DNW-A75/A75P
A32 : DM VR 1
This menu is used to adjust the frequency characteristics of
a primary cosine equalizer (on the DM-89 board).
There are adjustment data for metal and oxide tapes.
Each adjustment data is provided proportionally to the
number of heads (Y-A, Y-B, C-A, and C-B).
A33 : DM VR 2
This menu is used to adjust the frequency characteris-
tics of a secondary cosine equalizer (main)(on the DM-
89 board).
There are adjustment data for metal and oxide tapes.
Each adjustment data is provided proportionally to the
number of heads (Y-A, Y-B, C-A, and C-B).
A34 : DM VR 3
This menu is used to adjust the frequency characteristics of
a secondary cosine equalizer (sub)(on the DM-89 board).
There are adjustment data for metal and oxide tapes. Each
adjustment data is provided proportionally to the number
of heads (Y-A, Y-B, C-A, and C-B).
A35 : DM VR 4
This menu is used to adjust the guard band width and to set
the DC offset level of an over-modulation compensation
circuit (on the DM-89 board).
There are adjustment data for metal and oxide tapes. Each
adjustment data is provided proportionally to the number
of video channels (Y and C).
A36 : DM VR 5
This menu is used to adjust each dropout threshold level of Y
and C channels and to set the RF envelope threshold level.
There are adjustment data for metal and oxide tapes
provided for each dropout threshold level.
There are adjustment data for high (H) and low (L) limits
provided for the RF envelope threshold level.
A37 : TBC VR
This menu is used to set each read clock timing of Y and C
channels and to set the data of a PB VISC phase detection
circuit (on the TBC-23A board).
