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.
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. [1] 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. [2]
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. [3] In anticipation of further acquisitions, SEC was rebranded as United Recording Electronics Industries, or UREI.
UREI subsequently acquired National Intertel; from this acquisition came technology which developed into the 1176 peak limiter in 1968, [4] and the 1108 FET preamp. Other notable products included the UREI Teletronix LA-3A electro-optical leveling amplifier, LA-4 electro-optical compressor limiter, [5] and UREI 500-series graphic equalizers. By 1976, UREI had moved their manufacturing and service center to Sun Valley, California.
UREI collaborated with Edward M. Long of E.M. Long Associates in Oakland, California to create the 813 family of time-aligned large-format studio monitor speakers, introduced in 1977. [6] The 813 and subsequent models introduced in 1979, including the 813A, 815A, and 811A, used Altec Lansing and Eminence drivers. In 1983, financial and quality control problems at Altec led UREI to introduce the 813B, which utilized JBL loudspeaker drivers. [7] [6]
Putnam sold UREI to Harman in 1983, and UREI became a division of JBL Professional. [6] Harman began releasing "JBL-UREI" co-branded products such as the 5547A graphic equalizer in 1986. [8]
In 2005, another Harman division, Soundcraft, introduced a "UREI-by-Soundcraft"-badged 1620LE mixer, with 'LE' standing for 'Limited Edition'. [9] The mixer was a re-issue of the UREI 1620, a 1980s-era clone of Rudy Bozak's classic 1960s-era rotary-style DJ mixer, the CMA-10-2DL. [10] Soundcraft provided the new product line with its own website.
A mixing console or mixing desk is an electronic device for 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 signals. The modified signals are summed to produce the combined output signals, which can then be broadcast, amplified through a sound reinforcement system or recorded.
A horn loudspeaker is a loudspeaker or loudspeaker element which uses an acoustic horn to increase the overall efficiency of the driving element(s). A common form (right) consists of a compression driver which produces sound waves with a small metal diaphragm vibrated by an electromagnet, attached to a horn, a flaring duct to conduct the sound waves to the open air. Another type is a woofer driver mounted in a loudspeaker enclosure which is divided by internal partitions to form a zigzag flaring duct which functions as a horn; this type is called a folded horn speaker. The horn serves to improve the coupling efficiency between the speaker driver and the air. The horn can be thought of as an "acoustic transformer" that provides impedance matching between the relatively dense diaphragm material and the less-dense air. The result is greater acoustic output power from a given driver.

United Western Recorders was a two-building recording studio complex in Hollywood that was one of the most successful independent recording studios of the 1960s. The complex merged neighboring studios United Recording Corp. on 6050 Sunset Boulevard and Western Studio on 6000 Sunset Boulevard.
Milton Tasker "Bill" Putnam was an American audio engineer, songwriter, producer, studio designer, and businessman. He has been described as "the father of modern recording". He was the inventor of the modern recording console and is recognized as having been a key figure in the development of the postwar commercial recording industry.
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.
Powered speakers, also known as self-powered speakers and active speakers, are loudspeakers that have built-in amplifiers. Powered speakers are used in a range of settings, including in sound reinforcement systems, both for the main speakers facing the audience and the monitor speakers facing the performers; by DJs performing at dance events and raves; in private homes as part of hi-fi or home cinema audio systems and as computer speakers. They can be connected directly to a mixing console or other low-level audio signal source without the need for an external amplifier. Some active speakers designed for sound reinforcement system use have an onboard mixing console and microphone preamplifier, which enables microphones to be connected directly to the speaker.
Harman International Industries, Inc., commonly known as Harman, is an American audio electronics company. Since 2017, the company has been operating as an independent subsidiary of Samsung Electronics.
Studio monitors are loudspeakers in speaker enclosures specifically designed for professional audio production applications, such as recording studios, filmmaking, television studios, radio studios and project or home studios, where accurate audio reproduction is crucial. Among audio engineers, the term monitor implies that the speaker is designed to produce relatively flat (linear) phase and frequency responses. In other words, it exhibits minimal emphasis or de-emphasis of particular frequencies, the loudspeaker gives an accurate reproduction of the tonal qualities of the source audio, and there will be no relative phase shift of particular frequencies—meaning no distortion in sound-stage perspective for stereo recordings. Beyond stereo sound-stage requirements, a linear phase response helps impulse response remain true to source without encountering "smearing". An unqualified reference to a monitor often refers to a near-field design. This is a speaker small enough to sit on a stand or desk in proximity to the listener, so that most of the sound that the listener hears is coming directly from the speaker, rather than reflecting off walls and ceilings. Monitor speakers may include more than one type of driver or, for monitoring low-frequency sounds, such as bass drum, additional subwoofer cabinets may be used.

Today, the company is known primarily for its power amplifiers, but has also manufactured microphones, loudspeakers, and a line of commercial audio products, as well as digital audio networking products.
A stage monitor system is a set of performer-facing loudspeakers called monitor speakers, stage monitors, floor monitors, wedges, or foldbacks on stage during live music performances in which a sound reinforcement system is used to amplify a performance for the audience. The monitor system allows musicians to hear themselves and fellow band members clearly.
The 1176 Peak Limiter is a dynamic range compressor designed by the American engineer 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.
A coaxial loudspeaker is a loudspeaker system in which the individual driver units radiate sound from the same point or axis. Two general types exist: one is a compact design using two or three speaker drivers, usually in car audio, and the other is a two-way high-power design for professional audio, also known as single-source or dual-concentric loudspeakers. The design is favored for its compactness and behavior as an audio point source.
Musical outboard equipment or outboard gear is used to process or alter a sound signal separately from functionality provided within a mixing console or a digital audio workstation. Outboard effects units can be used either during a live performance or in the recording studio.

DUPLEX was the trade name given by Altec Lansing to its line of coaxial loudspeakers, beginning with the first model 601 in 1943. However, the name was most commonly associated with the subsequent model 604 which was a seminal loudspeaker that became a milestone in loudspeaker development. Well over a dozen different models carried the Duplex name over a near 50-year period. The vast majority consisted of a high frequency (HF) compression driver mounted to the back of a large diameter paper cone low frequency (LF) driver. However, there were also a few models with small diameter LF cones and direct radiator tweeters.
