Arrived fast and well packed. First seemed a problem, as just a small green light flashed for a fraction of a second by pushing volume control. Nothing else. May be because of a less powerfull power supply (12V 1A). The volume meter has no start/stop position, you can turn it around. Then when inserted a pendrive suddenly switched on, 2 strong green lights appears with the LED panel. After that everithing worked fine, all input works as it must be. I used with a Roadstar 4Ohm 24W sound box pair as seen on photos. I have ordered a 24V 5Apower supply to try it with my 100W sound box pair (using it with a 180W amplifier now). But I am quite satisfied with my 24W boxes, I will use this tiny box with those.
