Microphone Connector
Many different electrical connectors have been used to connect microphones to audio equipment—including PA systems, radios, tape recorders, and numerous other devices. Phone connectors Photo: 2.5 mm mono (TS), 3.5 mm mono and stereo (TRS), and 1/4″ (6.35 mm) stereo (TRS) phone connectors The most common microphone connector in consumer use is the venerable phone connector, in 1/4" (6.35 mm), 3.5 mm, and 2.5 mm sizes, and in both mono and stereo configurations. Not all microphone plugs with 3-segment TRS (Tip-Ring-Sleeve) connectors are actually stereo. Most computer microphones use the third segment to carry bias power for the microphone. Type "O" 1930s connectors These round connectors are about 1 inch in diameter. They were in common use in the later 40's and thru the 50's at WELI, New Haven Connecticut. see: http://terryking.us/OldRadio/OP-4-RCA-RemoteAmplifier-1934-Rear.jpg The 3 connectors on the left are 1934 type "P" round micropho ...

Phone Connector (audio)
A phone connector, also known as phone jack, audio jack, headphone jack or jack plug, is a family of electrical connectors typically used for analog signal, analog audio signals. A plug, the Gender of connectors and fasteners, male connector, is inserted into the jack, the female connector. The phone connector was invented for use in telephone switchboards in the 19th century and is still widely used. The phone connector is cylindrical in shape, with a grooved tip to retain it. In its original audio configuration, it typically has two, three, four or, occasionally, five contacts. Three-contact versions are known as ''TRS connectors'', where ''T'' stands for Tip and ring, "tip", ''R'' stands for Tip and ring, "ring" and ''S'' stands for "sleeve". Ring contacts are typically the same diameter as the sleeve, the long shank. Similarly, two-, four- and five-contact versions are called ''TS'', ''TRRS'' and ''TRRRS connectors'' respectively. The outside diameter of the "sleeve" c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

XLR Connector
The XLR connector is a type of electrical connector primarily used in professional audio, video, and stage lighting equipment. XLR connectors are cylindical in design, and have three to seven connector pins, and are often employed for analog balanced audio interconnections, AES3 digital audio, portable intercom, DMX512 lighting control, and for low-voltage power supply. XLR connectors are included to the international standard for dimensions, IEC 61076-2-103. The XLR connector is superficially similar to the smaller DIN connector, with which it is physically incompatible. History and manufacturers The XLR connector (also Cannon plug and Cannon connector) was invented by James H. Cannon, founder of the Cannon Electric company, Los Angeles, California. The XLR connector originated from the ''Cannon X'' series of connectors in 1915; by 1950, a latching mechanism was added to the connector, which produced the ''Cannon XL'' model of connector, and by 1955, the female connector ...

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] |
Clear-Com
Clear-Com, also known as ClearCom, is a manufacturer of electronic intercom products, widely used to enable stage management and crew communications in theatre, filmmaking, video and television production, concerts, professional sports competitions, special events and audiovisual presentations. Providing the first portable party-line intercom system to feature simple XLR cable connections, Clear-Com soon became an accepted industry standard. The National Academy of Television Arts & Sciences honored the company with a Technology and Engineering Emmy Award in 2010. Clear-Com was founded in San Francisco, California, on April 18, 1968, by audio engineer Charlie Butten and his business partner Bob Cohen, a sound company owner who had recently been part of Family Dog Productions organizing dance concerts at the Avalon Ballroom. The first Clear-Com product was the RS-100 intercom station, a portable unit connected using standard XLR-terminated microphone cables. The connection scheme ...

DIN Connector
The DIN connector is an electrical connector that was standardized by the ' (DIN), the German Institute for Standards, in the early 1970s. The male DIN connectors (plugs) feature a 13.2 mm diameter metal shield with a notch that limits the orientation in which plug and socket can mate. The range of DIN connectors, different only in the configuration of the pins, have been standardized as DIN 41524 / IEC/DIN EN 60130-9 (3-pin at 90° and 5-pin at 45°); DIN 45322 (5-pin and 6-pin at 60°); DIN 45329 / IEC/DIN EN 60130–9 (7-pin at 45°); and DIN 45326 / IEC/DIN EN 60130-9 (8-pin at 45°). In consumer electronics, the term "DIN connector" identifies types of cylindrical connectors that the German Institute for Standards (DIN) had initially standardised for analog audio signals. Some DIN connectors have been used in analog video applications, for power connections, and for digital interfaces, such as the MIDI (DIN 41524), the IBM PC keyboard and the IBM AT keyboard connect ...

Citizens Band Radio
Citizens band radio (also known as CB radio), used in many countries, is a land mobile radio system, a system allowing short-distance person-to-many persons bidirectional voice communication among individuals, using two way radios operating on 40 channels near 27 MHz (11 m) in the high frequency (a.k.a. shortwave) band. Citizens band is distinct from other personal radio service allocations such as FRS, GMRS, MURS, UHF CB and the Amateur Radio Service ( "ham" radio). In many countries, CB operation does not require a license, and (unlike amateur radio) it may be used for business or personal communications. Like many other land mobile radio services, multiple radios in a local area share a single frequency channel, but only one can transmit at a time. The radio is normally in receive mode to receive transmissions of other radios on the channel; when users want to talk they press a " push to talk" button on their radio, which turns on their transmitter. Users ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amateur Radio
Amateur radio, also known as ham radio, is the use of the radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communications. The term "amateur" is used to specify "a duly authorised person interested in radioelectric practice with a purely personal aim and without pecuniary interest;" (either direct monetary or other similar reward) and to differentiate it from commercial broadcasting, public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.). The amateur radio service (''amateur service'' and '' amateur-satellite service'') is established by the International Telecommunication Union (ITU) through the Radio Regulations. National governments regulate technical and operational characteristics of transmissions and issue individual station licenses with a unique identifying call sign, which mus ...
