Phantom power, in the context of professional audio equipment, is DC electric power equally applied to both signal wires in balanced microphone cables, forming a phantom circuit, to operate microphones that contain active electronic circuitry. [ 1] It is best known as a convenient power source for condenser microphones, though many active ...
Reference designator. A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board. The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15. The number is sometimes followed by a letter, indicating that components are ...
Electronic symbol. An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may vary from country to country ...
Ground lift. In sound recording and reproduction, ground lift or earth lift is a technique used to reduce or eliminate ground -related noise arising from ground loops in audio cables. It may also increase or decrease noise from other sources. [1] Activating the ground lift on a particular piece of equipment opens the connection between the ...
Phantom circuit. In telecommunication and electrical engineering, a phantom circuit is an electrical circuit derived from suitably arranged wires with one or more conductive paths being a circuit in itself and at the same time acting as one conductor of another circuit.
A ribbon microphone, also known as a ribbon velocity microphone, is a type of microphone that uses a thin aluminum, duraluminum or nanofilm of electrically conductive ribbon placed between the poles of a magnet to produce a voltage by electromagnetic induction. Ribbon microphones are typically bidirectional, meaning that they pick up sounds ...
Star quad cable. Star-quad cable intended for use with a single two-wire circuit or two two-wire circuits. It is often used with microphone signals in professional audio. Star-quad exploded view showing the geometric centers of the dual-conductors used for each leg of the balanced line. To achieve magnetic immunity, geometric centers of both ...
XLR3 cable connectors female (left) and male. The XLR connector is a type of electrical connector primarily used in professional audio, video, and stage lighting equipment. XLR connectors are cylindrical, with 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 ...
