LS3 5A
The LS3/5A (each element pronounced separately, without the stroke) is a small studio monitor loudspeaker originated by the BBC for use by outside broadcast vans to ensure quality of their broadcasts. The speaker concept set out transparent and natural sound as the goal, and the achievement of the end result is widely acknowledged. The BBC granted licences to a small number of British firms, who first manufactured the product in 1975. The product underwent a change in 1987 due to consistency issues in manufacturing, and again in around 2003 when original parts from KEF (manufacturer), KEF ran out. Upwards of 60,000 pairs of the speaker have been sold. Reviewers have recognised its enormous importance as a bookshelf design. History The LS3/5A is a commercially produced loudspeaker driven by the need of the BBC to monitor and assess broadcast programme quality. It was derived from the LS3/5, which was conceived and developed by the BBC Engineering Department in the early 1970s, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inductor
An inductor, also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. An inductor typically consists of an insulated wire wound into a coil. When the current flowing through the coil changes, the time-varying magnetic field induces an electromotive force (''emf'') (voltage) in the conductor, described by Faraday's law of induction. According to Lenz's law, the induced voltage has a polarity (direction) which opposes the change in current that created it. As a result, inductors oppose any changes in current through them. An inductor is characterized by its inductance, which is the ratio of the voltage to the rate of change of current. In the International System of Units (SI), the unit of inductance is the henry (H) named for 19th century American scientist Joseph Henry. In the measurement of magnetic circuits, it is equivalent to . Inductors have values that typical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linn Products
Linn Products is an engineering company that manufactures hi-fi and audio equipment. Founded by Ivor Tiefenbrun in Glasgow, Scotland, in 1973, the company is best known as the manufacturer of the Linn Sondek LP12 turntable. From 2007 Linn was one of the first audio manufacturers to introduce digital music streaming using the home network and internet. This has become the focus of the company's strategy leading to audio systems to support digital music playback of 24bit/192 kHz studio master quality recordings using a digital stream over a home network. Linn Records was the first to sell DRM-free 24-bit Studio Master quality tracks downloaded over the internet. This network approach was extended in 2013 with the introduction of the Linn Exakt technology to retain the 24-bit lossless signal in the digital domain to the active crossover. In late 2014 Linn announced the integration of Tidal (service), TIDAL's lossless music streaming service into Linn DS digital players enabl ...

BBC Research & Development
BBC Research & Development is the technical research department of the BBC. Function It has responsibility for researching and developing advanced and emerging media technologies for the benefit of the corporation, and wider UK and European media industries, and is also the technical design authority for a number of major technical infrastructure transformation projects for the UK broadcasting industry. Structure BBC R&D is part of the wider BBC Design & Engineering, and is led by Jatin Aythora, Director, Research & Development. In 2011, the North Lab moved into MediaCityUK in Salford along with several other departments of the BBC, whilst the South Lab remained in White City in London. History In April 1930 the Development section of the BBC became the Research Department. The department as it stands today was formed in 1993 from the merger of the BBC Designs Department and the BBC Research Department. From 2006 to 2008 it was known as Research and Innovation but has sin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bi-wiring
Bi-wiring is a means of connecting a :loudspeaker to an audio :amplifier, primarily used in hi-fi systems. Normally, there is one pair of connectors on a loudspeaker and a single cable (two conductors) runs from the amplifier output to the terminals at the loudspeaker housing. From this point, connections are made to the loudspeaker drivers – usually through audio crossover networks. In bi-wiring, each loudspeaker has two pairs of connectors and two cables are run from the same amplifier output to the speaker cabinet – one for the high frequency or tweeter driver and one for the low-frequency driver (through two separated crossover filters). The purported advantage of this split is that it "reduces magnetic interaction in the cable, resulting in better sound".Harley, Robert (17 November 2008Home-Theater Audio: Equipment report''The Absolute Sound''. However, technical analysis suggests that while bi-wired arrangements may be expected to have differences from single wired ...

The Absolute Sound
''The Absolute Sound'' (TAS) is an American audiophile magazine which reviews high-end audio equipment, along with recordings and comments on various music-related subjects. History ''The Absolute Sound'' was founded in 1973 by Harry Pearson, who was its editor-in-chief and publisher. In the early years, TAS was a quarterly, digest-sized magazine and accepted no advertisements. During the 1970s and 1980s, TAS (along with Stereophile) was influential in the audiophile industry. Pearson is credited as being the most important figure in the rise of High-End audio. Until the mid- to late 1990s, Pearson owned and directed all rights to TAS. The magazine was published by Pearson Publishing Inc., which also published a sister high-end video review magazine published quarterly called ''The Perfect Vision''. Pearson remained the chairman of its editorial advisory board until 2006 and regularly contributed a feature entitled HP's Workshop until his departure in 2012. The magazine is n ...

Spendor
Spendor is a British loudspeaker manufacturing company founded in 1969 by audio engineer Spencer Hughes (1924–1983) and his wife Dorothy. It is located in East Sussex. (PDF, 3,2 MB) The name was derived from the first names of both. Research in the 1960s Spencer Hughes worked in an investigation team of the BBC research department in the 1960s. Though journeying into Television, this was a time period when the BBC's licence budget meant the main transmission output was still radio, the imperative behind that of a BBC licensed loudspeaker was that (within the physical confines of a small bookshelf speaker) the principle objective of the loudspeaker was to reproduce an output audio signal with an acoustic fidelity to an original radio presenter's voice; principally within the entire spoken vocal range. To this end the resultant, and historically important ''BBC LS35A'' loudspeaker hit the retail market, the optional license meant any manufacture could procure a license to produce ...
