Our minimalist Charterhouse Console is proving to be very popular; it appeals to organists who want a price of elegant furniture rather a traditional box.
The customer used a a Mac Mini was used with 2 M-Audio BX8 Carbon speakers connected directly to the headphone jack. This configuration works really well on a Mac.
One issue we had during installation was with the USB hub that was connected to the 2 Iiyama touch screens. The Mac Mini has USB 3 ports and connecting them to an non-powered USB 2 hub can yield some very strange behaviour and also generated significant audio interference.
