Microphone Techniques Flashcards
dynamic transducer
wire coil
ribbon transducer
thin corrugated metal diaphragm
condenser transducer
2 plates
what requires phantom power?
condenser
omni
all around
cardioid
front and sides, not behind
super cardioid
heart with tear drop
hyper cardioid
heart with fat tear drop
bi-directional
figure 8
proximity effect
more low-end when you are closer
mic with highest transient response
condenser
why are XLR cables balanced?
3 pins: + - ground
quarter inch balanced?
no if 1 ring, yes if 2 rings
ground is also called
shield
pre-amps do what?
boost signal
frequency response
how well mics pick up various frequencies
most common polar pattern
cardioid
ribbons mics are mostly what polar pattern
bi-directional
how do you counter proximity effect?
turn mic off access
how do you mic pop?
close
how do you mic an orchestra?
distance (get both room and source)
ambient micing mics what?
just room, no direct source
3:1 rule
for every 1 foot the mic is from the source, it must be 3 feet away from the next mic
bleed
initial source + picking up unintended instruments
adding multiple mics increases the risk for
phase shift
DI
direct input
why DI?
no leakage, line level source is balanced, change output level and eliminate electrical humming
space pair
equidistant from source
to get more mono with a space pair
put the mics close
to get more stereo with a space pair
put the mics further back
XY pair
cross-mic with cardioid
blumlein
XY with bidirectional
decca tree (type and placement)
cardioid middle, omni sides
decca tree is for micing what?
recital
fix phase problems in mix
copy side channel and invert phase
