Instrument Amplifiers
An instrument amplifier is an electronic amplifier that converts the often barely audible or purely electronic signal of a musical instrument into a larger electronic signal to feed to a loudspeaker. An instrument amplifier is used with musical instruments such as an electric guitar, an electric bass, electric organ, electric piano, synthesizers and drum machine to convert the signal from the pickup (with guitars and other string instruments and some keyboards) or other sound source (e.g, a synthesizer's signal) into an electronic signal that has enough power, produced by a power amplifier, to drive one or more loudspeaker that can be heard by the performers and audience. Combination (combo) amplifiers include a preamplifier, a power amplifier, tone controls, and one or more speakers in a cabinet, a housing or box usually made of wood. Instrument amplifiers for some instruments are also available without an internal speaker; these amplifiers, called ''heads'', must plug int ...

Reverb
In acoustics, reverberation (commonly shortened to reverb) is a persistence of sound after it is produced. It is often created when a sound is reflected on surfaces, causing multiple reflections that build up and then decay as the sound is absorbed by the surfaces of objects in the space – which could include furniture, people, and air. This is most noticeable when the sound source stops but the reflections continue, their amplitude decreasing, until zero is reached. Reverberation is frequency dependent: the length of the decay, or reverberation time, receives special consideration in the architectural design of spaces which need to have specific reverberation times to achieve optimum performance for their intended activity. In comparison to a distinct echo, that is detectable at a minimum of 50 to 100 ms after the previous sound, reverberation is the occurrence of reflections that arrive in a sequence of less than approximately 50 ms. As time passes, the amplitude ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pick Up (music Technology)
A pickup is an electronic device that converts energy from one form to another that captures or senses mechanical vibrations produced by electric instrument, musical instruments, particularly stringed instruments such as the electric guitar, and converts these to an electrical signal that is instrument amplifier, amplified using an instrument amplifier to produce musical sounds through a loudspeaker in a speaker enclosure. The signal from a pickup can also be sound recording, recorded directly. The first electrical string instrument with pickups, the "Frying Pan (guitar), Frying Pan" slide guitar, was created by George Beauchamp and Adolph Rickenbacker around 1931. Most electric guitars and electric basses use Magnet, magnetic pickups. Acoustic guitars, upright basses and fiddles often use a piezoelectric, piezo electric pickup. Magnetic pickups A typical magnetic pickup is a transducer (specifically a variable reluctance sensor) that consists of one or more permanent magnets ...

Public Address System
A public address system (or PA system) is an electronic system comprising microphones, amplifiers, loudspeakers, and related equipment. It increases the apparent volume (loudness) of a human voice, musical instrument, or other acoustic sound source or recorded sound or music. PA systems are used in any public venue that requires that an announcer, performer, etc. be sufficiently audible at a distance or over a large area. Typical applications include sports stadiums, public transportation vehicles and facilities, and live or recorded music venues and events. A PA system may include multiple microphones or other sound sources, a mixing console to combine and modify multiple sources, and multiple amplifiers and loudspeakers for louder volume or wider distribution. Simple PA systems are often used in small venues such as school auditoriums, churches, and small bars. PA systems with many speakers are widely used to make announcements in public, institutional and commercial buildings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AV Receiver
An audio/video receiver (AVR) or a stereo receiver is a consumer electronics component used in a home theater, home audio, or hi-fi system. Its purpose is to receive audio and video signals from a number of sources, and to process them and provide power amplifiers to drive loudspeakers, and/or route the video to displays such as a television, computer monitor, monitor or video projector. Inputs may come from a tuner (radio), TV, FM, or AM tuner, satellite receiver, DVD players, Blu-ray Disc, Blu-ray Disc players, VCRs or video game consoles, among others. The AVR source selection and settings such as volume, are typically set by a remote controller. History A "radio receiver, receiver" in its most basic form is an amplifier, typically at least a two-channel stereo model, that has a built-in radio tuner. Over time, features were integrated that would otherwise require separate pieces of equipment, such as preamplifiers, equalizers, and multiple power amplifiers. As home enterta ...

Marshall Amplifier
Marshall Amplification is a British company that designs and manufactures music amplifiers, speaker cabinets, and effects pedals. Founded in London in 1962 by shop owner and drummer Jim Marshall, the company is based in Bletchley, Milton Keynes, England. The company first began making amplifiers to provide an alternative to expensive, American-made Fender amps, releasing their first model, the Bassman-inspired JTM45, in 1963. Following complaints over limitations in amp volume and tone from visitors to Jim Marshall's drum shop, notably Pete Townshend, guitarist for The Who, Marshall began developing louder, 100-watt amplifiers. These early amps were characterized in part by their Plexiglass control plates, leading to models such as the 1959 Super Lead (released in 1965) being popularly known as "Plexis." Their adoption by guitarists like Townshend, Jimi Hendrix, Eric Clapton, and Jimmy Page helped establish the brand's legacy. Further development led to the JCM800 ser ...

Country Music
Country (also called country and western) is a popular music, music genre originating in the southern regions of the United States, both the American South and American southwest, the Southwest. First produced in the 1920s, country music is primarily focused on singing Narrative, stories about Working class in the United States, working-class and blue-collar worker, blue-collar American life. Country music is known for its ballads and dance tunes (i.e., "Honky-tonk#Music, honky-tonk music") with simple form, folk lyrics, and harmonies generally accompanied by instruments such as banjos, fiddles, harmonicas, and many types of guitar (including acoustic guitar, acoustic, electric guitar, electric, steel guitar, steel, and resonator guitar, resonator guitars). Though it is primarily rooted in various forms of American folk music, such as old-time music and Appalachian music, many other traditions, including African-American, Music of Mexico, Mexican, Music of Ireland, Irish, and ...

Blues
Blues is a music genre and musical form that originated among African Americans in the Deep South of the United States around the 1860s. Blues has incorporated spiritual (music), spirituals, work songs, field hollers, Ring shout, shouts, chants, and rhymed simple narrative ballad (music), ballads from the African-American culture. The blues form is ubiquitous in jazz, rhythm and blues, and rock and roll, and is characterized by the Call and response (music), call-and-response pattern, the blues scale, and specific chord progressions, of which the twelve-bar blues is the most common. Blue notes (or "worried notes"), usually thirds, fifths or sevenths flattened in Pitch (music), pitch, are also an essential part of the sound. Blues shuffle note, shuffles or walking bass reinforce the trance-like rhythm and form a repetitive effect known as the groove (popular music), groove. Blues music is characterized by its lyrics, Bassline, bass lines, and Instrumentation (music), instrumen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fender Bassman
The Fender Bassman is a series of bass amplifiers introduced by Fender during 1952. Initially intended to amplify bass guitars, musicians used the 5B6 Bassman to amplify other instruments, including electric guitars, harmonicas, and pedal steel guitars. Besides being a popular and important amplifier in its own right, the Bassman also became the foundation on which Marshall and other companies built their high-gain tube amplifiers. History The 5B6 Bassman During 1952, the Fender 5B6 Bassman amplifier was introduced as a combo amplifier cabinet that included the amplifier chassis combined with one 15" speaker. The 1952–1954 5B6 Bassman amplifiers had two 6SC7 or 6SL7GT pre-amp tubes, two 5881 power tubes and a single 5U4G rectifier tube. It was designed to generate 26 watts at an 8-ohm impedance load, and offered a cathode-based bias. From 1952 through the spring of 1954, Fender produced approximately 660 model 5B6 Bassman amplifiers (serial numbers #0001–0660). The earlie ...

Fender Tweed
Fender tweed is a generic name used for the Fender Amplifiers, guitar amplifiers made by the American company Fender Musical Instruments Corporation, Fender between 1948 and 1960. The amplifiers are named for the cloth covering, which consists of varnished cotton twill, incorrectly called Tweed (cloth), tweed because of its feel and appearance. They are praised for their sound, their circuitry being considered "hallowed ground". Fender generally stopped using the twill covering in 1960, exceptions being the Fender Harvard, Harvard which continued to be covered in twill until 1963, and the Fender Champ, Champ until 1964. In 1953, Fender introduced the "wide panel" construction, where the top and bottom panels are wider than the side panels. In the later "narrow panels", introduced in 1955, all panels have approximately the same size. Later amplifiers used tolex for the covering. Beginning in 1990, Fender began to utilize the tweed covering once again, starting with the '59 Bassman ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keyboard Amp
A keyboard amplifier is a powered electronic amplifier and loudspeaker in a speaker cabinet used for the amplification of electronic keyboard instruments. Keyboard amplifiers are distinct from other types of amplification systems such as guitar amplifiers due to the particular challenges associated with making keyboards sound louder on stage; namely, to provide solid low-frequency sound reproduction for the deep basslines that keyboards can play ''and'' crisp high-frequency sound for the high-register notes. Another difference between keyboard amplifiers and guitar/bass amplifiers is that keyboard amps are usually designed with a relatively flat frequency response and low distortion. In contrast, many guitar and bass amp designers purposely make their amplifiers modify the frequency response, typically to "roll-off" very high frequencies, and most rock and blues guitar amps, and since the 1980s and 1990s, even many bass amps are designed to add distortion or overdrive to the i ...
