Windows Driver Software for HP-A8 

HP-A8C complies with USB Audio Class 2.0. In case of use with Windows

that has not complied with USB Audio Class 2.0 so far, the driver software

for HP-A8C (for Windows XP or later) is necessary, which can be down-

loaded from the Fostex website.  The driver must be installed before the 

HP-A8 is connected to PC. MacOS (10.6 or later) complying with USB Audio

Class 2.0 does not require the driver software.
