Soooo is LSA1 is the original design name and brand or the BBC design was branded differently?
Yes. LSA 1 is the BBC project name. Those monitors were made by Goodmans, and especially KEF and and Rogers. The BBC engineers at the time who went on to form their own companies, like Spendor, Harbeth and Castle, also were allowed to make them.
The British taxpayers, and everybody who has to by a license at the post office to watch or listen to the BBC were very generous back then.
Other significant projects by the BBC, were the development with 3M of the worlds first digital tape recorder. It was DASH (Digital Audio Stationary Head).
The really big project that broke the bank, was the development of the worlds first digital mixing console with Rupert Neve. This was in the early eighties. It was first used for a Christmas Eve broadcast of a Festival of Nine Lessons and Carols from Kings College Cambridge. This broadcast is Britain's annual Christmas gift to the world. It is the most listened to broadcast world wide.
When Margaret Thatcher found out how much this cost, and that no patents were applied for then, or ever, she rapidly moved to reduce funds to BBC engineering.
The fact she was furious was to put it mildly. All BBC engineering was well published for the benefit of mankind until then.
We are still benefiting from a lot of that pioneering work today.
Rupert Neve went broke on the project and had to be bought by Siemens. A warning as to the real costs of progress.
