I bought this adapter to modify it, so that I get separate left and right channels on the 6,3mm jacks. I use it to plug two patch cables (left and right channel from a mixer) to the Atem mini video switcher. Modifying it was very easy, as the jacks can be easily unscrewed and opened. All you need is some basic soldering skills. The contact on the 6,3mm jacks is really good with patch cables, it doesn't crackle. Be aware that after you modify it, you void the warranty. But it's definitely worth a try!
