XLR Connector
The XLR connector is a type of electrical connector primarily used in professional audio, video, and stage lighting equipment. XLR connectors are cylindical in design, and have three to seven connector pins, and are often employed for analog balanced audio interconnections, AES3 digital audio, portable intercom, DMX512 lighting control, and for low-voltage power supply. XLR connectors are included to the international standard for dimensions, IEC 61076-2-103. The XLR connector is superficially similar to the smaller DIN connector, with which it is physically incompatible. History and manufacturers The XLR connector (also Cannon plug and Cannon connector) was invented by James H. Cannon, founder of the Cannon Electric company, Los Angeles, California. The XLR connector originated from the ''Cannon X'' series of connectors in 1915; by 1950, a latching mechanism was added to the connector, which produced the ''Cannon XL'' model of connector, and by 1955, the female connec ...

Carlsbad, California
Carlsbad is a coastal city in the North County region of San Diego County, California, United States. The city is south of downtown Los Angeles and north of downtown San Diego. As of the 2020 census, the population of the city was 114,746. Carlsbad is a popular tourist destination and home to many businesses in the golf industry. History Carlsbad's history began with the Luiseño people (the Spanish name given to them because of their proximity to Mission San Luis Rey), as well as some Kumeyaay in the La Costa area. Nearly every reliable fresh water creek had at least one native village, including one called Palamai. The site is located just south of today's Buena Vista Lagoon. The first European land exploration of Alta California, the Spanish Portolá expedition of 1769, met native villagers while camped on Buena Vista Creek. Another Luiseño villages within today's city of Carlsbad was a village at the mouth of the San Marcos Creek that the Kumeyaay called 'A ...

Jefferson Airplane
Jefferson Airplane was an American rock band based in San Francisco, California, that became one of the pioneering bands of psychedelic rock. Formed in 1965, the group defined the San Francisco Sound and was the first from the Bay Area to achieve international commercial success. They headlined the Monterey Pop Festival (1967), Woodstock (1969), Altamont Free Concert (1969), and the first Isle of Wight Festival (1968) in England. Their 1967 breakout album '' Surrealistic Pillow'' was one of the most significant recordings of the Summer of Love. Two songs from that album, " Somebody to Love" and " White Rabbit", are among ''Rolling Stone''s "500 Greatest Songs of All Time". The October 1966 to February 1970 lineup of Jefferson Airplane, consisting of Marty Balin (vocals), Paul Kantner (guitar, vocals), Grace Slick (vocals), Jorma Kaukonen (lead guitar, vocals), Jack Casady (bass), and Spencer Dryden (drums), was inducted into the Rock and Roll Hall of Fame in 1996.

Grateful Dead
The Grateful Dead was an American rock band formed in 1965 in Palo Alto, California. The band is known for its eclectic style, which fused elements of rock, folk, country, jazz, bluegrass, blues, rock and roll, gospel, reggae, world music, and psychedelia; for live performances of lengthy instrumental jams that typically incorporated modal and tonal improvisation; and for its devoted fan base, known as "Deadheads". "Their music", writes Lenny Kaye, "touches on ground that most other groups don't even know exists." These various influences were distilled into a diverse and psychedelic whole that made the Grateful Dead "the pioneering Godfathers of the jam band world". The band was ranked 57th by ''Rolling Stone'' magazine in its " The Greatest Artists of All Time" issue. The band was inducted into the Rock and Roll Hall of Fame in 1994 and a recording of their May 8, 1977 performance at Cornell University's Barton Hall was added to the National Recording Registry o ...

Technical Crew
The technical crew, often abbreviated to the "tech crew" or simply the "crew" (individually often known as "techies", "techs", or "technicians"), are the people employed behind the scenes ("backstage") to control all the technical aspects of creating a concert, play, musical, opera or other live performance. The technical crew can consist of only a few individuals, or be divided up into a multitude of positions depending on the scale and needs of a particular production. The roles, composition and number of workers in a tech crew can change significantly depending on the nature of an event, and often evolves as the production does. In a small scale production, the technical crew might consist of a single person, operating the lights and controlling the volume of the sounds and music. In a large scale productions, the technical crew can consist of dozens of different departments and may run into the hundreds of individuals. Each department has their own specific job that pertains to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or '' voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power ...

Headset (audio)
Headsets connect over a telephone or to a computer, allowing the user to speak and listen while keeping both hands free. They are commonly used in customer service and technical support centers, where employees can converse with customers while typing information into a computer. Also common among computer gamers are headsets, which will let them talk with each other and hear others, as well as use their keyboards and mice to play the game. Types Telephone headsets generally use loudspeakers with a narrower frequency range than those also used for entertainment. Stereo computer headsets, on the other hand, use 32-ohm speakers with a broader frequency range. Mono and stereo Headsets are available in single-earpiece and double-earpiece designs. Double-earpiece headsets may support stereo sound or use the same monaural audio channel for both ears. Single-earpiece headsets free up one ear, allowing better awareness of surroundings. Telephone headsets are monaural, even for do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shielded Cable
A shielded cable or screened cable is an electrical cable that has a common conductive layer around its conductors for electromagnetic shielding. This shield is usually covered by an outermost layer of the cable. Common types of cable shielding can most broadly be categorized as foil type (hereunder: metallised film), contraspiralling wire strands ( braided or unbraided) or both. A longitudinal wire may be necessary with dielectric spiral foils to short out each turn. The shield acts as a Faraday cage – a surface that reflects electromagnetic radiation. This reduces both the interference from outside noise onto the signals and the signals from radiating out and potentially disturbing other devices (see electromagnetic compatibility). To be effective against electric fields (see also capacitive coupling), the shield must be grounded. The shield should be electrically continuous to maximize effectiveness, including any cable splices. For high frequency signals (above a few ...

Duplex (telecommunications)
A duplex communication system is a point-to-point system composed of two or more connected parties or devices that can communicate with one another in both directions. Duplex systems are employed in many communications networks, either to allow for simultaneous communication in both directions between two connected parties or to provide a reverse path for the monitoring and remote adjustment of equipment in the field. There are two types of duplex communication systems: full-duplex (FDX) and half-duplex (HDX). In a full-duplex system, both parties can communicate with each other simultaneously. An example of a full-duplex device is plain old telephone service; the parties at both ends of a call can speak and be heard by the other party simultaneously. The earphone reproduces the speech of the remote party as the microphone transmits the speech of the local party. There is a two-way communication channel between them, or more strictly speaking, there are two communication chann ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
