1)
Set the BUS control data to the preset value.
2)
Set SW50 to A (maximum gain), turn the Y mute off (1), and turn the black stretch gain off.
3)
Connect pin 78 to an external power supply (PS), increase the voltage from V53, and plot the resulting change in
voltage S1 of pin 3.
4)
Next, turn the black stretch gain on (0), set the black stretch point 1 to the minimum (000), increase the PS voltage
from V53 as in 3), and plot the resulting change in voltage S2 of pin 3.
5)
Set the black stretch point 1 to the maximum (111), increase the PS voltage from V53 as in 3), and plot the change in
voltage S3 of pin 3.
6)
Use the diagram below to calculate the intersections VBST1 and VBST2 of S1, S2, and S3. Use the following formulas
to calculate PBST1 and PBST2.
PBST1 [(IRE)] = ((VBST1 [V] V49 [V] ÷ 1.4 [V]) × 100 [(IRE)]
PBST2 [(IRE)] = ((VBST2 [V] V49 [V] ÷ 1.4 [V]) × 100 [(IRE)]
