These classic, enduring, battery-operated portable hi-fi recorders were still going strong in 1980! During its 10 year life span (1973 – 1983) more than 600,000 were sold, many to organizations like NATO, The Ministry of Defence and the BBC.
Three versions were available- Stereo 1/4 track (4400) 1/2 track (4200)
Mono 1/4 track (4000).
All models had four tape speeds, tape tension regulation, Integrated Circuit (IC) power stage and an internal speaker. A rugged aluminium die-cast frame ensured stability and long-life (these recorders were used by NASA!) and made it an obvious choice for broadcast use.
A high speed motor ensured stability even in the event of vibration or movement and a speed accuracy of less than 1.5% was quoted. Wow & flutter was less than 0.20% at 7½ ips.
