I came across this cable when I a saw the sound guy at a gig using it for floor monitors. I was pleasantly surprised at the neatness it brings to the stage by eliminating separate cables for power and audio.
I was happy to find that the same cable was available at Thomann and ordered it right away to change all the power/audio cables that we were using on our church stage.
Thomann sells the cable in bulk and you need to buy all the necessary plugs according to your need. All I had to do was to cut the cable according to my stage requirements and solder away.
It is very easy to prepare the cable for soldering and all you need is basic wire cutter and a utility knife although remember to use shrink tubing to give a cleaner look and to keep the separate cables from damage.
This cable is very solid and excellent in quality, there are no noise issues due to the cable having good shielding.
I highly recommend this cable for stage monitors or any other powered speaker where you need audio and power cables.
