Chapter 4 Adjustments and settings for recording (continued)

4-9 Menu-driven function setup

The functions can be set up using the unit’s menus.

4-9-1 Setting the USER SW GAIN switching

This unit allows three other modes to be used in addition to the L/M/H standard gain settings: the analog gain-up S.GAIN (super gain) mode to achieve a gain of 30 dB or more, the cumulative gain-up DS.GAIN (digital super gain) mode which uses progressive drive, and the LINE MIX GAIN mode where the gain of two lines is mixed.

To select these functions, perform menu operations to open the <USER SW GAIN> screen from the OPERATION page, select the S.GAIN item and DS.GAIN item, and preset the gain to be used for each item. Furthermore, select the LINE MIX function on the <USER SW> screen.

For instance, if the S.GAIN, DS.GAIN and LINE MIX GAIN functions have been allocated to the USER MAIN button, USER1 button or USER2 button, the gain can be increased by using these buttons in combination with the USER buttons.

1)To increase the gain without increasing the perceptible noise

The DS.GAIN function and the LINE MIX GAIN function are used.

2)To increase the normal analog gain (in which case, the amount of noise will increase)

Use only the S.GAIN function.

<Note>

Note that the accuracy of AUTO IRIS, White Balance, and Black Balance may be influenced by an increase in noise.

3)To use the unit in the ultra-high-sensitivity mode

Use the S.GAIN function and DS.GAIN or LINE MIX GAIN function in combination. However, exercise care during operation since image lag will become more conspicuous with moving subjects the more the gain is increased by using the DS.GAIN function.

When shooting moving subjects, keep the gain increase with the LINE MIX GAIN function or DS.GAIN function to under +12 dB.

4-9-2 Selecting the F.AUDIO LEVEL control function

This function enables the recording level to be adjusted using the F.AUDIO LEVEL control.

To select this function, perform menu operations to open the <MIC/AUDIO> screen from the VTR MENU page, and set whether to enable or disable the F.AUDIO LEVEL controls for the system selected as the input signals using the FRONT VR CH1 and FRONT VR CH2 items.
