Lindos Electronics
Lindos Electronics is a British manufacturer of test equipment for audio quality measurement. History Founded in 1979, by Peter J Skirrow, the business was named after the home where development and manufacture began, as is so often the case, in garage and spare rooms. Since then it has gone on to become a well-known name in audio and broadcasting, supplying test equipment to broadcasters and studios worldwide, and represented at many professional audio exhibitions. The LA1 was the first product to be manufactured, and this was rapidly adopted by engineers at Independent Local Radio stations who needed quality testing equipment to ensure that their studios and transmitters met the IBA Code of Practice before they went on-air. It went on to be widely used by the BBC and other broadcasters and studios worldwide. Manufacture of the LA1 ceased with the introduction of the LA100 but it continues to be a sought-after product second hand. The LA100, launched in 1984, introduced micro ...

Audio Quality Measurement
Audio system measurements are a means of quantifying system performance. These measurements are made for several purposes. Designers take measurements so that they can specify the performance of a piece of equipment. Maintenance engineers make them to ensure equipment is still working to specification, or to ensure that the cumulative defects of an audio path are within limits considered acceptable. Audio system measurements often accommodate psychoacoustic principles to measure the system in a way that relates to human hearing. Subjectivity and frequency weighting Subjectively valid methods came to prominence in consumer audio in the UK and Europe in the 1970s, when the introduction of compact cassette tape, dbx and Dolby noise reduction techniques revealed the unsatisfactory nature of many basic engineering measurements. The specification of weighted CCIR-468 quasi-peak noise, and weighted quasi-peak wow and flutter became particularly widely used and attempts were made ...

Independent Local Radio
Independent Local Radio is the collective name given to commercial radio stations in the United Kingdom. As a result of the buyouts and mergers permitted by the Broadcasting Act 1990, and deregulation resulting from the Communications Act 2003, most commercial stations are now neither independent (although they remain independent from the BBC) nor local. The same name is used for Independent Local Radio in Ireland. History Development of ILR Until the early 1970s, the BBC had a legal monopoly on radio broadcasting in the UK. Despite competition from the commercial Radio Luxembourg and, for a period in the mid-1960s, the off-shore "pirate" broadcasters, it had remained the policy of both major political parties that radio was to remain under the BBC. Upon the election of Edward Heath's government in 1970, this policy changed. It is possible that Heath's victory was partly due to younger voters upset by the UK government closing down the popular pirate radio stations.

Independent Broadcasting Authority
The Independent Broadcasting Authority (IBA) was the regulatory body in the United Kingdom for commercial television (ITV and Channel 4 and limited satellite television regulation – cable television was the responsibility of the Cable Authority) – and commercial and independent radio broadcasts. The IBA came into being when the Sound Broadcasting Act 1972 gave the Independent Television Authority responsibility for organising the new Independent Local Radio (ILR) stations. The Independent Television Commission formally replaced the IBA on 1 January 1991 in regulatory terms; however, the authority itself was not officially dissolved until 2003. The IBA appointed and regulated a number of regional programme TV contractors and local radio contractors, and built and operated the network of transmitters distributing these programmes through its Engineering Division. It established and part-funded a National Broadcasting School to train on-air and engineering staff. Approach The I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waste Electrical And Electronic Equipment Directive
The Waste Electrical and Electronic Equipment Directive (WEEE Directive) is the European Community Directive 2012/19/EU on waste electrical and electronic equipment (WEEE) which, together with the RoHS Directive 2011/65/EU, became European Law in February 2003. The WEEE Directive set collection, recycling and recovery targets for all types of electrical goods, with a minimum rate of per head of population '' per annum'' recovered for recycling by 2009. The RoHS Directive set restrictions upon European manufacturers as to the material content of new electronic equipment placed on the market. The symbol adopted by the European Council to represent waste electrical and electronic equipment comprises a crossed-out wheelie bin with or without a single black line underneath the symbol. The black line indicates that goods have been placed on the market after 2005, when the Directive came into force. Goods without the black line were manufactured between 2002 and 2005.
