Phantom powered microphone systems use a 3 pin XLR connector. A phantom powered microphone sys- tem should use a 48V phantom power supply or signal conditioner for optimum performance; however these microphone systems may be powered with a 24V or a 12V phantom power supply, but this will lim- it the maximum output voltage.
The lowest amplitude a healthy human ear can detect is 20 millionths of a Pascal (20Pa). Another scale more commonly used to describe sound pressure level is the decibel (dB). To convert the output voltage signal (measured in Vrms) to sound pressure level (measured in decibels), use the following formula: ...
Clamps and stands When holding a microphone in place, it is important to minimize the influence of the stand on the sound being measured. This can be accomplished by using low profile stands and clamps available from PCB. Cables and Electronics ...
