Decent little unit. Perfect for recording live streaming dmx. While listening to music, you can record on this lighting recorder, and jam along with the lighting sliders, on your lighting desk, recording light changes in real time, for later playback to your music. It’s crazy they fit this with rack ears though?, it’s got so many essential plugs , on three of its four sides, powercom, dmx ins and outs, sd card slot etc, there’s no way you could ever fit this on any sort of rack. Too many cables in the way. Besides that?, a great little unit.
