The Zektor I use is actually an older model than the one in the eBay listing. However they are functionally equivalent in that they use passive relay switching, no signal processing. Also my unit can be & is IR remote controlled. The Zektor does not come with a remote & how they accomplish this is rather clever. We all know how universal remotes are "learning" remotes and that's been applied in reverse to the switcher. In other words put the Zektor in learning mode & teach it that your remote button A is the 1st input, button B is the 2nd input, etc.I’ve read that Involve is considering a MCH audio to HDMI converter, although they seem to be encountering issues with licensing payments and circuit board layout. I’ve been considering a similar garage shop project myself, but it’s a year or two down the road.
Such a device would allow me to use some of the open inputs on my Marantz pre-pro as quad selector switches, but in the meantime I figure I will use some sort of IR controlled relay box, with all the wiring that that will entail.
I will stop working on the room when I stop breathing.
