  2. Phantom power - Wikipedia

    en.wikipedia.org/wiki/Phantom_Power

    Phantom power is sometimes used by workers in avionics to describe the DC bias voltage used to power aviation microphones, which use a lower voltage than professional audio microphones. Phantom power used in this context is 8–16 volts DC in series with a 470 ohm (nominal) resistor as specified in RTCA Inc. standard DO-214. [19]

  3. Microphone - Wikipedia

    en.wikipedia.org/wiki/Microphone

    Since the 1980s, phantom power has become much more common, because the same input may be used for both powered and unpowered microphones. In consumer electronics such as DSLRs and camcorders, "plug-in power" is more common, for microphones using a 3.5 mm phone plug connector. Phantom, T-power and plug-in power are described in international ...

    en.wikipedia.org/wiki/Shure_SM58

    Other suffixes refer to any accessories supplied with the microphone: when a cable is provided, the model is actually SM58-CN, while the SM58-LC has no provided cable (LC means Less Cable); the SM58-X2u kit consists of the SM58-LC and an inline X2u XLR-to-USB signal adaptor (capable of providing phantom power for condenser microphones, and ...

  5. Electret microphone - Wikipedia

    en.wikipedia.org/wiki/Electret_microphone

    Electret microphones require no polarizing voltage unlike other condenser microphones, but normally contain an integrated preamplifier which requires a small amount of power (often incorrectly called polarizing power or bias). This preamp is frequently phantom powered in sound reinforcement and studio applications. Other types include a 1.5 V ...

  6. Wireless microphone - Wikipedia

    en.wikipedia.org/wiki/Wireless_microphone

    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 ...

  7. XLR connector - Wikipedia

    en.wikipedia.org/wiki/XLR_connector

    Phantom power is usually supplied at a nominal 48 volts DC, although lower voltages are permissible and modern microphones will often operate over a wide range. It is common for modern mixers to have a built-in switch-operated 48-volt power supply which supplies all mic inputs with phantom power, thus eliminating the need for bulky external ...

  8. Boundary microphone - Wikipedia

    en.wikipedia.org/wiki/Boundary_microphone

    A Crown Audio brand PZM, the "Sound Grabber II". It is shown with adapters to enable it to be connected to different mixers and audio devices. The mic has an internal battery so that it can be used with consumer audio devices that do not supply phantom power. Boundary mics may have XLR or 1/4" TRS jacks. Some use mini-XLR or 1/8" TRS jacks.

  9. Neumann U 87 - Wikipedia

    en.wikipedia.org/wiki/Neumann_U_87

    Neumann U 87 with shock mount. Introduced in 1967 as the solid-state successor to the U 67, [4] [5] [1] Neumann introduced the U 87 alongside the KM 86, KM 84, and KM 83 as part of the company's first 'FET 80' series of microphones that utilized use solid-state FET electronics that didn't require separate power supplies or multi-pin power cables and allowed the mics to be made smaller.
