Threshold Audio
Threshold Audio is a high-end audio equipment manufacturer originally established in California in 1974 by audio engineer Nelson Pass and graphic designer René Besne. The company, today based in Houston Texas, manufactures mono-block and stereo power amplifiers, multi-channel power amplifiers and stereo control amplifiers. Nelson Pass and the founding of Threshold In the early 1970s, Nelson Pass was studying Physics at the University of California-Davis. While a student, he founded PMA to design and manufacture speakers. In 1972, he joined ESS speakers in Sacramento just prior to the arrival of Oscar Heil, who would design the Heil Air Motion Transformer which was a key component of the ESS AMT series of speakers. Pass worked at ESS designing crossovers and enclosures through 1973. He also was a service manager for Sun Stereo performing repairs on McIntosh Laboratory, Phase Linear, Pioneer Corporation and other brands of amplifiers, and began formulating his own amplifier design ...

Physics
Physics is the scientific study of matter, its Elementary particle, fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." It is one of the most fundamental scientific disciplines. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physics. (...) You will come to see physics as a towering achievement of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phase Linear
Phase Linear was an audio equipment manufacturer founded by Bob Carver and Steve Johnston in 1970. While primarily known as a power amplifier company it also produced several innovative preamplifiers, tuners and the Andromeda loudspeaker. History Its first location was 19555 23rd Ave. N.W. Seattle, Washington. Its second location was a small building at 405 Howell Way in Edmonds, Washington. The first amplifier produced was the Phase Linear 700. With 350 watts per channel it soon became the standard amplifier used by recording studios, sound reinforcement companies, professional musicians and audiophiles. It had a retail price of $749.00, or a little more than a dollar a watt. The design was notable for its brushed aluminum front panel and large dual VU meters, and was made possible by the new high-power transistors designed for the high voltages of auto electronic ignitions. That original amp was replaced by the 700B and the 700 II. All of those designs were made to hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amplifier
An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the magnitude of a signal (a time-varying voltage or current). It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude (magnitude of the voltage or current) of a signal applied to its input terminals, producing a proportionally greater amplitude signal at its output. The amount of amplification provided by an amplifier is measured by its gain: the ratio of output voltage, current, or power to input. An amplifier is defined as a circuit that has a power gain greater than one. An amplifier can be either a separate piece of equipment or an electrical circuit contained within another device. Amplification is fundamental to modern electronics, and amplifiers are widely used in almost all electronic equipment. Amplifiers can be categorized in different ways. One is by the frequency of the electronic signal being amplified. For ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Industrial Design
Industrial design is a process of design applied to physical Product (business), products that are to be manufactured by mass production. It is the creative act of determining and defining a product's form and features, which takes place in advance of the manufacture or production of the product. Industrial manufacture consists of predetermined, standardized and repeated, often automated, acts of replication, while craft-based design is a process or approach in which the form of the product is determined personally by the product's creator largely concurrent with the act of its production. All manufactured products are the result of a design process, but the nature of this process can vary. It can be conducted by an individual or a team, and such a team could include people with varied expertise (e.g. designers, engineers, business experts, etc.). It can emphasize intuitive creativity or calculated Evidence-based design, scientific decision-making, and often emphasizes a mix of b ...
