Playback signal envelope level read-out value averaged for each
|
track of each head
255
ENV L: Lch head
ENV R: Rch head
Averaging is performed at 8 points in the track, and the newest track
value for which averaging has been completed at the time when
read-out is started will be read out.
• Read-out is possible only at the time of PLAY and REC.
0
• The value is held until exit from PRO ADJUST, DV ADJUST.

Operation:
• At the time of C32, D32: IC READ = SINGLE
Read-out and display are performed each time the SET
button is pressed.
• At the time of C32, D32: IC READ = CONT
Read-out and display are performed once every second.
0
The control response speed for the adaptive equalization filter is set
1
in four levels.
2
The sensitivity is highest with 0 and lowest with 3.
3
0
The detection sensitivity for detection of changes in the relative
1
speed is set in four levels.
2
The sensitivity is highest with 0 and lowest with 3.
3
0
The detection sensitivity for the fault detection function is set in four
1
levels.
2
A fault status is detected when a status where a normal signal can
3
not be detected consecutively for 5 tracks over the following track
values.
0: 1/2
1: 3/4
2: 7/8
3: 15/16
SLOW
The compensation speed in PLL frequency compensation mode is
FAST
set in two levels
0
In the PLL response speed setting, mainly the phase pull-in speed is
|
controlled. The response speed becomes faster with larger values.

0
The strength of the frequency pull-in operation of the PLL phase
1
comparison characteristic expansion function is controlled in four
2
levels. The action is weakest with 0 and strongest with 3.
3
When the data acquisition ratio at the time of special playback is bad,
it can be improved by controlling this parameter.
C13
The setting of the PLL response speed controls mainly the frequency
0
pull-in speed. The response becomes faster with larger values.

0
Setting of the threshold value for judging the signal quality after

equalization
110
The judgment result for the signal quality is used for adaptive
|
equalization, PLL, fault detection function, and other control.
