The Setup -
Unlike a few of the other USB audio devices we have tinkered with you do have to install a driver and utility to get the full benefit from the Rosewill RHM-6308. The installer is on the mini-CD that comes inside the box and while it does require a reboot it is a pretty solid little piece of software.
As you can see you have a few options for using the RHM-6308. You can opt for normal stereo or you can turn on the DSP (Digital Signal Processor) and run the system in 7.1 virtual surround. The other options include a small mixer, an effects page, a harmonizer (they call it magic voice), and more. Many of these options you would expect to find on more expensive audio products so we are pretty impressed to see them here.
