captions.

The 3x3x3’s input jacks all have a gold ring around them. Here it is fully connected. Yellow’s signal is going out to the pinks; green’s signal is going out to the whites and blue’s signal is going out to the reds.

Now we only have two inputs. Yellow’s signal still goes out through the pinks. Green’s signal goes out through the whites, and since there’s nothing plugged in under the whites it goes out through the reds too.

Yellow’s signal is still going out through the pinks, but since nothing is plugged in under pink, the white cables also carry yellow’s signal. The blue cable’s signal is carried down the red cables.

With no other input voltages, the yellow cable’s voltage (at the top) is being sent out to pink, yellow and red all at once.

  • How does it work? By joining switching audio jacks together on a circuitboard. Seriously, that’s all there is to it. They don’t come much simpler.
  • Does it work well? Definitely. This was the first module I ever got two of, even.
  • Are you still using it? I’ve replaced one of these with some Befaco six-way mults which live in the cable spaghetti. The other one is still racked up for now until I get some more six-way mults.
  • It’s a kit – how easy was it to build? It’s inexpensive to buy, safe and simple to build as an early DIY project and very useful – an ideal first DIY Eurorack module, I think! The only build problem I had was attaching the panel upside-down but that was easily rectified. 🙂
  • Surprises/disappointments? It works even better de-racked and living in cable-space!

The white cable is carrying a repeating falling voltage used to make a kick drum. Sent through the mult, the pink leads use the same signal to make the oscillator go PEW and also reset its sync to avoid clcks on some triggers and not on others because of interactions between the oscillator’s phase and the amplifier’s envelope. Without the mult, I’d need two separate envelope generators. Bargain!
