Promoted as a "home studio" stereo recorder/amplifier, the N4450 was a three-speed quarter-track recorder designed for vertical or horizontal operation and had automatic and manual reverse.

An electronically-controlled Hall brushless DC motor was used for the capstan drive and two DC air-gap motors for the two spools, which provided tension so that no mechanical friction on the spools was necessary.

Six heads were fitted, an erase, record and playback for each direction and all transport functions were solenoid-controlled.

Reels up to 10½ inches were accommodated and the built-in stereo amplifier delivered 20 watts per channel. The motors could be turned off for amplifier use only.

Other features included a three-step fast winding speed control, transparent sliding level controls, remote control capability, an in-built splicing device underneath the head cover and a built-in synchronous clock with programmable start/stop functionality.
