GAIN/AGC

AGC Mode

There are three AGC (Automatic Gain Control) modes: auto, on, and off.
In the auto mode, the Spectra II™ and Spectra Lite™ domes automatically adjust the gain–
the amount of amplification the camera places on its video information in order to obtain a
full 1-volt peak-to-peak video signal out. If the iris is manually opened to its wide-open
position and the picture is weak, the AGC can be turned off and the gain increased
manually to improve the picture. For instructions on how to do this, refer to the

Auto Iris

section. When you close the iris, the AGC will turn back on automatically when the lens iris
starts closing.
In the on mode the AGC is on all the time.
In the off mode the AGC is off.
To change the AGC mode:
1. Program preset 95 (28 if in 32-preset mode; refer to the

Preset Functions

section) to
access the main menu (refer to the

Main Menu Access

section). The main menu will
