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]
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 ...
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 ...
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 ...
DI boxes which require a power source (batteries or phantom power) are called active DI boxes. A DI unit (direct input or direct inject) is an electronic device typically used in recording studios and in sound reinforcement systems to connect a high output impedance unbalanced output signal to a low-impedance, microphone level, balanced input ...
The third-quarter pass secured the first Titans touchdown of the day. The Vikings blitzed five pass rushers on third-and-10. But Tennessee's offensive line stood its ground to buy Levis time as he ...
The Big Ten and Southeastern Conference both have arguments to be considered the top league in women's basketball. Each has seven teams ranked in The Associated Press Top 25 women's basketball ...
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 ...
