The Philips PSC805 Aurilium turns your PC or notebook into a 5.1 channel digital audio powerhouse by connecting only one cable – USB (2.0). Simplicity in a complicated world. Includes Intelligent Media Processing (IMP) where the award winning Sound Agent 2 audio software uses automatic jack detection to determine which speaker configuration is connected (e.g. 5.1 channel, 4.1 channel, 2.1 channel, stereo, headphone), analyses the input signal to determine which source is being played, and automatically applies the appropriate algorithm for optimal sound reproduction at all times.
