Stage Monitors
A stage monitor system is a set of performer-facing loudspeakers called monitor speakers, stage monitors, floor monitors, wedges, or foldbacks on stage (theatre), stage during live music performances in which a sound reinforcement system is used to amplify a performance for the audience. The monitor system allows musicians to hear themselves and fellow band members clearly. The sound at popular music and rock music concerts is amplified with power amplifiers through a sound reinforcement system. With the exception of the smallest venues, such as coffeehouses, most mid- to large-sized venues use two sound systems. The main or front of house, front-of-house (FOH) system amplifies the onstage sounds for the main audience. The monitor system is driven by a Live sound mixing, mix separate from the front-of-house system. This mix typically highlights the vocals and acoustic instruments so they can be heard over the Electronic musical instrument, electronic instruments and drums. Mon ...

12andbullet
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lead Singer
The lead vocalist in popular music is typically the member of a group or band whose voice is the most prominent melody in a performance where multiple voices may be heard. The lead singer sets their voice against the accompaniment parts of the ensemble as the dominant sound. In vocal group performances, notably in soul and gospel music, and early rock and roll, the lead singer takes the main vocal melody, with a chorus or harmony vocals provided by other band members as backing vocalists. Lead vocalists typically incorporate some movement or gestures into their performance, and some may participate in dance routines during the show, particularly in pop music. Some lead vocalists also play an instrument during the show, either in an accompaniment role (such as strumming a guitar part), or playing a lead instrument/instrumental solo role when they are not singing (as in the case of lead singer-guitar virtuoso Jimi Hendrix). The lead singer also typically guides the vocal ensembl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bill Graham Civic Auditorium
The Bill Graham Civic Auditorium (formerly San Francisco Civic Auditorium) is a multi-purpose arena in San Francisco, California, named after promoter Bill Graham. The arena holds 8,500 people. About the venue The auditorium was designed by renowned Bay Area architects John Galen Howard, Frederick Herman Meyer and John W. Reid Jr. and built in 1915 as part of the Panama–Pacific International Exposition. The auditorium hosted the 1920 Democratic National Convention, the San Francisco Opera from 1923 to 1932 and again for the 1996 season, the National AAU boxing trials in 1948, and it was the home of the San Francisco Warriors of the National Basketball Association from 1964 to 1967. An underground expansion, named Brooks Hall, was completed in 1958 under the Civic Center Plaza, immediately north of the Civic Auditorium. The famous Mother of All Demos was presented here during the 1968 Fall Joint Computer Conference, and the World Cyber Games 2004 were also held here. In 1992 ...

Judy Garland
Judy Garland (born Frances Ethel Gumm; June 10, 1922June 22, 1969) was an American actress and singer. While critically acclaimed for many different roles throughout her career, she is widely known for playing the part of Dorothy Gale in '' The Wizard of Oz'' (1939). She attained international stardom as an actress in both musical and dramatic roles, as a recording artist and on the concert stage. Renowned for her versatility, she received an Academy Juvenile Award, a Golden Globe Award and a Special Tony Award. Garland was the first woman to win the Grammy Award for Album of the Year, which she won for her 1961 live recording titled ''Judy at Carnegie Hall''. Garland began performing as a child with her two older sisters, in a vaudeville group " The Gumm Sisters" and was later signed to Metro-Goldwyn-Mayer as a teenager. She appeared in more than two dozen films for MGM. Garland was a frequent on-screen partner of both Mickey Rooney and Gene Kelly and regularly collaborated w ...

Hammond Organ
The Hammond organ is an electric organ invented by Laurens Hammond and John M. Hanert and first manufactured in 1935. Multiple models have been produced, most of which use sliding drawbars to vary sounds. Until 1975, Hammond organs generated sound by creating an electric current from rotating a metal tonewheel near an electromagnetic pickup, and then strengthening the signal with an amplifier to drive a speaker cabinet. The organ is commonly used with the Leslie speaker. Around two million Hammond organs have been manufactured. The organ was originally marketed by the Hammond Organ Company to churches as a lower-cost alternative to the wind-driven pipe organ, or instead of a piano. It quickly became popular with professional jazz musicians in organ trios—small groups centered on the Hammond organ. Jazz club owners found that organ trios were cheaper than hiring a big band. Jimmy Smith's use of the Hammond B-3, with its additional harmonic percussion feature, inspired a g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhythm Section
A rhythm section is a group of musicians within a music ensemble or band that provides the underlying rhythm, harmony and pulse of the accompaniment, providing a rhythmic and harmonic reference and "beat" for the rest of the band. The rhythm section is often contrasted with the roles of other musicians in the band, such as the lead guitarist or lead vocals whose primary job is to carry the melody. The core elements of the rhythm section are usually the drum kit and bass. The drums and bass provide the basic pulse and groove of a song. The section is augmented by other instruments such as keyboard instruments and guitars that are used to play the chord progression upon which the song is based. The bass instrument (either double bass or electric bass guitar, or another low-register instrument, such as synth bass, depending on the group and its style of music) plays the low-pitched bassline. The bassline is a musical part that supports the chord progression, typically by playing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subwoofer
A subwoofer (or sub) is a loudspeaker designed to reproduce low-pitched audio frequencies known as bass and sub-bass, lower in frequency than those which can be (optimally) generated by a woofer. The typical frequency range for a subwoofer is about 20–200 Hz for consumer products, below 100 Hz for professional live sound, and below 80 Hz in THX-certified systems. Subwoofers are never used alone, as they are intended to ''augment'' the low-frequency range of loudspeakers that cover the higher frequency bands. While the term "subwoofer" technically only refers to the speaker driver, in common parlance, the term often refers to a subwoofer driver mounted in a speaker enclosure (cabinet), often with a built-in amplifier. Subwoofers are made up of one or more woofers mounted in a loudspeaker enclosure—often made of wood—capable of withstanding air pressure while resisting deformation. Subwoofer enclosures come in a variety of designs, including bass reflex (wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
In-ear Monitor
In-ear monitors (IEMs) are devices used by musicians, audio engineers and audiophiles to listen to music or to hear a personal mix of vocals and stage instrumentation for live performance or recording studio mixing. They are also used by television presenters in order to receive vocal instructions, info, and breaking news announcements from a producer that only the presenter hears. They are often custom fitted for an individual's ears to provide comfort and a high level of noise reduction from ambient surroundings. Their origins as a tool in live music performance can be traced back to the mid-1980s. A stage monitor system is any system that provides a mix of audio sources to a performer on stage. Traditionally, loudspeakers were placed on the stage directed toward the performers. These loudspeakers can have disadvantages. First, floor wedges greatly increase the onstage volume, in some cases to potential hearing damage levels. Second, while floor wedges can be placed in front ...

Reverb
Reverberation (also known as reverb), in acoustics, is a persistence of sound, after a sound is produced. Reverberation is created when a sound or signal is reflected causing numerous reflections to 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 of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PA Systems
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] |
Loudspeaker
A loudspeaker (commonly referred to as a speaker or speaker driver) is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound. A ''speaker system'', also often simply referred to as a "speaker" or "loudspeaker", comprises one or more such speaker ''drivers'', an enclosure, and electrical connections possibly including a crossover network. The speaker driver can be viewed as a linear motor attached to a diaphragm which couples that motor's movement to motion of air, that is, sound. An audio signal, typically from a microphone, recording, or radio broadcast, is amplified electronically to a power level capable of driving that motor in order to reproduce the sound corresponding to the original unamplified electronic signal. This is thus the opposite function to the microphone; indeed the ''dynamic speaker'' driver, by far the most common type, is a linear motor in the same basic configuration as the dynamic microphone which uses such ...
