Summary
[edit]| Description |
Deutsch: Plattenspieler Ultraphone der Firma Deutsche Ultraphon AG. Das Gerät hat doppelte Schallöffnungen, und wurde erstmalig 1925 von H.J. Küchenmeister im Berliner Hotel Esplanade der Weltöffentlichkeit vorgeführt. Hier wird mit zwei aneinander gekoppelten Tonabnehmern in kurzem Abstand dieselbe Schallrille abtastet. Dadurch entsteht eine künstliche Zeitdifferenz von etwa 1/100 Sekunde, die einen Raumklang vorgetäuscht. |
