The Muse 5.1 DVD software interface is spartan to say the least. Why didn't Hercules copy the interface on the Fortissimo II, a classic of its type? As you can see, it consists of a small gray strip containing the mixers for the outputs and inputs. It is very functional, but lacks the extra refinement to make it comfortable and easy to use, especially as the icons are not always self-explanatory. There is also a button for accessing more advanced choices. Click on it, and four tabs appear, marked Loudspeakers, Volume, Sound Effects, and Options.
