Modulation Noise
|
High Frequency Noise due to uneven coating on tape.
|
|
|
What are two ways to reduce noise?
|
Hit the MTR harder; Control the dynamic range
|
|
|
what are the three types of automation systems?
|
tape based; disk based; mechanical fader
|
|
|
3 modes of automation
(tape and disk based) |
1) write- records null points. control voltage must be present. parameters are start and stop time.
2) update- updates the null points. creates new null point for each subframe in timecode 3) read- can not automate. can only review what's already been automated. |
|
|
rollback point
|
when rewinding, this point is created. after passing rollback point, you go from read to update.
|
|
|
statuses (are local)
|
1) write
2) update 3) revise cuts (places cuts into write mode) |
|
|
Mechanical fader modes
|
1) record- write and playback previously written autmation
2) safe- can't write new info. plays back previously written info. 3) isolate- can't write new information. won't playback previously written information. allows you to temporarily or permenantly remove something from automation |
|
|
2 things to do when automating mechanical faders:
|
check rsi to make sure it is in record mode.
make sure the ram is empty |
|
|
mechanical fader statuses
|
1)touch- default status of record
2) lock- overwrites fader automation 3) automatch- fader will return to its nill point within one frame. this is refered to as glide time. |
|
|
mechanical fader mute statuses
|
record mode status is add. stopping machine goes to add.
|
|
|
compansion is
|
upward compression. downward expansion.
|
|
|
coincident pairs:
|
xy, blumlein array, and ms.
|
|
|
kx pattern
|
distance equates to ambience and width of image. mono compatible.
|
|
|
exaggerated separation
|
in any instrument is 15dB or louder then any other instrument, it will be heard in the extreme outside edge of the image.
|
|
|
blumlein array
|
two bidirectional mics stacked one on top of the other.
|
|
|
mid side
|
uses biditectional and cardiod mic.
on bidirectional, go from mic lines into the mult to double |
|
|
another name for single ended noise reduction
|
non- complimentary
|
|
|
dbx's fixed compression ratio
|
2:1
|
|
|
what does sr use to reduce noise?
|
fixed gain, fixed frequency
|
|
|
how man paird of fixed sliding bands on sr
|
5; cross linked known as action substitution
|
|
|
type a
|
reduces noise below 5K by 10dB.
reduces program noise by 4 bands manually calibrated- 400 & 700 hZ |
