Have previously tried 3 other switches, each 4x2, partly indication was Sky suitable here, but it ran only the normal channels on the Skyreciever, the Cinema channels did not run! This product expressly stands that Sky + runs and it runs really! Had some problems ersmal connect at until he could drive projectors and televisions, bit arg many buttons and lights, as I get technical support and have again taken me time .... that part works just fine! TV and projectors running simultaneously or separately from each other! Have Sky, DVD and Amazon Fire TV connected, everything works! In addition, can be removed via the output A audio directly on the switch and run on a system, I first made with the jack, funtkionierte super, did the same to me ordered the optical cable and connected, now have 5.1 sound on de stereo when I look at the beamer whether TV, Amazon or DVD, when I look at the television, the sound coming through the TV speakers, that must be enough! Am currently very enthusiastic!
Weaknesses: the part is cal ... s warm, he hoped not burn sometime by! Reacts very slowly when switching and remains first hang briefly, then läufts but! Oh, and the many irritating lights, but at least not as bright as some other device!
