Description
The KM22 half and KM33 quarter-track mono recorders appeared in early 1960 and were two-speed (3¾ and 1 ips) machines utilising a single Papst motor-driven Elektron TB491 deck.
Fitted with Bogen heads they boasted a true Hi-Fi frequency response of 30-16,000 cps at 3¾ ips.
Features included superimpose, pause, monitor and input mixing. A small internal speaker was incorporated but facilities were provided for connecting an external hi-fi speaker for superior reproduction.
Prices (when new) were 54gns for the two-track KM22 and 62gns for the four-track KM33.
