These natty cable jacks glow red for positive and green for negative polarity. Pretty and very useful in visualising voltages.
LED Eurorack Patchcables
All right so they are just patch cables but hey these ones light up! It’s an idea that’ been knocking around the Eurorack community for quite some time and turns up in cables from various sources. They look great and add some useful visual indication to what your signal is doing.
The problem is that in order to pass current through the LED you need to syphon off a bit of voltage from the signal. This means that the voltage that comes out of the end is not the same as that which went in the front. It’s not a big deal for most modulation purposes but would be bad for signals that require precision such as pitch as 1v/Oct.
ProducerTools.net say that they spent a lot of time working in the circuit for these cables and even had to design their own LED. They claim that there is “no measurable interference” in the signal. Can this be true? It seems unlikely but they appear to be confident that you won’t notice any drop in signal.
They are certainly a lot of fun.
These bi-colour LED patchcables cost €19.90 for a pack of 5 with black or transparent cables of 50cm in length. They are taking preorders now and hope ship in a week or two.
