for Audio Channel 2 assigned.
Pressing the button switches the input signal
in the following order: FRONT

W.L.

REAR. Note that the AUDIO IN switch can
also be used to change the input signal: later

Function of the RET button at the lens assigned.

PRE REC:

PRE RECORDING switch ON/switch OFF
function assigned.

SLOT SEL:

Function of switching the target P2 card

PC MODE:

The function to turn on or off the assigned
USB device or USB host mode. Switching
between the USB device and USB host
modes is set by selecting the PC MODE
SELECT menu option in the SYSTEM
MODE screen on the SYSTEM SETTING
page.

Note

When the remote controller, AJ-RC10G
(option), is connected and I.OVR or C.TEMP
is assigned to the USER button on the side
of the AJ-RC10G, operation of the jog dial
button on the main unit is disabled.

AJ-HPX2000 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 CAM
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 noise:

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

2) To increase the normal analog gain:

(noise is increased)

Use the S.GAIN feature alone.

Note

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

3) To achieve ultra-high sensitivity:

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.

S.GAIN:

An analog gain increase with an asterisk is
one that is valid. One without an asterisk is
