James Bullough Lansing
James Bullough Lansing (born James Martini, January 2, 1902 – September 29, 1949) was a pioneering American audio engineer and loudspeaker designer who was most notable for establishing two audio companies that bear his name, Altec Lansing and JBL, the latter taken from his initials, JBL. Biography Early years James Martini was born on January 2, 1902, in Greenridge, Nilwood Township, Macoupin County, Illinois to parents Henry Martini of St. Louis, Missouri, and Grace Erbs Martini of Central City, Illinois. His father was a coal mining engineer which meant the family moved around considerably in James' early years. He was the ninth of fourteen children. He lived for a short time with the Bullough family in Springfield, Illinois, and later took their name.

Studio Monitors
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 ("uncolored" and "transparent" are synonyms), 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 ''n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Altec Lansing
Altec Lansing, Inc. is an American 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 ...

Wireless Speakers
Wireless speakers are loudspeakers that receive audio signals using radio frequency (RF) waves rather than over audio cables. The two most popular RF frequencies that support audio transmission to wireless loudspeakers include a variation of WiFi IEEE 802.11, while others depend on Bluetooth to transmit audio data to the receiving speaker. Apart from the employed RF standard, such speakers can basically be distinguished by their dedicated field of use. Portable wireless speakers for outdoor use are typically designed for ruggedness, portability and battery life, whereas stationary wireless speakers with a focus on good sound quality are meant to be used in home audio systems or surround sound systems for TV or video. Further, types for special applications like waterproof speakers for use in the shower or speakers for a Voice user interface, voice assistant may intermix between the properties of the two former.

Vehicle Audio
Vehicle audio is equipment installed in a car or other vehicle to provide in-car entertainment and information for the occupants. Such systems are popularly known as car stereos. Until the 1950s, it consisted of a simple AM radio. Additions since then have included FM radio (1952), 8-track tape players, Cassette decks, record players, CD players, DVD players, Blu-ray players, navigation systems, Bluetooth telephone integration and audio streaming, and smartphone controllers like CarPlay and Android Auto. Once controlled from the dashboard with a few buttons, they can be controlled by steering wheel controls and voice commands. Initially implemented for listening to music and radio, vehicle audio is now part of car telematics, telecommunications, in-vehicle security, handsfree calling, navigation, and remote diagnostics systems. The same loudspeakers may also be used to minimize road and engine noise with active noise control, or they may be used to augment engine sounds, fo ...

Public Address System
A public address system (or PA system) is an electronic system comprising microphones, amplifiers, loudspeakers, and related equipment. It increases the apparent volume (loudness) of a human voice, musical instrument, or other acoustic sound source or recorded sound or music. PA systems are used in any public venue that requires that an announcer, performer, etc. be sufficiently audible at a distance or over a large area. Typical applications include sports stadiums, public transportation vehicles and facilities, and live or recorded music venues and events. A PA system may include multiple microphones or other sound sources, a mixing console to combine and modify multiple sources, and multiple amplifiers and loudspeakers for louder volume or wider distribution. Simple PA systems are often used in small venues such as school auditoriums, churches, and small bars. PA systems with many speakers are widely used to make announcements in public, institutional and commercial buildings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
