QSC Audio Products
QSC is an American manufacturer of audio products including power amplifiers, loudspeakers, digital mixers and digital signal processors including the Q-Sys networked audio, video and control platform. QSC products are used by professional installed, portable, production, corporate and cinema customers worldwide. History The company was founded in 1968 by Patrick Howe Quilter, who serves as chairman of the board of directors. Quilter was at the time an engineering student with a keen interest in electronics and music. In 1967 Quilter had learned that the bass player in his brother’s high school band was searching for an affordable bass amp. When Quilter learned his budget was $250.00, he said “I could probably make you something for that kind of money,” giving birth to the first QSC amp. With many musician friends and acquaintances seeking him out to make guitar amps, he left school to start his company with the financial backing of family and friends. At first the compan ...

Privately Held Company
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or Over-the-counter (finance), over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their public company, publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''. In 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Class-D Amplifier
A class-D amplifier or switching amplifier is an electronic amplifier in which the amplifying devices (transistors, usually MOSFETs) operate as electronic switches, and not as linear gain devices as in other amplifiers. They operate by rapidly switching back and forth between the supply rails, being fed by a modulator using pulse width, pulse density, or related techniques to encode the audio input into a pulse train. The audio passes through a simple low-pass filter into the loudspeaker. The high-frequency pulses are blocked. Since the pairs of output transistors are never conducting at the same time, there is no other path for current flow apart from the low-pass filter/loudspeaker. For this reason, efficiency can exceed 90%. History The first Class-D amplifier was invented by British scientist Alec Reeves in the 1950s and was first called by that name in 1955. The first commercial product was a kit module called the X-10 released by Sinclair Radionics in 1964. Howev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electronics Companies Established In 1968
The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering, which only uses passive effects such as resistance, capacitance and inductance to control electric current flow. Electronics has hugely influenced the development of modern society. The central driving force behind the entire electronics industry is the semiconductor industry sector, which has annual sales of over $481 billion as of 2018. The largest industry sector is e-commerce, which generated over $29 trillion in 2017. History and development Electronics has hugely influenced the development of modern society. The identification of the electron in 1897, along with the subsequent invention of the vacuum tube which could amplify and rectify small el ...

CobraNet
CobraNet is a combination of software, hardware, and network protocols designed to deliver Audio data compression, uncompressed, multi-channel, Latency (audio), low-latency digital audio over a standard Ethernet network. Developed in the 1990s, CobraNet is widely regarded as the first commercially successful audio over Ethernet, audio-over-Ethernet implementation. CobraNet was designed for and is primarily used in large commercial audio installations such as convention centers, stadiums, airports, theme parks, and concert halls. It has applications where a large number of audio channels must be transmitted over long distances or to multiple locations. CobraNet is an alternative to analog audio, which suffers from signal degradation over long cable runs due to electromagnetic interference, high-frequency attenuation, and voltage drop. Additionally, the use of digital multiplexing allows audio to be transmitted using less cabling than analog audio. History CobraNet was develop ...
