Phonograph
A phonograph, in its later forms also called a gramophone (as a trademark since 1887, as a generic name in the UK since 1910) or since the 1940s called a record player, or more recently a turntable, is a device for the mechanical and analogue recording and reproduction of sound. The sound vibration waveforms are recorded as corresponding physical deviations of a spiral groove engraved, etched, incised, or impressed into the surface of a rotating cylinder or disc, called a "record". To recreate the sound, the surface is similarly rotated while a playback stylus traces the groove and is therefore vibrated by it, very faintly reproducing the recorded sound. In early acoustic phonographs, the stylus vibrated a diaphragm which produced sound waves which were coupled to the open air through a flaring horn, or directly to the listener's ears through stethoscope-type earphones. The phonograph was invented in 1877 by Thomas Edison. Alexander Graham Bell's Volta Laboratory made s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roksan Xerxes
The Roksan Xerxes transcription turntable (often shortened to Xerxes) is a record player named after the Persian king Xerxes I and produced by London-based Roksan Audio. Designed by Roksan co-founder, Touraj Moghaddam, the Xerxes is a belt-driven turntable with a solid plinth. Launched in 1985, the sound quality of the product positioned it as a strong competitor against the established industry leader, the Linn Sondek LP12. Many reviewers use the Xerxes as a reference turntable. The production version of the Xerxes is called "Xerxes.20plus", a reference to the 20th anniversary of the launch, in 2005. History Before Touraj Moghaddam founded Roksan, he had become dissatisfied with the state of the audio arts when he heard his little television set reproduce Thelonious Monk in a more musically satisfying way than his high-end Linn/Naim tri-amped audio system. Through experimentation, he deduced that the existing turntable design failed because the cartridge was not being held s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goods Manufactured In Scotland
In economics, goods are items that satisfy human wants and provide utility, for example, to a consumer making a purchase of a satisfying product. A common distinction is made between goods which are transferable, and services, which are not transferable. A good is an "economic good" if it is useful to people but scarce in relation to its demand so that human effort is required to obtain it.Samuelson, P. Anthony., Samuelson, W. (1980). Economics. 11th ed. / New York: McGraw-Hill. In contrast, free goods, such as air, are naturally in abundant supply and need no conscious effort to obtain them. Private goods are things owned by people, such as televisions, living room furniture, wallets, cellular telephones, almost anything owned or used on a daily basis that is not food-related. A consumer good or "final good" is any item that is ultimately consumed, rather than used in the production of another good. For example, a microwave oven or a bicycle that is sold to a consumer is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Audiovisual Introductions In 1972
Audiovisual (AV) is electronic media possessing both a sound and a visual component, such as slide-tape presentations, films, television programs, corporate conferencing, church services, and live theater productions. Audiovisual service providers frequently offer web streaming, video conferencing, and live broadcast services. Computer-based audiovisual equipment is often used in education, with many schools and universities installing projection equipment and using interactive whiteboard technology. Components Aside from equipment installation, two significant elements of audiovisual are wiring and system control. If either of these components are faulty or missing, the system may not demonstrate optimal performance. Wiring is a skill that not only requires proper cable rating selection based on a number of factors, including distance to the main rack, frequency and fire codes, but wires should also be out of sight, behind the walls and in the ceiling, when possible.

Masonite
Masonite is a type of hardboard, a kind of engineered wood, which is made of steam-cooked and pressure-molded wood fibers in a process patented by William H. Mason. It is also called Quartrboard, Isorel, hernit, karlit, torex, treetex, and pressboard. History A product resembling masonite (hardboard) was first made in England in 1898 by hot-pressing waste paper.Akers, 1966, p. x Masonite was patented in 1924 in Laurel, Mississippi, by William H. Mason, who was a friend and protégé of Thomas Edison. Mass production started in 1929. In the 1930s and 1940s, Masonite was used for applications including doors, roofing, walls, desktops, and canoes. It was sometimes used for house siding. Similar "tempered hardboard" is now a generic product made by many forest product companies. The Masonite Corporation entered the door business as a supplier of facings in 1972, and was purchased in 2001 by Premdor Corporation, a door maker, from its former parent International Paper.

Medium-density Fibreboard
Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibres, often in a defibrator, combining it with wax and a resin binder, and forming it into panels by applying high temperature and pressure. MDF is generally denser than plywood. It is made up of separated fibres but can be used as a building material similar in application to plywood. It is stronger and denser than particle board. The name derives from the distinction in densities of fibreboard. Large-scale production of MDF began in the 1980s, in both North America and Europe. Physical properties Over time, the term "MDF" has become a generic name for any dry-process fibre board. MDF is typically made up of 82% wood fibre, 9% urea-formaldehyde resin glue, 8% water, and 1% paraffin wax. The density is typically between . The range of density and classification as light-, standard-, or high-density board is a misnomer and confusing. The density of the b ...

Sine Wave
A sine wave, sinusoidal wave, or just sinusoid is a curve, mathematical curve defined in terms of the ''sine'' trigonometric function, of which it is the graph of a function, graph. It is a type of continuous wave and also a Smoothness, smooth periodic function. It occurs often in mathematics, as well as in physics, engineering, signal processing and many other fields. Formulation Its most basic form as a function of time (''t'') is: y(t) = A\sin(2 \pi f t + \varphi) = A\sin(\omega t + \varphi) where: * ''A'', ''amplitude'', the peak deviation of the function from zero. * ''f'', ''frequency, ordinary frequency'', the ''Real number, number'' of oscillations (cycles) that occur each second of time. * ''ω'' = 2''f'', ''angular frequency'', the rate of change of the function argument in units of radians per second. * \varphi, ''phase (waves), phase'', specifies (in radians) where in its cycle the oscillation is at ''t'' = 0. When \varphi is non-zero, the entire waveform appears to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Highland Park Distillery
Highland Park distillery is the second northernmost single malt Scotch whisky distillery in Scotland ( Kimbland Distillery on Sanday being 22 miles further north), located in Kirkwall on the Orkney Islands. History Highland Park distillery was founded by Magnus Eunson, a butcher and church officer by day and illicit distiller and whisky smuggler by night. In 1798 he was caught illegally distilling whisky on the site. In 1826, nearly 30 years later, Highland Park received an official licence to distill whisky. The name of the distillery does not refer to the Scottish Highlands, but rather to the fact that the distillery was founded on an area called 'High Park' distinguished from a lower area nearby. Production The distilling process at Highland Park is the same as that used at other distilleries. Highland Park uses the local peat, which contains a higher proportion of heather than many other peats. The whisky is aged in sherry casks made of either American or European oak, p ...

Printed Circuit Board
A printed circuit board (PCB; also printed wiring board or PWB) is a medium used in Electrical engineering, electrical and electronic engineering to connect electronic components to one another in a controlled manner. It takes the form of a Lamination, laminated sandwich structure of conductive and insulating layers: each of the conductive layers is designed with an artwork pattern of traces, planes and other features (similar to wires on a flat surface) Chemical milling, etched from one or more sheet layers of copper Lamination, laminated onto and/or between sheet layers of a Insulator (electricity), non-conductive substrate. Electrical components may be fixed to conductive pads on the outer layers in the shape designed to accept the component's terminals, generally by means of soldering, to both electrically connect and mechanically fasten them to it. Another manufacturing process adds Via (electronics), vias: plated-through holes that allow interconnections between layers. ...

Pink Triangle (audio Manufacturer)
Pink Triangle Products Ltd was a British audio manufacturer specialising in high end turntables. It was founded in London in 1979 by Neal Jackson and Arthur Khoubesserian. Jackson chose the name 'Pink Triangle' after the symbol used to identify homosexuals in Nazi concentration camps (both Jackson and Khoubesserian are gay). Initial manufacturing took place on an industrial estate in Maidstone Road, Sidcup, Kent, and later at Lomond Grove, Camberwell, London. The company closed in 2003. History Phonograph turntables Very few of the company's first product, referred to as the Pink Triangle Original turntable, were produced. This product and some of the later models included some then very innovative design features. It had an 'aerolam' (a very light and stiff aluminium honeycomb structure developed for and first used by the aircraft industry) sub-chassis that rigidly coupled the platter/bearing assembly with the tone-arm while being low in mass, for low storage of vibrational ...
