has a diaphragm that is
directly connected to a core of wire called the
"voice coil" that is suspended in a magnetic field
The movement of the diaphragm causes the
voice coil to move in the magnetic field and thus
creates an electrical signal that's proportional to
the acoustical pressure waves from the source
that you are recording.
 Use electrostatic properties, and
consists of two thin plates, one
moveable and one fixed, that form a
capacitor.
 The moveable plate moves in relation
to the acoustical pressure waves, the
capacitance is changed between the
plates, and the voltage across the
plates will change in proportion.
Can react even quicker and often have even
better high frequency response, but at the sacrifice
of the low end warmth... The smaller condensers are
usually used for acoustic guitars and
overheads/cymbals for drums, because you usually
want a lot of high-end detail with very quick
transient response for these types of sources, and
you don't care as much about the low end.
Are usually associated with being warmer
and bigger sounding, and thus are quite
popular for vocals or solo instrument work.
• Dynamic Microphone
• Work well in live sound situations because they don't
tend to cause feedback problems as much as
condensers do (although a lot of this has to do with the
pickup patterns used and the placement of the mics and
the room acoustics).
• Can usually handle much sound pressure level than
condensers (although today's condensers can handle
much more) and usually work better for percussive
sources (close mic'ing drum kits) or really loud sources
(close mic'ing guitar cabinets)
•
They are a lot more durable and can handle a lot more
abuse than a condenser microphone as well
• Condenser microphones require an external power
source (phantom power) while dynamic microphones
do not.
•
• Condenser Mic
-Are usually preferred for sources where you want more of that
brighter, yet clear and detailed high frequency sound, such as vocals,
acoustic guitars, piano, drum overheads or room mics, etc
- Condenser microphones are easy to miniaturize, while dynamic
microphones cannot be miniaturized.
- Condenser microphones' frequency response tends to be uniform,
while dynamic microphones' typically is not.
- Good for vocal or instrumental reinforcement and recording
- High sensitivity and extended high frequency response
- When it comes to picking up high frequency or low amplitude signals,
condenser mikes are the answer. Dynamic mikes just aren't sensitive
enough.
• Due to the fact that dynamic
microphones depend on air pressure
moving the large mass of the coil, they
tend to lose light delicate sounds.
• Dynamic microphones are not usually
expected to reproduce the sounds very
faithfully.
