Playback signal envelope level read-out value averaged for each
track of each head
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.
• 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.

The detection sensitivity for the fault detection function is set in four
levels.
A fault status is detected when a status where a normal signal can
not be detected consecutively for 5 tracks over the following track
values.
0: 1/2
1: 3/4

In the PLL response speed setting, mainly the phase pull-in speed is
controlled. The response speed becomes faster with larger values.

The strength of the frequency pull-in operation of the PLL phase
comparison characteristic expansion function is controlled in four
levels. The action is weakest with 0 and strongest with 3.
When the data acquisition ratio at the time of special playback is bad,
it can be improved by controlling this parameter.
