SM58
The Shure SM58 is a professional cardioid dynamic microphone, commonly used in live vocal applications. Produced since 1966 by Shure Incorporated, it has built a strong reputation among musicians for its durability and sound, and is still considered the industry standard for live vocal performance microphones to this day. The SM58 is the most popular live vocal microphone in the world. It is a development of the SM57 microphone; in both cases, SM stands for studio microphone. Overview Like all directional microphones, the SM58 is subject to proximity effect, a low-frequency boost when used close to the source. The cardioid response reduces pickup from the side and rear, helping to avoid feedback onstage. There are wired (with and without on/off switch) and wireless versions. The wired version provides balanced audio through a male XLR connector. The SM58 uses an internal shock mount to reduce handling noise. A distinctive feature of the SM58 is its pneumatic suspension system ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shure Incorporated
Shure Incorporated is an American audio products corporation. It was founded by Sidney N. Shure in Chicago, Illinois, in 1925 as a supplier of radio parts kits. The company became a consumer and professional audio-electronics manufacturer of microphones, wireless microphone systems, phonograph cartridges, discussion systems, mixers, and digital signal processing. The company also manufactures listening products, including headphones, high-end earphones, and personal monitor systems. Company history Shure was founded by Sidney N. Shure in 1925 as "The Shure Radio Company", selling radio parts kits several years after completely manufactured radios became commercially available. The company's office was located at 19 South Wells Street in downtown Chicago, Illinois. The following year, Shure published its first direct mail catalog, which was one of only six radio parts catalogs in the United States at the time. By 1928, the company had grown to over 75 employees, and Sidney ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cardioid Microphone
A microphone, colloquially called a mic or mike (), is a transducer that converts sound into an electrical signal. Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, sound recording, two-way radios, megaphones, and radio and television broadcasting. They are also used in computers for recording voice, speech recognition, VoIP, and for other purposes such as ultrasonic sensors or knock sensors. Several types of microphone are used today, which employ different methods to convert the air pressure variations of a sound wave to an electrical signal. The most common are the dynamic microphone, which uses a coil of wire suspended in a magnetic field; the condenser microphone, which uses the vibrating diaphragm as a capacitor plate; and the contact microphone, which uses a crystal of piezoelectric material. Microphones typically ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shure SM57
The Shure SM57 is a low- impedance cardioid dynamic microphone made by Shure Incorporated and commonly used in live sound reinforcement and studio recording. It is one of the best-selling microphones in the world. It is used extensively in amplified music and has been used for speeches by every U.S. president since its introduction in 1965.TECnology Hall of Fame: 2004 In 2004, honoring its four decades of "solid, dependable performance", it was inducted into the first-ever TEC Awards TECnology Hall of Fame.

Shure Beta 58A
The Shure Beta 58A is a rugged dynamic supercardioid microphone developed by Shure Incorporated specifically for live vocal performances. The microphone won a TEC Award in 1996 for outstanding microphone technology. Shure's Beta series of microphones was introduced in 1989. Originally the Beta 58 was available as the Beta 58C (chrome grill) or the Beta 58M (matte grill). The Beta 58C was eventually discontinued and the Beta 58M became just the Beta 58. The Beta 58 was then discontinued and replaced by the Beta 58A. Development In 1996, Shure altered the Beta 58 to create the Beta 58A, with a completely new cartridge design, meant to mimic the old cartridge as far as polar pattern, output level, and frequency response, but with slightly different sound characteristics; the revised design also removed the hum-bucking coil and added an output transformer. Comparisons Regarding the difference between the Beta 58 and Beta 58A, the manufacturer's website says, "The Beta 58A has a c ...

Shure MV7
The Shure MV7 is a cardioid dynamic microphone used for podcasting and home studio applications. The MV7 was developed in 2020 by Shure as a digital audio reworking of the classic SM7B professional broadcasting microphone. The MV7 was rated the best podcasting microphone by ''Rolling Stone'' in their 2021 Audio Awards. Designed to be mounted on a stand or boom arm, the MV7 can send its audio signal through a USB cable to a Macintosh or Windows computer, or to Android or iOS devices. To augment the microphone's capabilities, Shure supplies Motiv, a free-to-use proprietary software application intended to simplify the recording or streaming process for each operating system. The MV7 is certified with the Apple MFi Program and is compatible with the VoIP application TeamSpeak, to allow chat channel communication with others online. The microphone can also be connected to professional audio equipment using the XLR connector on the back, with both the XLR and the USB connectors wor ...

Audio Feedback
Audio feedback (also known as acoustic feedback, simply as feedback) is a positive feedback situation which may occur when an acoustic path exists between an audio input (for example, a microphone or guitar pickup) and an audio output (for example, a loudspeaker). In this example, a signal received by the microphone is amplified and passed out of the loudspeaker. The sound from the loudspeaker can then be received by the microphone again, amplified further, and then passed out through the loudspeaker again. The frequency of the resulting howl is determined by resonance frequencies in the microphone, amplifier, and loudspeaker, the acoustics of the room, the directional pick-up and emission patterns of the microphone and loudspeaker, and the distance between them. The principles of audio feedback were first discovered by Danish scientist Søren Absalon Larsen, hence it is also known as the Larsen effect. Feedback is almost always considered undesirable when it occurs with a sin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low Frequency
Low frequency (LF) is the ITU designation for radio frequencies (RF) in the range of 30–300 kHz. Since its wavelengths range from 10–1 km, respectively, it is also known as the kilometre band or kilometre wave. LF radio waves exhibit low signal attenuation, making them suitable for long-distance communications. In Europe and areas of Northern Africa and Asia, part of the LF spectrum is used for AM broadcasting as the "longwave" band. In the western hemisphere, its main use is for aircraft beacon, navigation (LORAN), information, and weather systems. A number of time signal broadcasts also use this band. Propagation Because of their long wavelength, low frequency radio waves can diffract over obstacles like mountain ranges and travel beyond the horizon, following the contour of the Earth. This mode of propagation, called ''ground wave'', is the main mode in the LF band. Ground waves must be vertically polarized (the electric field is vertical while the mag ...

Balanced Audio
Balanced audio is a method of interconnecting audio equipment using balanced interfaces. This type of connection is very important in sound recording and production because it allows the use of long cables while reducing susceptibility to external noise caused by electromagnetic interference. The balanced interface guarantees that induced noise appears as common-mode voltages at the receiver which can be rejected by a differential device. Balanced connections typically use shielded twisted-pair cable and three-conductor connectors. The connectors are usually three-pin XLR or TRS phone connectors. When used in this manner, each cable carries one channel, therefore stereo audio (for example) would require two of them. Applications Many microphones operate at low voltage levels and some with high output impedance (hi-Z), which makes long microphone cables especially susceptible to electromagnetic interference. Microphone interconnections are therefore a common application for a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
