Microphone type (dynamic or condenser)
when selecting the microphones that you

will use there are several variables: these
microphone size and stands
variables include
microphone cost
dynamic, condenser, or a combination of dynamic and condenser microphones.
for the purpose of digital reporting, AAERT
Both of these microphone types work in a unique way but can generate a high

quality audio reproduction
(also called "moving coil" microphones) are made up of a diaphragm, a coil, and a
magnet. As acoustical energy hits against the diaphragm, which is a flat plate at the
dynamic microphones
front of the microphone, it causes the coil that is attached to it to move back and
forth over top of the magnet . they are bulky
consists of a front plate (diaphragm), back plate, and a 48 volt power source. The
condenser microphone front and back plate together create a capacitor. wider assortment of shapes and
sizes. one type commonly used is a gooseneck microphone

, when acoustical energy hits the front plate of the capacitor, the distance between
the front and back plate changes. the gap between these two plates is electrically

the use of batteries as the supply of this charge. if a battery would die during use,
aaert does not recommend: you could have a gap in your recording and you would need to interrupt the event

act as a phantom power supply source. the changes in electrical energy between
these two plates will travel through the wires of the microphone and eventually
reach your digital mixer or A/D converter. essentially the biggest difference between
most digital mixers and A/D converters these microphone types is the way by which acoustical energy is transformed into
electrical energy: one assisted by an electrical source and the other by a magnet.
both are capable of facilitating a quality audio recording and are recommended for
use in the field of digital reporting
pick-up pattern is the set path in which a microphone will intercept sound
(also known as unidirectional) meaning heart shaped, is a heart shaped pattern
which reaches out from the diaphragm of a microphone. This pick-up pattern is
cardioid pick-up pattern
beneficial for capturing a SINGLE voice located in front of a microphone while
rejecting additional ambient room sound
is the combination of the word omni meaning "ALL" and direction. It intercepts sound
omnidirectional pick-up pattern from all directions from its placement. meaning it captures sound equally from all
directions. Its beneficial for capturing multiple voices using only one microphone
these microphones lay flat on a desk or table and are commonly no more than inch

this is an extremely small condenser microphone that attaches directly to the
