With the longest variety of 5" tape (1800 ft. [549 m] long), and using four-track mono at 15/16 i.p.s., it would be possible to get about 24 hours' recording time on one reel of tape, albeit at poor quality suitable only for speech, and 6 hours' continuous recording time would be possible.
Even German and European television tended despite outfitting their radio reports with 4000-series machines to adopt Nagra or Stellavox recorders for film production.

They had several sources of power: The Royal de Luxe series was targeted at the home market.
