ration adjustment. 0 = Level max, 63 = Level min.
39 Wide Band: Perform low frequency (fs= 300 Hz) sepa-
ration adjustment. 0 = Level min, 63 = Level max.

NTSC IC 221-1376 FROM 62 TO 111
62 Akb-T: Selection of timing pulse, which generates
reference pulse (Set to NORMAL mode at power on).
Range 0-1, 0 = NORMAL mode (reference pulse gener-
ated by SCP input only), 1 = V compression mode (ref-
erence pulse generated from VTIM-IN,HP-IN).
