You are confusing digital signal processing with digital -> analog conversion. The HU doesn't have to decode anything to play an analog signal - it simply amplifies it and sends it to the speakers. I'm not sure about the Logic7 control though - who knows, it may convert the signal back to digital again, do some processing, and then spit out an analog signal again. But I'm not sure...
