Features of the camera unit

Wide-ranging video gain selection

A value ranging from –6 dB to +30 dB can be selected for the gain using the setting menu and GAIN switch. Even when the gain is increased for shooting in dark locations, images with minimal noise can be obtained because of the high signal-to-noise ratio. The super gain function can be allocated to the USER button, and 30 dB can be selected using this button.

Automatic adjustment of black balance and white balance, and memory function

The black balance and white balance can be adjusted automatically by means of some simple switch operations.

The adjustment settings remain stored in the memory even after the power has been turned off so that the need for the balance to be re-adjusted each time the power is turned on is obviated.

Two memories, A and B, are used to store the white balance, and it is possible to retain two adjustment settings per color temperature conversion filter, making for a total of 8 settings altogether.

When the color temperature conversion filter is rotated, it is automatically adjusted to the white balance. (Using menu settings, this can be set for two filters only rather than for each and every filter.) When the unit is shipped, 3200 K is stored as the preset value for the white balance. This value can always be recalled when no time is available to perform adjustments.

(The preset value can be switched between 3200 K and 4300 K.)

Character display function

The unit comes with functions for showing the switch settings, automatic black balance and white balance adjustment statuses, warning displays, etc. on the viewfinder screen.

Moreover, when a battery in the Digital Magnum Series made by Anton/Bauer Corporation is used as the unit’s power supply, the remaining battery charge can be displayed as a numerical value on the viewfinder screen.

Warning system for indicating VTR unit statuses The user is alerted to problems in the VTR, tape-end, battery consumption, etc. by various alarm lamps and alarm tones. The remaining tape time can also be checked by a character display inside the viewfinder.

4-piece filter disc sets available as standard accessories

The filter best suited to the subject’s brightness and color temperature can be selected. Two independent sets of filter discs, one for CC and one for ND, each with four filter discs, are provided as standard accessories.

Automatic aperture reference value finely adjusted The reference value used for the automatic aperture adjustment can be finely adjusted by performing setting menu operations.

Generation of color bar signals and reference audio signals

The unit contains a circuit for generating color bar signals so that a color monitor can easily be adjusted. It also incorporates a circuit for generating reference level audio signals to enable the audio level to be adjusted with ease.
