1176 Peak Limiter
The 1176 Peak Limiter is a dynamic range compressor designed by Bill Putnam and introduced by UREI in 1967. Derived from the 175 and 176 tube compressors, it marked the transition from vacuum tubes to solid-state technology. With its distinctive tone and its wide range of sounds, deriving from the Class A amplifiers, its input and output transformers, the uncommonly fast attack and release times and their program dependence, and different compression ratios and modes, the 1176 was immediately appreciated by engineers and producers and established as a studio standard through the years. At the time of its introduction, it was the first true peak limiter with all solid-state circuitry. The 1176LN was inducted into the TECnology Hall of Fame in 2008. History In 1966, Bill Putnam, engineer and founder of Universal Audio, began to employ the recently invented field-effect transistors (FET), replacing vacuum tubes in his equipment designs. After successfully adapting the 108 tube ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Universal Audio
United Recording Electronics Industries (UREI) was a manufacturer of recording, mixing and audio signal processing hardware for the professional recording studio, live sound and broadcasting fields. History Bill Putnam Sr. founded Universal Audio in Chicago in the 1950s as a design and manufacturing addition to his recording studio business, Universal Recording Corporation.

LA-2A Leveling Amplifier
The LA-2A Leveling Amplifier is an audio compressor produced by Teletronix Engineering Company from 1965 until 1969, and reissued in 2000 by Universal Audio. History The LA-2A was invented by James F. Lawrence II, founder of the Teletronix Engineering Company in Pasadena, California in the early 1960s. The LA-2A had evolved from Lawrence's first leveling amplifier, the LA-1, which was favored by Gene Autry, and its successor, the LA-2, which had been adopted by CBS and RCA. In 1965, Lawrence sold Teletronix to Babcock Electronics of Costa Mesa, California, and in 1967 Bill Putnam's company Studio Electronics (eventually renamed UREI), acquired Babcock's broadcast division, including the Teletronix brand. Three versions of the LA-2A were made until 1969. After Universal Audio was re-established in 1999, the company re-issued an updated version of the LA-2A. The LA-2A was inducted into the TECnology Hall of Fame in 2004. Design The LA-2A is a hand-wired, tube-based compressor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Faceplate (housing)
In engineering, a housing or enclosure is a container, a protective exterior (e.g. shell (structure), shell) or an enclosing structural element (e.g. chassis or exoskeleton) designed to enable easier handling, provide attachment points for internal mechanisms (e.g. mounting brackets for electrical components, electrical cable, cables and pipings), maintain cleanliness of the contents by shielding dirt/dust, fouling and other contaminations, or protect interior mechanisms (e.g. delicate integrated electrical fittings) from structural load, structural Stress (mechanics), stress and/or potential physical, thermal, chemical, biological or radiational damages from the surrounding environment. Housing may also be the body of a device, vital to its function. Description Housing is an exterior case or enclosure used to protect an interior mechanism. The housing prevents the interior mechanism from being fouled by outside debris. It may also have integrated fittings or brackets to keep in ...

Harmonic Distortion
In signal processing, distortion is the alteration of the original shape (or other characteristic) of a signal. In communications and electronics it means the alteration of the waveform of an information-bearing signal, such as an audio signal representing sound or a video signal representing images, in an electronic device or communication channel. Distortion is usually unwanted, and so engineers strive to eliminate or minimize it. In some situations, however, distortion may be desirable. For example, in noise reduction systems like the Dolby system, an audio signal is deliberately distorted in ways that emphasize aspects of the signal that are subject to electrical noise, then it is symmetrically "undistorted" after passing through a noisy communication channel, reducing the noise in the received signal. Distortion is also used as a musical effect, particularly with electric guitars. The addition of noise or other outside signals (hum, interference) is not considered di ...

Variable Mu
The control grid is an electrode used in amplifying thermionic valves (vacuum tubes) such as the triode, tetrode and pentode, used to control the flow of electrons from the cathode to the anode (plate) electrode. The control grid usually consists of a cylindrical screen or helix of fine wire surrounding the cathode, and is surrounded in turn by the anode. The control grid was invented by Lee De Forest, who in 1906 added a grid to the Fleming valve (thermionic diode) to create the first amplifying vacuum tube, the Audion (triode). Operation In a valve, the hot cathode emits negatively charged electrons, which are attracted to and captured by the anode, which is given a positive voltage by a power supply. The control grid between the cathode and anode functions as a "gate" to control the current of electrons reaching the anode. A more negative voltage on the grid will repel the electrons back toward the cathode so fewer get through to the anode. A less negative, or positive, ...

Microphone Preamplifier
The term microphone preamplifier can either refer to the electronic circuitry within a microphone, or to a separate device or circuit that the microphone is connected to. In either instance, the purpose of the microphone preamplifier is the same. A microphone preamplifier is a sound engineering device that prepares a microphone signal to be processed by other equipment. Microphone signals are often too weak to be transmitted to units such as mixing consoles and recording devices with adequate quality. Preamplifiers increase a microphone signal to line level (i.e. the level of signal strength required by such devices) by providing stable gain while preventing induced noise that would otherwise distort the signal.Ballou, 1987, pp. 506–507. For additional discussion of signal level, see Gain stage. A microphone preamplifier is colloquially called a microphone preamp, mic preamp, micamp, preamp (not to be confused with a control amplifier in high-fidelity reproduction equipment), ...

Field-effect Transistor
The field-effect transistor (FET) is a type of transistor that uses an electric field to control the flow of current in a semiconductor. FETs (JFETs or MOSFETs) are devices with three terminals: ''source'', ''gate'', and ''drain''. FETs control the flow of current by the application of a voltage to the gate, which in turn alters the conductivity between the drain and source. FETs are also known as unipolar transistors since they involve single-carrier-type operation. That is, FETs use either electrons (n-channel) or holes (p-channel) as charge carriers in their operation, but not both. Many different types of field effect transistors exist. Field effect transistors generally display very high input impedance at low frequencies. The most widely used field-effect transistor is the MOSFET (metal-oxide-semiconductor field-effect transistor). History The concept of a field-effect transistor (FET) was first patented by Austro-Hungarian physicist Julius Edgar Lilienfeld in 192 ...

Dynamic Range Compression
Dynamic range compression (DRC) or simply compression is an audio signal processing operation that reduces the volume of loud sounds or amplifies quiet sounds, thus reducing or ''compressing'' an audio signal's dynamic range. Compression is commonly used in sound recording and reproduction, broadcasting, sound reinforcement system, live sound reinforcement and in some instrument amplifiers. A dedicated electronic hardware unit or audio software that applies compression is called a compressor. In the 2000s, compressors became available as software plugins that run in digital audio workstation software. In recorded and live music, compression parameters may be adjusted to change the way they affect sounds. Compression and limiting are identical in process but different in degree and perceived effect. A limiter is a compressor with a high #Ratio, ratio and, generally, a short #Attack and release, attack time. Types There are two types of compression, downward and upward. Bot ...

TEC Awards
The TEC Awards is an annual program recognizing the achievements of audio professionals. The awards are given to honor technically innovative products as well as companies and individuals who have excelled in sound for television, film, recordings, and concerts. ''TEC'' is an acronym for Technical Excellence and Creativity. History The awards were founded in 1985 by ''Mix'' magazine, with awards events held annually at Audio Engineering Society conventions. In 1990, the TEC Foundation for Excellence in Audio, a 501(c)(3) (non-profit) public benefit organization that also offered scholarships and worked to mitigate noise-induced hearing loss, assumed responsibility for the awards. In 2011, the TEC Awards program was held at the NAMM Show, and in 2013 the TEC Foundation was merged with the NAMM Foundation, the educational and charitable arm of NAMM. Awards process The TEC Awards list of nominations are compiled annually by the TEC Awards nominating panel, a committee of more than 1 ...
