His very pure!

Very good sound card came with its extension cable, a driver CD and parameter control software, very complete. While a bit expensive for such a small USB card but good, quality has a price. Do not be deluded by the two small blue lights shaped speaker. These are just light operating witnesses. To return to the sound, I would have liked a surround function but with some customized settings can be saved under different names this will largely compensate for this "lack". A small thing, I have a very good original sound card on my Asus motherboard, however this one is more accurate in the settings and return of various instruments or voices. It has been recognized on Windows 7, but it took install the drivers and software CD to enjoy it fully. It has a function to boost its power, it means that you have power in reserve under the foot. Who can do more can do less.
