Question 8

how to record read a newer ATR

Answer 8

select track under “Ready” and hit record

Question 9

3 magnetic tape heads

Answer 9

record head records
reproduce head playback
erase head

Question 10

3 monitoring modes

Answer 10

input monitoring
reproduce mode
select synchronization

Question 11

common tape speeds

Answer 11

7.5, 15, 30

Question 12

effects of print-through

Answer 12

audio seeps through tape because it wasn’t stored properly

Question 13

how to prevent print-through

Answer 13

tails-out storage, where backing is on top, oxidized (data storing part is below)

Question 14

how wide was tape

Answer 14

quarter inch to 2 inches

Question 15

ATR signal flow now

Answer 15

mic to tape machine to DAW

Question 16

disadvantages

Answer 16

punches had to be super precise and well-rehearsed, cutting and pasting is difficult

Question 17

ATR

Answer 17

analog tape recorder

Question 18

3 ways to reduce leakage

Answer 18

build massive, solid structure
eliminate joints, which easily transmit sound through barrier
dampen structures so walls are reinforced

Question 19

what is leakage

Answer 19

resonance and sound from elsewhere

Question 20

what is a soffit

Answer 20

cavity on front-facing wall in control room to mount monitors to wall to reduce reflections and resonances in control room

Question 21

common practice for isolating floor-related noise

Answer 21

hockey puck iso mounts, or U-Boat float floats, or continuous underlay like rubber floor mat

Question 22

why use double doors?

Answer 22

they form acoustical sound lock, reduces leakage because of air between the 2 solid barriers

Question 23

what is an iso booth?

Answer 23

iso-room acoustically isolated/sealed area built to keep the louder instruments from the softer instruments

Question 24

gobo?

Answer 24

acoustic partition, provides on-the-spot barriers to sound leakage

Question 25

symmetry in control room and the sweet spot

Answer 25

the sweet spot is within the equilateral triangle, your ears must be equidistant to the speakers

Question 26

standing waves also called

Answer 26

room nodes

Question 27

standing waves are from

Answer 27

parallel walls

Question 28

standing wave is

Answer 28

when sound wave is reflected and travels back on its own path, causing phase differences which interfere with the room’s frequency response

Question 29

magnetization and the erase head

Answer 29

high magnitude, high frequency AC current erases previous recorded signal

Question 30

reproduce head

Answer 30

converts magnet pattern on tape to electrical signal

Question 31

tape passes over ___ head before record head

Answer 31

erase head

Question 32

input monitoring

Answer 32

listen to source

Question 33

reproduce mode

Answer 33

(monitoring) listen to what was recorded

Question 34

select synchronization

Answer 34

(monitoring) for overdubbing - plays back all tracks but arms what you want to record
