Setting Gain

This function electrically boosts the light sensitivity when there is insufficient illumination on the object. You can set the gain of the video amplifier according to the brightness of the object. Select the setting mode according to your shooting conditions.

[GAIN] Selection

Switch

[FULL AUTO] Switch

Manual Iris (Manual Adjustment) Mode

Set the [IRIS] switch on the lens to AMB to enter Manual Iris Mode.

Turn the iris ring on the lens to adjust the iris manually.

Memo :

●Even during Manual Iris Mode, the camera recorder enters forced Auto Iris Mode while the [IRIS AUTO] button is pressed.

Auto Iris (Automatic Adjustment) Mode

Set the [IRIS] switch on the lens to AAB to enter Auto Iris Mode. The iris is automatically adjusted according to the brightness of the object.

Or, set the [FULL AUTO] switch on the camera recorder to AONB to enter Auto Iris Mode. The iris is automatically adjusted according to the brightness of the object.

Memo :

●When [Iris Control] in the [Camera Function...]B[FULL AUTO...] menu is set to AOffB, you can adjust the iris manually even if the [FULL AUTO] switch on the camera recorder is set to AONB. (A Page 75)

●You can use the cross-shaped button (H, I) on this camera recorder to set the target level (brighter/darker) of the auto iris. You can also use the menu to set the tracking sensitivity of the auto iris. (A Page 73)

Fixed Gain Mode (Manual Gain Switching)

You can select the gain of the video amplifier using the [GAIN] switch on the camera recorder.

The default positions of the switch are as follows.

[L]: 0 dB (No electrical boosting.)

[M]: 9 dB (Boosts sensitivity by about 2.8 times.)

[H]: 18 dB (Boosts sensitivity by about 8 times.)

Memo :

●The gain value of each position can be set to AALCB and within the range of A0dBB to A18dBB (in increments of 3 dB) in the menu. Increasing the sensitivity causes the screen to appear grainier. (A Page 74)

Automatic Gain Mode (Automatic Gain Adjustment)

Set the [FULL AUTO] switch on the camera recorder to AONB to enter Automatic gain Level Control (AALCB fixed). The gain of the video amplifier is automatically set according to the brightness of the object.

In this case, the [GAIN] switch on the camera recorder is disabled.

Memo :

●When [Gain] in the [Camera Function...]B[FULL AUTO...] menu is set to ASW SetB, you can switch the gain with the [GAIN] switch even if the [FULL AUTO] switch on the camera recorder is set to AONB. (A Page 75)
