Q

frequency response

A

how well mics pick up various frequencies

17
Q

most common polar pattern

A

cardioid

18
Q

ribbons mics are mostly what polar pattern

A

bi-directional

19
Q

how do you counter proximity effect?

A

turn mic off access

20
Q

how do you mic pop?

A

close

21
Q

how do you mic an orchestra?

A

distance (get both room and source)

22
Q

ambient micing mics what?

A

just room, no direct source

23
Q

3:1 rule

A

for every 1 foot the mic is from the source, it must be 3 feet away from the next mic

24
Q

bleed

A

initial source + picking up unintended instruments

25
Q

adding multiple mics increases the risk for

A

phase shift

26
Q

DI

A

direct input

27
Q

why DI?

A

no leakage, line level source is balanced, change output level and eliminate electrical humming

28
Q

space pair

A

equidistant from source

29
Q

to get more mono with a space pair

A

put the mics close

30
Q

to get more stereo with a space pair

A

put the mics further back

31
Q

XY pair

A

cross-mic with cardioid

32
Q

blumlein

A

XY with bidirectional

33
Q

decca tree (type and placement)

A

cardioid middle, omni sides

34
Q

decca tree is for micing what?

A

recital

35
Q

fix phase problems in mix

A

copy side channel and invert phase
