Is there an easy way to freely connect several music sources and their multiple receivers at home? Yes! Even if entire environment should be integrated with a COAXIAL-SPDIF switch for the audiophile sound quality? Sure, recently I built the switch that can do that. But now it's time for the main question, is there the easiest and most intuitive way in the world to manage required connecions? To allow anyone seeing it for the first time to control it without any learning? Of course, now there is! All I needed to breathe a new life into my music center is the HMI panel from Elecrow.
