The concept of a combi-cable is simple: if you need to hook up gear with two types of cabling at once, then why not bundle them up in a neat combi-cable? For example, a combi-cable can combine a power and signal cable to efficiently link lighting fixtures, so you're setting up studio monitors, PA speakers, or lighting effects where audio and signal cables are required as well as power cables, then a combi-cable can really come in handy. These two-in-one problem-solvers basically wrap two different cables up in one, leaving the floor or rig clean and clear of any hazardous cable spaghetti.
