.jpg "Choosing A Microphone") Choosing a Microphone can be a confusing decision. This article was created in hope to help clear things up about the different types of microphones, how they work, and what they are typically used for.
Dynamic Microphones
Dynamic Microphones from
a technical aspect operate on the electromagnetic principle, just like
the electromechanical loudspeaker. Dynamic microphones are mainly used
when working with a loud sound source that doesn't contain a lot of
high frequency detail, because typically, Dynamic microphones tend to
accent the middle of the frequency spectrum. Dynamic microphones are
seen primarily in live situations where moisture and other factors come
into place. No pre-amplifier is needed for this type of microphones.
Condenser Microphones
The
condenser microphone, technically, is an electrical system that depends
upon variations in the internal capacitance. Condenser microphones
require power supply, typically phantom power or a small battery. They
are used primarily in studio recording because they are known for their
all around frequency response.
Electret Condenser Microphones
In
the microphone world, the electret condenser microphone is a relatively
new microphone (circa 1962). It works similar to the condenser
microphone, but the condenser plate is made from an electret material
to provide the polarizing voltage. They don't require phantom power to
charge the diaphragm (like the condenser), however they do require a
power supply for their in-microphone preamplifier.
Ribbon Microphones
The
Ribbon Microphone (also referred to as a "velocity" microphone) is a
type of dynamic microphone that uses a thin metal ribbon placed between
the poles of a magnet and generate voltages by electromagnetic
induction. Ribbon mics do not require phantom power, which if enabled,
actually can destroy this type of microphone. Ribbon microphones are
generally the most delicate and expensive microphone because they are
known for their ability to capture fine high-frequency detail.
