The highlight of the display is the Western Electric mechanical amplifier shown above (left), the first known device for amplifying audio signals. Produced in the mid part of the first decade of 1900, the device was used to amplify sound in early telephones.
A second, equally compelling artifact is what is believed to be the world’s first tube amplifier, which was used for long-distance telephone transmission in the early part of the 19th century. The amplifier was patented by Austrian physicist Robert Von Lieben and manufactured in Berlin in 1912 by Telefunken for Gesellschaft Fur Drahlose Telegraphie.
The display will also include “innumerable historical artifacts documenting the birth and genesis of our sound and recording industries,” according to library/museum director Louis Manno.
The historic gear will be on display at booth 946 during the exhibition part of the show, which runs October 17-19.
