Dolby Noise-reduction System
A Dolby noise-reduction system (Dolby NR) is one of a series of audio noise reduction, noise reduction systems developed by Dolby Laboratories for use in analog audio tape recording. The first was #Dolby A, Dolby A, a professional broadband noise reduction system for recording studios that was first demonstrated in 1965, but the best-known is #Dolby B, Dolby B (introduced in 1968), a sliding band system for the consumer market, which helped make high fidelity practical on cassette tapes, which used a relatively noisy tape size and speed. It is common on high-fidelity stereo tape players and recorders to the present day. Of the noise reduction systems, Dolby A and #Dolby SR, Dolby SR were developed for professional use. Dolby B, #Dolby C, C, and #Dolby S, S were designed for the consumer market. Aside from #Dolby HX/HX-Pro, Dolby HX, all the Dolby variants work by companding: compressing the dynamic range of the sound during recording, and expanding it during playback. Process W ...

Loudspeaker
A loudspeaker (commonly referred to as a speaker or, more fully, a speaker system) is a combination of one or more speaker drivers, an enclosure, and electrical connections (possibly including a crossover network). The speaker driver is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound. The driver is a linear motor connected to a diaphragm, which transmits the motor's movement to produce sound by moving air. An audio signal, typically originating from a microphone, recording, or radio broadcast, is electronically amplified to a power level sufficient to drive the motor, reproducing the sound corresponding to the original unamplified signal. This process functions as the inverse of a microphone. In fact, the ''dynamic speaker'' driver—the most common type—shares the same basic configuration as a dynamic microphone, which operates in reverse as a generator. The dynamic speaker was invented in 1925 by Edward W. Kellogg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birmingham Sound Reproducers
Birmingham Sound Reproducers (BSR) was a 20th-century British manufacturer of record player turntables, reel-to-reel tape recorder mechanisms and, for a time, housewares. History Early years Daniel McLean McDonald (1905–1991) founded Birmingham Sound Reproducers as a private company in 1932 in the West Midlands (region), West Midlands of England. By 1947, the company chiefly manufactured communications sets (intercoms), laboratory test equipment, and sound recording and reproducing instruments including phonographs. Record turntables and related products In the early 1950s, Samuel Margolin began buying Record changer, auto-changing turntables from BSR, using them as the basis of his Dansette record player. Over the next twenty years, Margolin manufactured more than a million of these players, and "Dansette" became a household word in Britain. In 1957, BSR, also known by the name BSR McDonald, became a public company which by 1961 had grown to employ 2,600. It supplied ...

Mixing Console
A mixing console or mixing desk is an electronic device for Audio mixing (recorded music), mixing audio signals, used in sound recording and reproduction and sound reinforcement systems. Inputs to the console include microphones, signals from electric or electronic instruments, or recorded sounds. Mixers may control analog or Digital signal (signal processing), digital signals. The modified signals are summation, summed to produce the combined output signals, which can then be broadcast, amplified through a sound reinforcement system or recorded. Mixing consoles are used for applications including recording studios, public address systems, sound reinforcement systems, nightclubs, broadcasting, and post-production. A typical, simple application combines signals from microphones on stage into an amplifier that drives one set of loudspeakers for the audience. A DJ mixer may have only two channels, for mixing two record players. A coffeehouse's small stage might only have a six-c ...

Root Mean Square
In mathematics, the root mean square (abbrev. RMS, or rms) of a set of values is the square root of the set's mean square. Given a set x_i, its RMS is denoted as either x_\mathrm or \mathrm_x. The RMS is also known as the quadratic mean (denoted M_2), a special case of the generalized mean. The RMS of a continuous function is denoted f_\mathrm and can be defined in terms of an integral of the square of the function. In estimation theory, the root-mean-square deviation of an estimator measures how far the estimator strays from the data. Definition The RMS value of a set of values (or a continuous-time waveform) is the square root of the arithmetic mean of the squares of the values, or the square of the function that defines the continuous waveform. In the case of a set of ''n'' values \, the RMS is : x_\text = \sqrt. The corresponding formula for a continuous function (or waveform) ''f''(''t'') defined over the interval T_1 \le t \le T_2 is : f_\text = \sqrt , and the R ...

Voltage Controlled Amplifier
A variable-gain (VGA) or voltage-controlled amplifier (VCA) is an electronic amplifier that varies its gain depending on a control voltage (often abbreviated CV). VCAs have many applications, including audio level compression, synthesizers and amplitude modulation. A crude example is a typical inverting op-amp configuration with a light-dependent resistor (LDR) in the feedback loop. The gain of the amplifier then depends on the light falling on the LDR, which can be provided by an LED (an optocoupler). The gain of the amplifier is then controllable by the current through the LED. This is similar to the circuits used in optical audio compressors. A voltage-controlled amplifier can be realised by first creating a voltage-controlled resistor (VCR), which is used to set the amplifier gain. The VCR is one of the numerous interesting circuit elements that can be produced by using a JFET (junction field-effect transistor) with simple biasing. VCRs manufactured in this way can be ...

Blackmer Gain Cell
The Blackmer gain cell is an audio frequency voltage-controlled amplifier (VCA) circuit with an Exponential function, exponential control law. It was invented and patented by David E. Blackmer between 1970 and 1973. The four-transistor core of the original Blackmer cell contains two complementary bipolar transistor, bipolar current mirrors that perform Log amplifier, log-antilog operations on input voltages in a push-pull, alternating fashion. Earlier log-antilog modulators using the fundamental Shockley diode equation, exponential characteristic of a p–n junction were unipolar; Blackmer's application of push-pull signal processing allowed modulation of bipolar voltages and bidirectional currents. The Blackmer cell, which has been manufactured since 1973, is the first precision VCA circuit that was suitable for professional audio. As early as the 1970s, production Blackmer cells achieved dynamic range, control range with total harmonic distortion of no more than 0.01% and very hi ...
