Flashcards in test 2 Deck (30):
1

What is the primary difference between capacitor and moving coil (dynamic) microphones?

Capacitor microphones need power to operate; Moving coil need magnetic variations to operate

2

List at least (3) characteristics of a Ribbon microphone:

More fragile, more expensive, more sensitive, small output level, can't take high SPL levels, noisy in distant miking situations, sounds good

3

On a capacitor microphone, there sometimes exists (2) switches (other than the pattern
switch) to give the sound engineer more flexibility with the sound. What are these (2)
switches and how are they used?

-10dB pad to reduce input level and control distortion at the preamp; Bass roll-off, usually at about 80Hz to control proximity effect.

4

A microphone’s directional sensitivity is also known as what?

polar response pattern

5

Describe the sensitivity or polar response of omnidirectional, bi-directional, and cardioid
microphones.

Omnidirectional- sound is picked up almonst uniformly in all directions; Bi-directional- figure eight pattern, sound is picked up from the front and rear of the mic and least sensitive on the sides; Cardioid- most sensitive at the front and front sides.

6

Describe a microphone’s frequency response.

The range of frequencies that it produces at an equal level, within a margin of +3dB.

7

In what year did the Neumann Company begin manufacturing condenser microphones?

1928

8

What happens to a microphone’s sensitivity with regard to frequency?

The higher the frequency, the more directional a mic becomes. The lower the frequencey, the less directional it becomes regardless of its pickup pattern.

9

Capacitor microphones are very sensitive. Name some accessories commonly used with
capacitor microphones to aid in the recording process

Windscreen, pop filter, shock mounts.

10

When was the first cardioid capsule microphone made and who made it?

1932, Neumann

11

When checking to see if a microphone is ‘on’, what’s the first thing you Shouldn’t do?

Blow into it

12

What type of acoustic treatment would I use to obtain a more uniform distribution of
sound?

diffusion

13

What type of acoustic treatment would I use to obtain a more uniform distribution of
sound?

diffusion

14

Give me (3) important points to consider in Control room/studio design.

Ergonomics-sight lines, access, first reflections, noise, isolation, lighting, size

15

When choosing a studio for a project, what is the first consideration?

the music style

16

What type of microphone would a TV news anchor use for broadcast?

lavalier

17

What types of microphones work best with violins, violas, and cellos?

capacitor and ribbon

18

Name the (3) types of stereo micing techniques that we learned.

Coincident pair(XY); Near Coincident pair; Spaced.

19

What type of micing technique is generally used for drums in rock or pop music?

close mic'ing

20

What type of micing technique is best for lousy drums and a lousy drummer?

trick question, there is none

21

What is the ORTF array, what does it stand for and how are the mics placed?

Office de Radiodiffusion-Television Francaise. Two cardioid microphones on a single stand spaced just under 7 inches apart at a 110º angle.

22

List at least (3) ways to increase stereo imaging.

Bringing microphones closer to their respective sources; using acoustic barriers; utilizing directional mics; spreading sound sources farther apart.

23

What microphone technique is most used in recording film scores?

The Decca Tree

24

Close microphone techniques are generally used to:

maintain the relative position of an instrument within an ensemble.

25

Explain the 3 to 1 micing rule and why is it important?

No two microphones closer together than three time the distance between one of them and the sound source. Minimizes phasing problems.

26

I’m trying to record my acoustic guitar and it sounds ‘thin and lifeless’. What should I do
to achieve a warm, more full-bodied sound?

Use a large diaphragm capacitor microphone about one to three feet from the sound hole.

27

Microphone selection and positioning depend on what factors?

The type of music, the musician, the quality of the instrument, the acoustics, the number of musicians.

28

What are the (2) methods of recording electric instruments?

Miking the amplifier or direct insertion.

29

Prior to listening to an instrument or voice in the control room, what’s the first rule in
microphone selection and positioning?

Listen to the instrument or voice in the room first.

30

Describe a ‘transient’.

Sounds that begin with a fast attack and then a quickly decay.
