yup, i using Win 7 64-bit Ultimate. it will already come with the bass boost? may i know where to configure it
this used unit is been used around 1 year +

seldom use one
go to your volume control options... (commonly on the bottom right side of your screen. If not then control panel and search for 'sound')
double click it will show you the available soundcards connected.
choose the one you are currently using and double click it.
see if there is an 'Enhancements' tab there or not. (not all soundcards (especially built in ones) have them but most external ones should have it)
my dell with SRS audio does not have bass boost function but the SRS will do the job
but when I plug my T-Muso soundcard it provides bass boost feature.
