United Recording Electronics Industries
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. After Putnam moved to Hollywood in 1957 and established the United Recording Corporation, his company acquired Studio Supply Co. and rebranded it as the Studio Electronics Corporation (SEC) and moved all manufacturing to the second floor of Western Recorders. By December, 1965, Universal Audio had been completely absorbed by Studio Electronics, although Studio Electronics continued to produce some Universal Audio-branded products. In 1967, Studio Electronics acquired the broadcast division of Babcock Electronics, including Teletronix and the patent rights to the electro-optical LA-2A leveling amplifier ...

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] |
Rudy Bozak
Rudolph Thomas Bozak (1910–1982) was an audio electronics and acoustics designer and engineer in the field of sound reproduction. His parents were Bohemian Czech immigrants; Rudy was born in Uniontown, Pennsylvania. Bozak studied at Milwaukee School of Engineering; in 1981, the school awarded him an honorary doctorate in engineering. Bozak married Lillian Gilleski; the two had three daughters: Lillian, Mary and Barbara. Loudspeakers Fresh out of college in 1933, Rudy Bozak began working for Allen-Bradley, an electronics manufacturer based in Milwaukee, Wisconsin. Bozak would later employ Allen-Bradley components in his own electronic designs. Bozak moved to the East Coast in 1935 to work for Cinaudagraph out of Stamford, Connecticut. Two years later he was chief engineer. At the 1939 New York World's Fair, a tower topped with a cluster of eight 27" Cinaudagraph loudspeakers in 30" frames with huge 450 lb. field coil magnets covered low frequency duties for a 2-way P ...

Soundcraft
Soundcraft is a British designer and importer (formerly a manufacturer) of mixing consoles and other professional audio equipment. It is a subsidiary of Harman International Industries, which is owned by South Korean company Samsung Electronics. It was founded by sound engineer Phil Dudderidge and electronics designer Graham Blyth in 1973. History Soundcraft first made its mark by manufacturing the Series 1, the first mixing console built into a flight-case. It was available with 12 or 16 input channels and 4 outputs—main stereo, plus a post-fader ‘echo’ send and pre-fader foldback. Each channel had four-band fixed-frequency EQ. The Series 1 also included a multi-pin connector that integrated with a multi-channel microphone snake to route signals from and to the stage from a mix position in the audience. The Series 1S was introduced in 1975 as an upgraded Series 1. The Series 1S introduced the classic Soundcraft four-band EQ with two sweepable mid-range sections. In ad ...

Altec Lansing
Altec Lansing, Inc. is a U.S. audio electronics company founded in 1927. Their primary products are loudspeakers and associated audio electronics for professional, home, automotive and multimedia applications. Engineers at Western Electric, who later formed Altec Services Company, developed the technology for motion picture sound that was introduced in 1927, with the release of ''The Jazz Singer''. Originally, Altec Services Company serviced the theater sound systems the company founders had helped develop. In 1941 the Altec Services Company purchased the nearly bankrupt Lansing Manufacturing Company and melded the two names, forming the Altec Lansing Corporation, and with the manufacturing capabilities of the former Lansing Manufacturing Company, they quickly expanded into manufacturing horn loudspeakers. In 1958 the Altec Lansing Corporation was purchased by James Ling who made it part of LTV Ling Altec. LTV spun off Altec which it loaded down with debt first. By 1974, the c ...

Leveling Amplifier
An audio leveler performs an audio process similar to compression, which is used to reduce the dynamic range of a signal, so that the quietest portion of the signal is loud enough to hear and the loudest portion is not too loud. Levelers work especially well with vocals, as there are huge dynamic differences in the human voice and levelers work in such a way as to sound very natural, letting the character of the sound change with the different levels but still maintaining a predictable and usable dynamic range. A leveler is different from a compressor in that the ratio and threshold are controlled with a single control.

Audio Signal Processing
Audio signal processing is a subfield of signal processing that is concerned with the electronic manipulation of audio signals. Audio signals are electronic representations of sound waves—longitudinal waves which travel through air, consisting of compressions and rarefactions. The energy contained in audio signals is typically measured in decibels. As audio signals may be represented in either digital or analog format, processing may occur in either domain. Analog processors operate directly on the electrical signal, while digital processors operate mathematically on its digital representation. History The motivation for audio signal processing began at the beginning of the 20th century with inventions like the telephone, phonograph, and radio that allowed for the transmission and storage of audio signals. Audio processing was necessary for early radio broadcasting, as there were many problems with studio-to-transmitter links. The theory of signal processing and its appli ...
