Early BBC broadcasting studio
Numéro d’image : 12655707
| British Broadcasting Company Studio at No. 2 Savoy Hill, central London in 1923 at the beginning of the UK broadcasting service. The walls and ceiling were draped with fabric to damp reverberation and overcome the poor frequency characteristics of the system of microphone with the crystal set receivers and headphones of the listeners. In the centre is the moving-coil Marconi-Sykes Magnetophone encased in a Faraday cage. The resultant short reverberation time was ideal for speech, but not for the performance of music with its lack of bass caused by the loss of low frequencies. The audio signals were amplified and sent by telephone land line to Marconi House in the Strand to be transmitted from a 1 kilowatt medium wave AM transmitter having a radio frequency of 369 meters, London call sign 2LO. This began the research and development of studio acoustics and broadcasting technologies. | |
