Record Changer
A record changer or autochanger is a device that plays several phonograph records in sequence without user intervention. Record changers first appeared in the late 1920s, and were common until the 1980s. History The record changer with a stepped center spindle design was invented by Eric Waterworth of Hobart, Australia, in 1925. He and his father took it to Sydney, and arranged with a company called Home Recreations to fit it into its forthcoming phonograph, the Salonola. Although this novelty was demonstrated at the 1927 Sydney Royal Easter Show, Home Recreations went into liquidation and the Salonola was never marketed. In 1928, the Waterworths traveled to London, where they sold their patent to the new Symphony Gramophone and Radio Co. Ltd. Eric Waterworth built three prototypes of his invention, one of which was sold to Home Recreations as a model for its proposed Salonola record player as cited above, which is now reportedly in the collection of the Museum of Applied Arts ...

Phonograph Record
A phonograph record (also known as a gramophone record, especially in British English) or a vinyl record (for later varieties only) is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the outside edge and ends near the center of the disc. The stored sound information is made audible by playing the record on a phonograph (or "gramophone", "turntable", or "record player"). Records have been produced in different formats with playing times ranging from a few minutes to around 30 minutes per side. For about half a century, the discs were commonly made from shellac and these records typically ran at a rotational speed of 78 rpm, giving it the nickname "78s" ("seventy-eights"). After the 1940s, "vinyl" records made from polyvinyl chloride (PVC) became standard replacing the old 78s and remain so to this day; they have since been produced in various sizes and speeds, most commonly 7-inch discs pla ...

Birmingham Sound Reproducers
Birmingham Sound Reproducers (BSR) was a 20th-century British manufacturer of record player turntables, reel-to-reel tape recorder mechanisms and, for a time, housewares. History Early years Daniel McLean McDonald (1905–1991) founded Birmingham Sound Reproducers as a private company in 1932 in the West Midlands (region), West Midlands of England. By 1947, the company chiefly manufactured communications sets (intercoms), laboratory test equipment, and sound recording and reproducing instruments including phonographs. Record turntables and related products In the early 1950s, Samuel Margolin began buying Record changer, auto-changing turntables from BSR, using them as the basis of his Dansette record player. Over the next twenty years, Margolin manufactured more than a million of these players, and "Dansette" became a household word in Britain. In 1957, BSR, also known by the name BSR McDonald, became a public company which by 1961 had grown to employ 2,600. It supplied ...

Popular Science
Popular science (also called pop-science or popsci) is an interpretation of science intended for a general audience. While science journalism focuses on recent scientific developments, popular science is more broad ranging. It may be written by professional science journalists or by scientists themselves. It is presented in many forms, including books, film and television documentaries, magazine articles, and web pages. History Before the modern specialization and professionalization of science, there was often little distinction between "science" and "popular science", and works intended to share scientific knowledge with a general reader existed as far back as Greek and Roman antiquity. Without these popular works, much of the scientific knowledge of the era might have been lost. For example, none of the original works of the Greek astronomer Eudoxus (4th century BC) have survived, but his contributions were largely preserved due to the didactic poem '' Phenomena'' writte ...

Crosley Radio Corporation
Powel Crosley Jr. (September 18, 1886 – March 28, 1961) was an American inventor, industrialist, and entrepreneur. He was also a pioneer in radio broadcasting and owner of the Cincinnati Reds major league baseball team. In addition, Crosley's companies manufactured Crosley automobiles and radios, and operated WLW radio station. Crosley, once dubbed "The Henry Ford of Radio," was inducted into the Automotive Hall of Fame in 2010 and the National Radio Hall of Fame in 2013. He and his brother, Lewis M. Crosley, were responsible for many firsts in consumer products and broadcasting. During World War II, Crosley's facilities produced more proximity fuzes than any other U.S. manufacturer and made several production design innovations. Crosley Field, a stadium in Cincinnati, Ohio, was renamed for him, and the street-level main entrance to Great American Ball Park in Cincinnati is named Crosley Terrace in his honor. Crosley's Pinecroft estate home in Cincinnati, and Seagate, his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

CD Changer
A CD player is an electronic device that plays audio compact discs, which are a digital optical disc data storage format. CD players were first sold to consumers in 1982. CDs typically contain recordings of audio material such as music or audiobooks. CD players may be part of home stereo systems, car audio systems, personal computers, or portable CD players such as CD boomboxes. Most CD players produce an output signal via a headphone jack or RCA jacks. To use a CD player in a home stereo system, the user connects an RCA cable from the RCA jacks to a hi-fi (or other amplifier) and loudspeakers for listening to music. To listen to music using a CD player with a headphone output jack, the user plugs headphones or earphones into the headphone jack. Modern units can play audio formats other than the original CD PCM audio coding, such as MP3, AAC and WMA. DJs playing dance music at clubs often use specialized players with an adjustable playback speed to alter the pitch and temp ...

Original Cast Album
A cast recording is a recording of a stage musical that is intended to document the songs as they were performed in the show and experienced by the audience. An original cast recording or OCR, as the name implies, features the voices of the show's original cast. A cast recording featuring the first cast to perform a musical in a particular venue is known, for example, as an "original Broadway cast recording" (OBCR) or an "original London cast recording" (OLCR). Cast recordings are (usually) studio recordings rather than live recordings. The recorded song lyrics and orchestrations are nonetheless identical (or very similar) to those of the songs as performed in the theatre. Like any studio performance, the recording is an idealized rendering, without audible audience reaction. History The British were the first to create cast recordings, and they were also the first to create original London cast recordings of shows that had already opened on Broadway, but had not been recorde ...

Boxed Set
A boxed set or (its US name) box set is a set of items (for example, a compilation of books, musical recordings, films or television programs) traditionally packaged in a box, hence 'boxed', and offered for sale as a single unit. Music Artists and bands with a long and successful career often have anthology or "essential" collections of their music released as box sets. These often include rare and never-before-released tracks. Some box sets collect previously released singles or albums by a music artist, and often collect the complete discography of an artist, such as Pink Floyd's '' Oh, by the Way'' and ''Discovery'' sets. Sometimes bands release expanded versions of their most successful albums, such as Pink Floyd's ''Immersion'' versions of their ''The Dark Side of the Moon'' (1973), '' Wish You Were Here'' (1975) and '' The Wall'' (1979) boxes. Pink Floyd have also released ''The Early Years 1965–1972'' box set, which features mostly unreleased material. Other music box ...

Triple Albums
A double album (or double record) is an audio album that spans two units of the primary medium in which it is sold, typically either records or compact disc. A double album is usually, though not always, released as such because the recording is longer than the capacity of the medium. Recording artists often think of double albums as being a single piece artistically; however, there are exceptions, such as John Lennon's ''Some Time in New York City'' (which consisted of one studio record and one live album packaged together), OutKast's ''Speakerboxxx/The Love Below'' (effectively two solo albums, one by each member of the duo), and Red Hot Chili Peppers' ''Stadium Arcadium'' (which Disc 1 has half of the album and Disc 2 has the other half). Since the advent of the compact disc, albums are sometimes released with a bonus disc featuring additional material as a supplement to the main album, with live tracks, studio out-takes, cut songs, or older unreleased material.

Thorens
Thorens is a formerly Swiss manufacturer of high-end audio equipment. Thorens is historically renowned for the range of phonographs (turntables) the manufacturer produces. In addition to audio playback equipment, Thorens is also a historical manufacturer of harmonicas and has been separately a producer of Swiss-made cigarette lighters, most notably the button actuated "automatic lighter". History In 1883, the Thorens family business was first registered in Sainte-Croix (Ste-Croix), Vaud, Switzerland by Hermann Thorens. An initial producer of musical boxes and clock movements (which they were still producing in the 1950s), as well a cigarette lighters, they started producing Edison-type phonographs in 1903. In 1928, they produced their first electric (motor-drive) record player, and went on to produce a range of audiophile record players in the 1950s and 1960s which are, even today, regarded as high-end audio equipment, and are much sought-after, for example, the belt-drive ...
