Founded in 1969, SSL has since expanded to its present 15 acre (61,000 m²) science park in Oxfordshire, England. The company invents, designs and manufactures technology for the manipulation of sound and the production and delivery of video. SSL employs over 160 people worldwide and has regional offices in Los Angeles, Milan, New York, Paris and Tokyo, with additional support provided by an international network of distributors. One of the first SSL consoles (in fact the first in the UK, and only the second console sold) was a 4000B installed at The Townhouse Studios on Goldhawk Road in London. Possibly the earliest 4000E console was at RG Jones in London, closely followed by Eden Studios and Sarm Studios.
