1)
Set the BUS control data to the preset value.
2)
Turn the Y mute off (1), turn the black stretch gain off (1), and connect pin 8 to an external power supply.
3)
With the D.ABL detect voltage at the minimum (000), plot the voltage characteristics of pin 3 in relation to the voltage
of pin 8 when D.ABL sensitivity is at the minimum (000) and the maximum (111).
4)
From the diagram, calculate the SDAMIN and SDAMAX gradients.
SDAMIN, SDAMAX = Y/X

1)
Set the BUS control data to the preset value.
2)
Turn the Y mute off (1), turn the black stretch gain off (1), and observe pin 3.
3)
Turn the black level compensation on (1), measure
V1 [mV], and calculate the following formula.
BLC = (V1/1.4 × 10
