A lot has changed in the world of lighting engineering since the arrival of the DMX 512 system. Where you used to have to lug heavy multicables around, now you can simply daisy chain all of your cables with the help of a DMX cable. The DMX cables in this category have a resistance of 110 Ohms, which is vital to reducing the chance of interference. Regular XLR cables will also work, but they might cause odd side effects when used over longer distances and when used with different types of devices.
