Virtue Audio
Virtue Audio is a manufacturer of integrated amplifiers based on the Tripath microprocessor chip, also known as a, class-T, class D or switching amplifier. The company produces unusually small, brightly colored, value-priced amplifiers that produce higher wattage than normally found at their price. Design consultants include Roger Sheker, chief engineer for high-end audio companAudience maker of the Auricap capacitor. Principals Virtue Audio was founded in 2005 by Seth Krinsky. Krinsky is said to have purchased thousands of dollars worth of Tripath chips as the chip-maker was entering bankruptcy, even before he had an amplifier designed for them. EngineeMichael Mardisperformed initial design work on the Virtue amplifiers and rejoined the company in 2009. Sheker joined the project after Virtue sourced caps and wire from Audience.Whetstone, Nick Sept. 2008, retrieved 5-13-09 Products The company's core products are the Virtue One and Virtue Two integrated digital amplifiers.

Amplifiers
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 may increase the power significantly, or its main effect may be to boost the voltage or current (power, voltage or current amplifier). It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals, producing a greater amplitude signal at its output. The ratio of output to input voltage, current, or power is termed gain (voltage, current, or power gain). An amplifier, by definition has gain greater than unity (if the gain is less than unity, the device is an attenuator). An amplifier can either be 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 categoriz ...

Tripath
Class T was a registered trademark for a switching (class-D) audio amplifier, used for Tripath's amplifier technologies (patent filed on Jun 20, 1996). Similar designs have now been widely adopted by different manufacturers. Amplifier The covered products use a class-D amplifier combined with proprietary techniques to control the pulse-width modulation to produce what is claimed to be better performance than other class-D amplifier designs. Among the publicly disclosed differences is real time control of the switching frequency depending on the input signal and amplified output. One of the amplifiers, the TA2020, was named one of the twenty-five chips that 'shook the world" by the ''IEEE Spectrum'' magazine. The control signals in Class T amplifiers may be computed using digital signal processing or fully analog techniques. Currently available implementations use a loop similar to a higher order Delta-Sigma (ΔΣ) (or sigma-delta) modulator, with an internal digital clock to co ...

Switching 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. Howeve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capacitor
A capacitor is a device that stores electrical energy in an electric field by virtue of accumulating electric charges on two close surfaces insulated from each other. It is a passive electronic component with two terminals. The effect of a capacitor is known as capacitance. While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed to add capacitance to a circuit. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the ''condenser microphone''. The physical form and construction of practical capacitors vary widely and many types of capacitor are in common use. Most capacitors contain at least two electrical conductors often in the form of metallic plates or surfaces separated by a dielectric medium. A conductor may be a foil, thin film, sintered bead of metal, or an electrolyte. The nonconducting dielectric acts to increase the capacitor's c ...

Denver, Colorado
Denver () is a consolidated city and county, the capital, and most populous city of the U.S. state of Colorado. Its population was 715,522 at the 2020 census, a 19.22% increase since 2010. It is the 19th-most populous city in the United States and the fifth most populous state capital. It is the principal city of the Denver–Aurora–Lakewood, CO Metropolitan Statistical Area and the first city of the Front Range Urban Corridor. Denver is located in the Western United States, in the South Platte River Valley on the western edge of the High Plains just east of the Front Range of the Rocky Mountains. Its downtown district is immediately east of the confluence of Cherry Creek and the South Platte River, approximately east of the foothills of the Rocky Mountains. It is named after James W. Denver, a governor of the Kansas Territory. It is nicknamed the ''Mile High City'' because its official elevation is exactly one mile () above sea level. The 105th meridian we ...
