AMP connector. In 1941, Aircraft and Marine Products (AMP) was founded with electrical connections lacking solder for quick and removable wire connection used for aircraft and ships. After the war time boom, the company had to adapt to the post-war economy, and in 1956, the name of the company was changed to AMP Incorporated when it incorporated.
Guitar wiring refers to the electrical components, and interconnections thereof, inside an electric guitar (and, by extension, other electric instruments like the bass guitar or mandolin). It most commonly consists of pickups , potentiometers to adjust volume and tone, a switch to select between different pickups (if the instrument has more ...
Bottom: bi-wiring. Loudspeaker bi-wired using banana plugs. Bi-wiring is a means of connecting a loudspeaker to an audio amplifier, primarily used in hi-fi systems. Normally, there is one pair of connectors on a loudspeaker and a single cable (two conductors) runs from the amplifier output to the terminals at the loudspeaker housing.
To allow the construction of hybrid systems, where the 4–20 mA is generated by the controller, but allows the use of pneumatic valves, a range of current to pressure (I to P) converters are available from manufacturers. These are usually local to the control valve and convert 4–20 mA to 3–15 psi (or 0.2–1.0 bar).
An (orange-epoxy) encapsulated hybrid circuit on a printed circuit board (PCB).. A hybrid integrated circuit (HIC), hybrid microcircuit, hybrid circuit or simply hybrid is a miniaturized electronic circuit constructed of individual devices, such as semiconductor devices (e.g. transistors, diodes or monolithic ICs) and passive components (e.g. resistors, inductors, transformers, and capacitors ...
A hybrid coil accomplishes the conversion for both. At the central office, it is part of a four-wire terminating set, more often as part of a line card. A modern line card has no two-to-four wire conversion whatsoever; it is strictly an analog/digital interface to a system that has a completely digital and integrated signal path internally.
Example: The image shows two identical amplifiers A1 and A2 connected in bridge mode. The system is arranged in such a way that the outputs from the amplifiers are inverted with respect to each other. In other words, as the signal in one amplifier is swinging positively, the signal in the other is swinging negatively.
Mesa-Boogie Mark IV, a guitar combo amplifier. A guitar amplifier (or amp) is an electronic device or system that strengthens the electrical signal from a pickup on an electric guitar, bass guitar, or acoustic guitar so that it can produce sound through one or more loudspeakers, which are typically housed in a wooden cabinet.
