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 connector ...

AMX192
AMX192 (often referred to simply as AMX) is an analog lighting communications protocol used to control stage lighting. It was developed by Strand Century in the late 1970s. Originally, AMX192 was only capable of controlling 192 discrete channels of lighting. Later, multiple AMX192 streams were supported by some lighting desks. AMX192 has mostly been replaced in favour of DMX, and is typically only found in legacy hardware. History The name AMX192 is derived from an acronym of Analog MultipleXing and the maximum number of controllable lighting channels (192). AMX was developed to address a significant problems in controlling dimmers. For many years, in order to send a control signal from a lighting control unit to the dimmer units, the only method available was to provide a dedicated wire from the control unit to each dimmer (analogue control) where the voltage present on the wire was varied by the control unit to set the output level of the dimmer. In the late 1970s, the AMX192 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Voyetra-8
The Voyetra-8 (Voyetra-Eight) is an eight voice polyphonic analog synthesizer. Released in 1982 by Octave-Plateau Electronics (later renamed Voyetra and still later merged with Turtle Beach Systems to become Voyetra Turtle Beach, Inc.), it was one of the first analog programmable synthesizers to be rack-mountable and remains one of the most flexible digitally controlled analog synthesizers. Design The Voyetra-8 is a 19" rack-mountable device, 3 rack units high at the face. Most units are bowed at the top and so cannot be placed below other rack mounted equipment more than a few inches deep. It is approximately 16 inches deep in the rack, and weighs around 38 lbs. Rear mounted plugs and a large heat sink make at least 4" rear clearance advisable. The front panel has numerous buttons and knobs, which are active in live performance. However, the instrument is more complicated than it looks; there are fourteen "pages" of controls. Extra "pages" are accessed by hitting certain shif ...

MIDI
MIDI (; Musical Instrument Digital Interface) is a technical standard that describes a communications protocol, digital interface, and electrical connectors that connect a wide variety of electronic musical instruments, computers, and related audio devices for playing, editing, and recording music. The specification originates in the paper ''Universal Synthesizer Interface'' published by Dave Smith and Chet Wood of Sequential Circuits at the 1981 Audio Engineering Society conference in New York City. A single MIDI cable can carry up to sixteen channels of MIDI data, each of which can be routed to a separate device. Each interaction with a key, button, knob or slider is converted into a MIDI event, which specifies musical instructions, such as a note's pitch, timing and loudness. One common MIDI application is to play a MIDI keyboard or other controller and use it to trigger a digital sound module (which contains synthesized musical sounds) to generate sounds, which t ...

Wheelchair
A wheelchair is a chair with wheels, used when walking is difficult or impossible due to illness, injury, problems related to old age, or disability. These can include spinal cord injuries ( paraplegia, hemiplegia, and quadriplegia), cerebral palsy, brain injury, osteogenesis imperfecta, motor neurone disease, multiple sclerosis, muscular dystrophy, spina bifida, and more. Wheelchairs come in a wide variety of formats to meet the specific needs of their users. They may include specialized seating adaptions, individualized controls, and may be specific to particular activities, as seen with sports wheelchairs and beach wheelchairs. The most widely recognized distinction is between motorized wheelchairs, where propulsion is provided by batteries and electric motors, and manual wheelchairs, where the propulsive force is provided either by the wheelchair user or occupant pushing the wheelchair by hand ("self-propelled"), by an attendant pushing from the rear using the handle( ...

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] |
Speakon Connector
The Speakon (stylized speakON) is a trademarked name for an electrical connector, originally manufactured by Neutrik, mostly used in professional audio systems for connecting loudspeakers to amplifiers. Other manufacturers make compatible products, often under the name "speaker twist connector". Speakon connectors are rated for at least 30 A RMS continuous current, higher than 1/4-inch TS phone connectors, two-pole twist lock, and XLR connectors for loudspeakers. Design A Speakon connector is designed with a locking system that may be designed for soldered or screw-type connections. Line connectors (female) mate with (male) panel connectors and typically a cable will have identical connectors at both ends. If it is needed to join cables, a coupler can be used (which essentially consists of two panel connectors mounted on the ends of a plastic tube). The design was conceived in 1987.https://www.neutrik.com/media/10094/download/product-guide---section-loundspeaker-connectors. ...

Trace Elliot
Trace Elliot is a United Kingdom-based bass amplification manufacturer, and has a sub-brand, Trace Acoustic, for acoustic instruments. History In 1979, a music shop in Romford, Essex, UK, called Soundwave was building and hiring out PA systems to local musicians. It soon became apparent that some of this equipment was not being used simply as PA but instead was being used by bass players, who for so long had to put up with under-powered amplification that was often merely a guitar amplifier with a modified tone circuit. The Soundwave owner, Fred Friedlein, and staff which included Alan Morgan (sales) and Stuart Watson (design engineer) realised the potential market and developed a range of products that incorporated MOSFET output stages driving large cabinets, including 15” drivers, and also the world's first bass-dedicated 4 x 10” cabinet, now an industry standard for all bass amp lines. There were several features which made this product unique: the GP11 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
