SD-9020 Superscope didn't need any help to make full-size Christmas trees and this is what one could easily call... tacky ! Before seeing a brief ESOTEC version (SD-7), the Compudeck SD-9020 boasted a quickly passing fad of the late 1970s : 9,5cm/s double-speed transports. If that upgrade to the old Philips Compact Cassette standard did allow for extended frequency response and improved signal-to-noise ratios, the drawback was an increased resonance from the heads, leading to peaking some frequencies as the heads weren't expressly developped for that upgrade... The SD-8020 is a two-head version of the SD-9020. Both only had two motors but nevertheless sported the "Sensor Stop" buttons flanking the cassette compartment which would stop the transport as soon as one would take the cassette off the deck. If memory serves me well, at least Sansui and Pioneer had that feature incorporated into some of their own decks at the time. The SD-9000dbx is a later version : without double-speed (aha!) but adding the supreme dbx noise-reduction system. The
RMC-1 wired control plugs to
the back with an RS-232 plug.
Optional RHA-8 rack mounting
handles could be purchased for the ultimate in pro looks. I don't know yet who really built the SD series for Superscope but suspect one of the asian OEM'ers such as Tatung. After Philips' partial takeover in 1979, it isn't Philips who built the Marantz cassette decks but... another OEM supplier ;-) |
