Heinakroon LED Slimline patch cables, 5-pack

These slimline LED cables are perfect for patching your modular system or semi-modular synths. The high-quality black patch cables have colored LED lights in each jack connector that lights up when a signal is passed through the cable. This makes it very easy to see what’s going on in a patch, and is useful for both diagnostics and education.

The LED patch cables are fully compatible with 3.5mm mini jack sockets in any Eurorack system or semi-modular synth, as well as other musical instruments that use 3.5mm mini jacks. The cables feature metal barrels that are very slim, only 8mm/0.3 inch in diameter, allowing them to fit in even the most cramped modular system.

Each jack connector has a built-in LED that lights up when a signal is going through the cable. The jack connectors show green lights for positive voltages and red lights for negative. This makes it extremely easy to see what kind of signal that’s being passed through the cable which is useful for diagnosing complex patches.

The LED cables come in either 11.8 inch (30cm) or 23.6 inch (60cm) lengths. These lengths are among the most popular for Eurorack patch cables, with the shorter ones working well within a patchbay or between neighboring modules, and the longer cables better for reaching between modules spaced further apart.

These cables will help you with diagnostics of patches, making it easy to see what’s going on – especially since the two jacks have inverted LED colors. At the same time, this also makes these cables ideal for teaching modular synthesis and other educational scenarios, and beginners will appreciate the intuitive guiding the LED lights provide.

LED patch cables makes it easy to patch your synths even in dark conditions, like on stage or in a darkened studio. The flashing LEDs will also add a certain flair to your performance, with the rhythm of your music enforced by the red and green LED lights across your patch.
