Turntablism en 1910 – GAUMONT CHRONOPHONE SYSTEM

Como se suele decir, está todo inventado y para muestra, este sistema para “DJ’in” de principios de siglo pasado…se trata del Gaumont Chronophone System y consiste en una gramola doble con crossfader mecánico y amplificación mediante compresión de aire, una maravilla de la tecnología…¡¡¡

Como se puede observar el sistema se compone de un motor para los dos platos (ultima imagen) y un sistema de mangueras y válvulas para captar y enviar la señal de audio la las trompetas…mediante una válvula el operador podía cambiar entre uno y otro plato, primitivo, pero efectivo…Old Skool Scratching…¡¡¡

Aunque el sistema fue ideado para sincronizar el audio de las películas de la época, nada impide su uso a nivel DJ, pero hay que tener en cuenta el sistema de agujas, como se puede observar en las siguientes imágenes, yo no me atrevería a colocar uno de mis vinilos en este aparato…

In 1903 French engineer Leon Gaumont was granted patents for loudspeaker systems to go with his sound on disc talking films, which used one of Berliner’s Gramophones…In 1910 Gaumont demonstrated his Chronophone system, which synchronised sound and film, at the Gaumont Palace in Paris. The compressed-air amplifier, whiuch he called the Eglephone, was just a part of the whole system. The volume was enough for an audience of 4000. Initially the longest moving picture that could be made with synchronised sound was only 200ft, due to the limited playing time of the Gramophone record. (Projection was at 16 frames per second) Gaumont surmounted this problem by having two gramophone platters; a deft operator could switch between them to give a more or less continuous soundtrack.

Note the twin gramophones, driven from a common electric motor between them. An air hose goes to each valvebox from the control valve just under the air pressure gauge; I suspect that this control valve allowed the operator to crossfade between the two gramophones. DJ in the house!


Below this, there is a light-coloured metal manifold which connects the the gramophone output pipes to the two horns. Quite how the record arms are pivoted so they can follow the track on the disc is a bit unclear, but there appears to be some sort of ball joint where they enter the manifold.
