Step 9 — Power on
Connect power to the DA and to all input and output devices.
Step 10 — Adjust potentiometers for output cable lengths (if needed)
•If using very short output cables, ensure that the potentiometers are in the unity gain position; that is, with the arrow on each potentiometer pointing to the dot beside or above it. If the potentiometers are already in the unity position (shown in the example for inputs 1 and 2, at right). Do not change them.
If the potentiometers are not in unity gain position, rotate them, using a small screwdriver.

•If using long cables, follow these steps to adjust the potentiometers:
a.Send the Color Bars test signal to the input, using a video test generator such as the Extron VTG 300.
b.Adjust the Gain potentiometers for output pair 1 and 2 until the signal level at the far end is the same as the input (or the display shows the correct brightness and contrast).
c. Adjust the EQ potentiometer |
for outputs 1 and 2 so that no |
overshoot or round front corners |
appear at the far end on the scope |

(or until you see a sharp picture |
with no smearing). |
d. Repeat steps b and c for the rest of |
the outputs. |
