4-9 Menu-driven Function Setup
Each function is set up using the menu system.
4-9-1 Setting the Switchover of USER SW
GAIN
In addition to the standard L/M/H gain mode, the AJ-SPX900E
supports S.GAIN (super gain) mode, featuring greater than 30-
dB analog gain-up, together with DS.GAIN (digital super gain)
mode, storage-type gain-up based on progressive drive
technology.
To make use of this feature, you need to specify desired gains
through the menu options S.GAIN and DS.GAIN.
For example, if the S.GAIN and DS.GAIN features are assigned
to either the USER MAIN, USER1 or USER2 buttons, three
different gain-up modes are available through button-mode
combinations.
The menu options can be found in the <USER SW GAIN>
screen, which is accessible from the CAM OPERATION page.
1) To increase the gain without increasing noise:
Combine the L/M/H gain and DS.GAIN features.
2) To increase the normal analog gain:
(noise is increased)
Use the S.GAIN feature alone.
3) To achieve ultra-high sensitivity:
Combine the S.GAIN and DS.GAIN features.(Gain
increased by up to 68 dB.)
However, you should be extra careful when using this
combination. With moving subjects, the greater the increase
in DS.GAIN the more annoying the after-images will be.
In this case, limit the increase to +12dB (1/12).
Note that the DS.GAIN feature is disabled when the AJ-
SPX900E is in progressive mode.

4-9-2 Selecting Video Output Signals
You need to select the signals to be output from the VIDEO OUT
and MON OUT connectors.
When the extension board AJ-YA902AG (optional accessory) is
attached, an SDI signal can be output from the VIDEO OUT
connector.
For more information, see [8-2-4 OUTPUT SEL].
4-9-3 Selecting Function for the FRONT
AUDIO LEVEL Control
The FRONT AUDIO LEVEL control can be assigned the function
of adjusting the recording level.
To specify whether or not the FRONT AUDIO LEVEL control is
effective on the channels set to accept input signals, use the
menu options FRONT VR CH1 and FRONT VR CH2. These
options can be found in the <MIC/AUDIO1> screen, which is
accessible from the MAIN OPERATION page.
For more information, see [8-6-4 MIC/AUDIO1].
