Gain
A nominal video signal level is usually 1 volt peak-to-peak for composite video, 0.7 volts for
component or RGB video, or 0.3 volts for the chrominance subsection, at which level a fully
saturated picture is transmitted to the acceptor. However, for cases where the video signal is
attenuated, a low-noise, high-gain analog amplifier is built into quality video processing equipment.
This amplifier provides video gain control whereby the video signal can be boosted or reduced. Dark
pictures resulting from low level lighting are easily adjusted.
The
Gain
drop-down menu enables controlling the video gain from
Off
or in steps from 1 to 9.
Click

when you finish setting the gain.
