Das (US) AUDIO "magazine" von 1947 bis zum Jahr 2000

Das amerikanische "AUDIO magazine" verwirrt uns Deutsche durch die Namensgleichheit mit dem deutschen Hifi-Magazin "AUDIO". Doch das amerikanische "AUDIO magazine" gab es schon Jahrzehnte früher. "AUDIO" zusammen mit "High-Fidelity" und "Stereo Review" gibt uns einen wunderbaren Einblick in den größten Hifi-Markt der Welt.
Ab 1959 sind die gedruckten Ausgaben der US-AUDIO eingescannt. Wir blicken auf etwa 240 Milionen Einwohner - auf 3 Zeitzonen verteilt - und das spiegelt einen Markt wieder, auf dem die eigentliche Hifi-Geschichte geschrieben wurde. Ein Blick in die edlen Wohn- zimmer der oberen 100.000 (= Hunderttausend !! - also nicht unserer "oberen Zehntausend") kommt immer wieder vor. - Auch ein historischer (Ein-) Blick auf und in die alten US-Gebäude, die damaligen US-Studios und die lustigen amerikanischen Büros und Werkstätten der US-Sender und Hersteller ist für uns historisch erhellend und erfreulich informativ.

COVER ILLUSTRATION

The ingenious arrangement of control facilities and studios of the broadcasting station recently completed for KOMO by "The Austin Company" is shown in this view of the master control room. The engineer can see into two 2-way control booths which serve three small studios on the left. He can control broadcasts from the console and his constant visual contact with the operations control center through window on the right. Photo courtesy of The Austin Co.

Erstmalig auf einer AUDIO Coverseite von 1948 sieht man den Amerikaner Jack Mullin mit den neuen AMPEX 200A Bandmaschinen in einem Studio stehen. Ofensichtlich war es gar nicht opprtun, Mullin mit den beiden deutschen AEG K4 Magnetophons zu zeigen, die er in den USA wieder zusammengebaut und mit HF Tehnik nachgerüstet hatte. - Doch so manche von Ampex und Mullin gepflegte Legende löst sich so langsam auf. An der Westküste wurde bereits im November 1945 die gesamt deutsche Magnetophon Palette erstaunlich exakt beschrieben und 1946 den interessierten Fachleuten im US-Wirtschaftministerium vorgeführt.
