A small nice and handy program located on the taskbar allows for adjustments. It includes in particular a ten-band equalizer that can complement the tone control of the amp. The installation is made easy with Windows 7, though cobbled together by an exotic version of Asus. Just one thing: think of Creative define the card as the default device. Otherwise, although we hear something with, but the sound is lower and above the low saturate and cause a very strong intermodulation ...
Two little flaws:
1. We would have liked at least a high pass filter to cut infrasound which tend to saturate boomers sealed rooms. According to the instructions, it is in creative, but it's still petty not to provide it with this sound card, which is however not the first prize! I cut the 30Hz band on the equalizer, but I would have preferred a more fine tuning. Same with extreme treble. With age, one hears more and so avoid sending unnecessary in his ears decibels!
2. Switching speakers / headphones is done by the jack mechanism, and experience shows that it degrades quickly. Switching the mouse of the computer would have been preferable.
Conclusion: very pleased with this purchase anyway!
