Neumann U 47
The Neumann is a large-diaphragm condenser microphone. It is one of the most famous studio microphones and was Neumann's first microphone after the Second World War. The original series, manufactured by Georg Neumann GmbH between 1949 and 1965, employed a tube design; early used the capsule, then replaced by the from 1958. Units produced before 1950 were distributed by Telefunken and bear the Telefunken logo. Since Telefunken ceased production of tubes in 1957, the was discontinued in 1965 and followed by the in 1969; it employed the same capsule () and a similar head grille but used solid-state circuitry (discrete op-amps). Intended to recreate the sound of the original , it enjoyed only limited success; however, the , being able to handle high-pressure levels, became popular among recording engineers as a bass drum microphone, and it is also appreciated as a brass, double bass, and guitar amp microphone. Neumann manufactured the between 1969 and 1986 and reissued it i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neumann U47 Tube
Neumann () is a German surname, with its origins in the pre-7th-century (Old English) word '' neowe'' meaning "new", with ''mann'', meaning man. The English form of the name is Newman. Von Neumann is a variant of the name, and alternative spellings include Neuman, Naumann(s), Nauman, Neiman, and Nyeman. Its first recorded uses were Godwin Nieweman in Oxfordshire, England, in 1169, and in Germany, Herman Nyeman of Barth in 1325. It was mostly likely originally used as a nickname for a recent arrival or settler. Its early use in Germany was mainly in West Prussia and Pomerelia. It was also used by the Anglo-Saxons and in France (as Neuman). In Middle High German the word for "new" was '' niuwe'', and in modern German ''neu''. it is the 18th most common surname in Germany. Notable people with the surname are listed below.

Polyvinyl Chloride
Polyvinyl chloride (alternatively: poly(vinyl chloride), colloquial: vinyl or polyvinyl; abbreviated: PVC) is the world's third-most widely produced synthetic polymer of plastic (after polyethylene and polypropylene). About 40 million tons of PVC are produced each year. PVC comes in rigid (sometimes abbreviated as RPVC) and flexible forms. Rigid PVC is used in construction for pipes, doors and windows. It is also used in making plastic bottles, packaging, and bank or membership cards. Adding plasticizers makes PVC softer and more flexible. It is used in plumbing, electrical cable insulation, flooring, signage, phonograph records, inflatable products, and in rubber substitutes. With cotton or linen, it is used in the production of canvas. Polyvinyl chloride is a white, brittle solid. It is soluble in ketones, chlorinated solvents, dimethylformamide, THF and DMAc. Discovery PVC was synthesized in 1872 by German chemist Eugen Baumann after extended investigation and experimenta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Martin
Sir George Henry Martin (3 January 1926 – 8 March 2016) was an English record producer, arranger, composer, conductor, and musician. He was commonly referred to as the "fifth Beatle" because of his extensive involvement in each of the Beatles' original albums. Martin's formal musical expertise and interest in novel recording practices facilitated the group's rudimentary musical education and desire for new musical sounds to record. Most of their orchestral and string arrangements were written by Martin, and he played piano or keyboards on a number of their records. Their collaborations resulted in popular, highly acclaimed records with innovative sounds, such as the 1967 album ''Sgt. Pepper's Lonely Hearts Club Band''—the first rock album to win a Grammy Award for Album of the Year. Martin's career spanned more than sixty years in music, film, television and live performance. Before working with the Beatles and other pop musicians, he produced comedy and novelty records in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microphone
A microphone, colloquially called a mic (), or mike, is a transducer that converts sound into an electrical signal. Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, sound recording, two-way radios, megaphones, and radio and television broadcasting. They are also used in computers and other electronic devices, such as mobile phones, for recording sounds, speech recognition, Voice over IP, VoIP, and other purposes, such as Ultrasonic transducer, ultrasonic sensors or knock sensors. Several types of microphone are used today, which employ different methods to convert the air pressure variations of a sound wave to an electrical signal. The most common are the dynamic microphone, which uses a coil of wire suspended in a magnetic field; the condenser microphone, which uses the vibrating Diaphragm (acoustics), diaphragm as a capacitor ...

Nuvistor
The nuvistor is a type of vacuum tube announced by RCA in 1959. Nuvistors were made to compete with the then-new bipolar junction transistors, and were much smaller than conventional tubes of the day, almost approaching the compactness of early discrete transistor casings. Due to their small size, there was no space to include a vacuum fitting to evacuate the tube; instead, nuvistors were assembled and processed in a vacuum chamber by simple robotic devices. The tube envelope is made of metal, with a ceramic base. Triodes and a few tetrodes and pentodes were made; nuvistor tetrodes were taller than triodes. Nuvistors are among the highest-performing small-signal radio-frequency receiving tubes, largely due to low stray capacitance and inductance due to their small size. They have excellent VHF and UHF performance, and low noise figures, and were widely used throughout the 1960s for low-power applications in television sets (beginning with RCA's "New Vista" line of color set ...

Pentode
A pentode is an electronic device having five electrodes. The term most commonly applies to a three-grid amplifying vacuum tube or thermionic valve that was invented by Gilles Holst and Bernhard D.H. Tellegen in 1926. The pentode (called a ''triple-grid amplifier'' in some literature) was developed from the ''screen-grid tube'' or ''shield-grid tube'' (a type of tetrode tube) by the addition of a grid between the screen grid and the plate. The screen-grid tube was limited in performance as an amplifier due to secondary emission of electrons from the plate. The additional grid is called the ''suppressor grid''. The suppressor grid is usually operated at or near the potential of the cathode and prevents secondary emission electrons from the plate from reaching the screen grid. The addition of the suppressor grid permits much greater output signal amplitude to be obtained from the plate of the pentode in amplifier operation than from the plate of the screen-grid tube at the same plat ...

Vacuum Tube
A vacuum tube, electron tube, thermionic valve (British usage), or tube (North America) is a device that controls electric current flow in a high vacuum between electrodes to which an electric voltage, potential difference has been applied. It takes the form of an evacuated tubular envelope of glass or sometimes metal containing electrodes connected to external connection pins. The type known as a thermionic tube or thermionic valve utilizes thermionic emission of electrons from a hot cathode for fundamental Electronics, electronic functions such as signal amplifier, amplification and current Rectifier, rectification. Non-thermionic types such as vacuum phototubes achieve electron emission through the photoelectric effect, and are used for such purposes as the detection of light and measurement of its intensity. In both types the electrons are accelerated from the cathode to the anode by the electric field in the tube. The first, and simplest, vacuum tube, the diode or Flem ...

PET Film (biaxially Oriented)
BoPET (biaxially oriented polyethylene terephthalate) is a polyester film made from stretched polyethylene terephthalate (PET) and is used for its high tensile strength, chemical stability, dimensional stability (fabric), dimensional stability, Transparency (optics), transparency reflectivity, and electrical insulation. When Metallised film, metallized, it has gas and moisture barrier properties. The film is "biaxially oriented", which means that the polymer chains are oriented parallel to the plane of the film, and therefore oriented over two axes. A variety of companies manufacture boPET and other polyester films under different brand names. In the UK and US, the best-known trade names are Mylar, Melinex, Lumirror and Hostaphan. It was the first biaxially oriented polymer to be manufactured on a mass commercial scale.
