The Electrical Era (1 gen 1925 anni – 1 gen 1945 anni)

Descrizione:

The 'second wave' of sound recording history was ushered in by the introduction of Western Electric's integrated system of electrical microphones, electronic signal amplifiers and electromechanical recorders, which was adopted by major US record labels in 1925. Sound recording now became a hybrid process. sound could now be captured, amplified, filtered and balanced electronically, and the disc-cutting head was now electrically powered, but the actual recording process remained essentially mechanical.
