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.
