Technics SL-10
The Technics SL-10 is a direct-drive, linear tracking automatic turntable, which was produced from 1979 to 1985. Features The SL-10 was the first linear-tracking turntable to feature direct drive, a Technics innovation dating back to 1969 with the SP-10 Mk I. The SL-10, along with its fully programmable stablemate the SL-15, was able to penetrate the consumer electronics market much more effectively than any preceding linear-tracking turntable, and it spawned a wave of imitators throughout the 1980s, along with many derivations by Technics itself. Unlike many of the inexpensive designs that followed it, the SL-10 is cast from aluminum and weighs 6.5 kg (14 lb). Its chassis is the same size as a standard LP jacket, doing away with the large plinth, visible tonearm and general bulk associated with conventional radial-tracking turntables that the public was familiar with up to that point. The SL-10 came equipped with the Technics EPS-310MC moving-coil cartridge. Due to the low o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Technics (brand)
is a Japanese brand name of the Panasonic Corporation for audio equipment. Since 1965 under the brand name, Panasonic has produced a variety of hi-fi products, such as turntables, amplifiers, receivers, tape decks, CD players and speakers for sale in various countries. It was conceived as a line of high-end audio equipment to compete against brands such as Nakamichi. From 2002 onwards products were rebranded as Panasonic except in Japan and CIS countries (such as Russia), where the brand remained in high regard. Panasonic discontinued the brand for most products in October 2010, but it was revived in 2015 with new high-end turntables. The brand is best known for the SL-1200 DJ turntable, an industry standard for decades. History Technics was introduced as a brand name for premium loudspeakers marketed domestically by Matsushita in 1965. The name came to wider prominence with the international sales of direct-drive turntables. The first direct-drive turntable was invente ...

Direct-drive Turntable
A direct-drive turntable is one of the three main phonograph designs currently being produced. The other styles are the belt-drive turntable and the idler-wheel type. Each name is based upon the type of coupling used between the platter of the turntable and the motor. Direct-drive turntables are currently the most popular phonographs, due to their widespread use for turntablism in DJ culture. Panasonic's Technics series were the first direct-drive turntables, and remain the most popular series of turntables. Design In a direct-drive turntable the motor is located directly under the center of the platter and is connected to the platter directly. It is a significant advancement over older belt-drive turntables, which are unsuitable for turntablism, since they have a slow start-up time, and are prone to wear-and-tear and breakage,Brian ColemanThe Technics 1200 — Hammer Of The Gods Medium as the belt would break from backspinning or scratching.

Linear Tracking
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 sev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SL-10 DA26-04M182 4-2 IMG6634p
Stationary Low-Power Reactor Number One, also known as SL-1 or the Argonne Low Power Reactor (ALPR), was a United States Army experimental nuclear reactor in the western United States at the National Reactor Testing Station (NRTS), later the Idaho National Laboratory, west of Idaho Falls, Idaho. It experienced a steam explosion on the night of January 3, 1961, killing all three of its young military operators, and pinning one of them to the ceiling of the facility with a reactor vessel plug. The event is the only reactor accident in U.S. history that resulted in immediate fatalities. The direct cause was the over-withdrawal of the central control rod, responsible for absorbing neutrons in the reactor's core. The accident released about of iodine-131, which was not considered significant due to its location in the remote high desert of eastern Idaho. About of fission products were released into the atmosphere. The facility housing SL-1, located approximately west of Idaho F ...

Decibel
The decibel (symbol: dB) is a relative unit of measurement equal to one tenth of a bel (B). It expresses the ratio of two values of a power or root-power quantity on a logarithmic scale. Two signals whose levels differ by one decibel have a power ratio of 101/10 (approximately ) or root-power ratio of 10 (approximately ). The unit expresses a relative change or an absolute value. In the latter case, the numeric value expresses the ratio of a value to a fixed reference value; when used in this way, the unit symbol is often suffixed with letter codes that indicate the reference value. For example, for the reference value of 1 volt, a common suffix is " V" (e.g., "20 dBV"). Two principal types of scaling of the decibel are in common use. When expressing a power ratio, it is defined as ten times the logarithm in base 10. That is, a change in ''power'' by a factor of 10 corresponds to a 10 dB change in level. When expressing root-power quantities, a change in ''ampl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gimbal
A gimbal is a pivoted support that permits rotation of an object about an axis. A set of three gimbals, one mounted on the other with orthogonal pivot axes, may be used to allow an object mounted on the innermost gimbal to remain independent of the rotation of its support (e.g. vertical in the first animation). For example, on a ship, the gyroscopes, shipboard compasses, stoves, and even drink holders typically use gimbals to keep them upright with respect to the horizon despite the ship's yaw, pitch and roll, pitching and rolling. The gimbal suspension used for mounting compasses and the like is sometimes called a Cardan suspension after Italy, Italian mathematician and physicist Gerolamo Cardano (1501–1576) who described it in detail. However, Cardano did not invent the gimbal, nor did he claim to. The device has been known since antiquity, first described in the 3rd c. BC by Philo of Byzantium, although some modern authors support the view that it may not have a single ide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hertz
The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second. The hertz is an SI derived unit whose expression in terms of SI base units is s−1, meaning that one hertz is the reciprocal of one second. It is named after Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves. Hertz are commonly expressed in multiples: kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz). Some of the unit's most common uses are in the description of periodic waveforms and musical tones, particularly those used in radio- and audio-related applications. It is also used to describe the clock speeds at which computers and other electronics are driven. The units are sometimes also used as a representation of the energy of a photon, via the Planck relation ''E'' = ''hν'', where ''E'' is the photon's energy, ''ν'' is its frequency ...

DJ Equipment
A disc jockey, more commonly abbreviated as DJ, is a person who plays recorded music for an audience. Types of DJs include radio DJs (who host programs on music radio stations), club DJs (who work at a nightclub or music festival), mobile DJs (who are hired to work at public and private events such as weddings, parties, or festivals), and turntablists (who use record players, usually turntables, to manipulate sounds on phonograph records). Originally, the "disc" in "disc jockey" referred to shellac and later vinyl records, but nowadays DJ is used as an all-encompassing term to also describe persons who mix music from other recording media such as cassettes, CDs or digital audio files on a CDJ, controller, or even a laptop. DJs may adopt the title "DJ" in front of their real names, adopted pseudonyms, or stage names. DJs commonly use audio equipment that can play at least two sources of recorded music simultaneously. This enables them to blend tracks together to creat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
