Popular microphone connector from 1930s to 1980s, originally manufactured by Amphenol. Amphenol sold this production to WPI Interconnect in early 1980s. The Amphenol 80-MC2M, which mates with the 80-PC2F, microphone connector was popular with American radio manufacturers (1950s to 1970s). The Amphenol 80-PC2F connector, that mates with the 80-MC2M
While the above discussion focuses on preventing noise from getting in (e.g. into a microphone cable) the same star-quad quadrupole configuration is useful for audio speaker cable, [11] for split-phase electric power wiring, and even for open-wire star quad transmission line. In these cases, the purpose of the star quad configuration is reversed.
Typical live use of a multicore (thick cable on stage) Multicores usually create a link between the stage and sound desk, or live room and control room.When used in sound reinforcement, the multicore cable runs from the stage box or microphone splitter to the front-of-house sound desk, where it connects to a mixing console.

The transient generated when a microphone is hot-plugged into an input with active phantom power can damage the microphone and possibly the preamp circuit of the input [10] because not all pins of the microphone connector make contact at the same time, and there is an instant when current can flow to charge the capacitance of the cable from one ...
An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...
Two examples of different boundary mics (top) and a diagram of the elements of a boundary microphone. The diagram shows the location of the mic capsule, the plate, the aperture, and the pressure zone. In 1978, audio engineers Ed Long and Ron Wickersham studied the effects of the boundary layer in sound recording.
The microphone generates its own voltage and needs no power. Devices that use a self-powered microphone: usually a condenser microphone with an internal battery-powered amplifier. Devices that use a plug-in powered microphone: an electret microphone containing an internal FET amplifier. These provide a good quality signal in a very small ...
A wireless microphone, or cordless microphone, is a microphone without a physical cable connecting it directly to the sound recording or amplifying equipment with which it is associated. Also known as a radio microphone , it has a small, battery-powered radio transmitter in the microphone body, which transmits the audio signal from the ...
