Description
These were battery-operated portable hi-fi stereos (4400 quarter-track and 4200 half -track). The model 4000 was a hi-fi quarter-track mono. 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. In excess of 600,000 of these durable machines were sold over a sixteen year production cycle. 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.
All models could be powered off single cell, car or rechargeable battery or by mains power supply unit.
