Gain
Manual Gain Control
You can manually adjust the gain of the 3 preset gain levels (L: low, M: middle, H: high). Each level can be set
independently. You can also fine-tune the gain in 0.5 dB increments.
Assigning Gain Values
You can assign separate gain values to the L, M and H preset levels.
Then, you can activate the desired gain level using the GAIN button.

sequence: AGC

NOTES
• When you select high gain levels, the picture may flicker slightly. The 33.0 dB gain level in particular, allows you
to shoot video with a higher sensitivity but is more prone to the appearance of noise and artifacts (white dots,
vertical streaks or blocking).

transition when changing the gain.
