I use this box to select between the output sound from my PC and my Xbox 360 (using conventional stereo RCA outputs), and redirect it to my little HIFI that accepts a line input. I hesitated a bit before purchasing this unit because I had read a review saying that the quality of housing was a little cheap. But in the end, once the gadget in hand, it turns out that it's pretty good stuff. The buttons have the beefy enough air: when pressed, it gives confidence; and nothing to spoil, finishes are clean (plastic shell, sockets behind). For hardware at that price, it was not won! Then I connected the whole, and - happiness - everything works perfectly: moving from an audio source to another in a flash, with a good level of comfort with change, sound sizzles and does not 'pétouille' no. The case does not take place, do not require external power, and perfectly fulfills its purpose for a ridiculous price. In short, it's all good !!
