1975 EDITION - 4-CHANNEL EQUIPMENT
Decoders and other

Und hier die letze Rettung für alle, die kein Geld mehr hatten. Das waren die separaten Decoder, die man vor vorhandene Anlagen schalten konnte. Das Abtastsystem bzw. den befähigten Plattenspieler mußte man aber dennoch kaufen. Nur ganz wenige hielten,was sie versprachen und brachten eine erstaunliche Qualität der Hifi-Wiedergabe. Das Quadro-Erlebnis enttäuschte bereits nach ganz kurzer Zeit, egal, welches System man auserwählt hatte.
