Automatic adjustment and memory functions for black balance/white balance
The black set, black balance and white balance can be automatically adjusted by simple switch
operations. Adjustment values are held in the memory even if the power for the unit is turned off,
so there is no need to readjust the balance each time the power is turned on.
There are two memory systems for white balance which can hold four adjustment values each for
the CC and ND filters, making a total of eight adjustment values. When adjustment values match-
ing the illumination conditions are selected from among the values stored in the memory, the unit
is automatically adjusted to the corresponding white balance. (A menu setting also allows adjust-
ment of only two values instead of the values for each filter.) In addition, when the unit is shipped
from the factory, the white balance value for 3200K is stored in the memory as a preset value. This
value can be called when there is no time to adjust the white balance, etc.
Character display function
The unit is equipped with a function that displays switch settings, the automatic adjustment status
for black balance and white balance, warning displays, etc. on the viewfinder screen.
In addition, when using an Anton Bauer Digital Magnum series battery as the unit’s power supply,
the remaining battery level can be displayed numerically on the viewfinder screen.
Warning system for displaying the VTR section status
The unit informs of VTR trouble, the end of the tape, battery wear, etc. with various warning lamps
and a warning tone. The remaining tape time can also be checked by the character display inside
the viewfinder.
Four filter disks as standard equipment
CC (color temperature conversion) and ND (neutral density) filters are provided as standard
equipment. This allows the optional filter setting to be selected from among four combinations in
accordance with the brightness of the subject.
Fine adjustment of the automatic iris reference value
The reference value for automatic iris adjustment can be finely adjusted by setting menu opera-
tions.
Auto close function
The unit is equipped with an auto close function which automatically closes the lens in the follow-
ing cases.
Á
When the black balance is automatically adjusted.
Á
When the power is turned off in the auto iris mode.
Generation of SMPTE/SNG color bar and reference audio signals
The camera section contains a circuit which generates an SMPTE type color bar signal to facili-
tate color monitor adjustments, and a circuit which generates a reference level audio signal to
facilitate audio level adjustments.
The unit also contains a circuit for generating SNG color bar signals which come in handy for
sending signals to communication satellites.
