Condenser microphone
Definition and instrument use:
The use of this microphone is for singing
and instrument recording
Advantages:
-This allows the audio signal to be stronger than a
dynamic microphone.
-A condenser microphone can respond extremely
fast.
Disadvantages:
-The voltage within the microphone will have to be
consistently maintained.
Dynamic microphone
Definition and instrument use:
Dynamic microphones are ideal for general- purpose use. They
use a simple design with a few moving parts. the sound waves
cause a moveable wire or coil to vibrate in a magnetic field and
therefore induces a current.
Advantages:
They have the ability to withstand high sound pressure levels, for
loud drums, guitar amps and live vocals.
Disadvantages:
Reduce accuracy compared to other types of microphones.
- The output current in the microphone is also very low and
therefore requires a lot of amplification.
Polar Patterns / Directional response in
Microphones
Definition and instrument use:
A cardioid microphone has the most sensitivity
at the front and is least sensitive at the back.
Advantages:
Suitable for loud stages.
Disadvantages:
Omnidirectional microphones can not be
aimed away from undesired sources.
Microphones with Phantom Power
Definition and instrument use:
Phantom power is a method for transmitting
DC electric power through microphone cables
to operate microphones that contain active
electronic circuitry.
Advantages:
Much wider rage of microphones to choose
from, as only a small fraction have internal
battery option.
Disadvantages:
If you are using battery-operated equipment,
it will use batteries at a significantly higher
rate.
Proximity effect of Microphones
Definition and instrument use:
The proximity effect in audio is an increase in
base or low frequency response when the
sound source is close to the microphone.
Advantages:
Proximity affect can add fullness to the sound
Disadvantages:
But in excess it can also contribute to
‘muddiness’ or ‘boominess’ of sound quality.
Frequency response of microphones
Definition and instrument use:
Frequency response refers to the way a
microphone responds to different frequencies.
It is a characteristic of all microphones that’s
some frequencies are exaggerated and others
are reduced.
Advantages:
They are less susceptible to picking up noise
and rumbles from mechanical vibrations.
Disadvantages:
Problems in frequency are mostly encountered
with sounds originating from behind the
microphone.
Actor
How will a microphone make life harder for
the performer/audience. Yes
Because the performer will have to move
there arms and therefore a head piece
would be needed .
frequency
(low/high frequencies or a mixture)
Mixture
input
(will the volume remain the same?)
It would be a mixture of voices.
Group of singers
How will a microphone make life harder for the
performer/audience.
Yes because the microphone would not catch everyone's
voice.
frequency
(low/high frequencies or a mixture)
Mixture of voice’s
input
(will the volume remain the same?)
No Because you have different people singing at different
volumes.
Amplifier(gtr/keys)
How will a microphone make life
harder for the performer/audience.
The amplifier might make the
performers voice obscure or
illegible.
frequency
(low/high frequencies or a mixture)
mixture
input
(will the volume remain the same?)
No as the performers pitch or tone
may change.
Snare drum
How will a microphone make life harder
for the performer/audience.
The microphone might be nocked over by
the drum kit due to the force that the
drum kit is being played at.
frequency
(low/high frequencies or a mixture)
mixture
input
(will the volume remain the same?)
Mixture because people will hit the drum
at various pitches.
Drum kit
How will a microphone make life
harder for the performer/audience.
You may need more then one
microphone resulting in a much more
complex set up.
frequency
(low/high frequencies or a mixture)
mixture
input
(will the volume remain the same?)
It will be a mixture due to the
amount of sounds being made e.g
symbol may be louder then the
drums.
Solo singer
The best microphone?
SM58 vocals microphone.
Why this microphone?
The microphone delivers warm clear vocal
reproduction favoured by performers world
wide.
What other Microphones did you consider and
why did you not use them?
The Super 55 as it is suited specifically to vocal
applications. Therefore, typically live
performance, public address as well as for
broadcasting. It however did not seem
favoured by most performers.
Group of singers
The best microphone?
The SM94
Why this microphone?
The SM94 is flat-response microphone
for live performance and useful
picking up remote recordings. This
would therefore allow individual
voices within the choir to be picked
up.
What other Microphones did you
consider and why did you not use
them?
The SM137 as despite producing a
natural sound in acoustic and high
volume performances it did not pick
up individual voices as accurately.
Amplifier
The best microphone?
Sennheiser E865 Microphone
Why this microphone?
Because It is great for the amp as its
distortion free.
What other Microphones did you consider
and why did you not use them?
Shure PG81 Overhead Cardioid Condenser
Microphone allows a precise and smooth
capture of subtle characteristics from each
sound source.
Kick drum
The best microphone?
Shure Beta 57A Microphone
Why this microphone?
Recommended applications
include kick drum.
What other Microphones did
you consider and why did you
not use them?
Sontronics DM1B
Snare drum
The best microphone?
Shure PG56-XLR
Why this microphone?
Shure PG 56-XLR - dynamic
instrumental microphone for snare,
toms & percussion. Cardioid pattern.
What other Microphones did you
consider and why did you not use
them?
Audio-Technica ATM350
TASK 2:
Head to the studio and set up the mics ready
to record. TAKE PHOTOS!!!
These are my final pictures
and recordings
