NV-301/701 The NV-301 and NV-701 both shared a three-layered half-mirrored design with the main difference lying in the specification of the two systems. The NV-301 was the basic model with two speakers and with a line input (marked for MiniDisc and DVD players) while the NV-701 was a 5.1 Dolby surround sound model with A/V inputs. Both featured a three-disc carousel, a cassette player with Dolby B noise reduction, a natural display, intelligent features and the ability to save up to 40 radio stations, utilising microcomputers to reduce the size of the unit.
