- Primul CD-player comercializat din lume (prototipul a fost prezentat in 1979 -v. rev Klang bild 05.1979) ; un alt aparat "revolutionar", prin: (I) conceptia tehnica (utilizeaza raza de lumina laser ca suport de semnal, neavand piese in frecare); (II) calitatea excelenta a sunetului, disponibila marelui public; (III) deschiderea unor noi orizonturi in tehnica audio - minidisc, mp3, etc; (IV) calitatea superioara a suportului folosit comparativ cu a benzii magnetice; din caract. tehnice: gama de frecvente redate: 20 - 20.000 (nivel profesional); dinamica si raport semnal/zgomot: > 90 db (nivele profesionale); separare intre canale: >86 db (nivel profesional); tip laser utilizat: AIGaAs, cu semiconductori; frecventa de lucru: 44,1 hz; conversia digital/analog: 16 bit; sincronizarea fluctuatiilor: cu cuart de precizie; consum: cca. 20 W; pret la data aparitiei: 2000 DM (=cca 75% din salariul mediu din Germania de vest); constructie robusta (mecanica si sasiu metalice) si foarte fiabila (citeste c-discuri pe care aparate actuale le resping);
aparitia lui a marcat inceputul declinului benzii magnetice - un suport mai slab din toate punctele de vedere.
(desi nu este un casetofon, locul sau in acesta colectie este motivat prin dorinta/necesitatea de prezentare inclusiv a "adversarilor" sai);
functional ; cu manuale de operare si reparatie;

-a technical revolution : first Compact Disc player marketed in the world (the project/prototype was presented in 1979 !); new technique, HIFI sound, new audio horizons, better audio medium than the tape; freq. range: 20 - 20.000 Hz ; signal-to- noise ratio. 90 db ( !! ) ; metal chasis; working frequency: 44.1 Hz ; issuing price: 2000 DM (ca. 75% of average salary in W-Germany.
