Technicolor - Thomson LDK 23hs VTR switch, Vertical Shift switch V-Shift, Clean Scan button CLS

1VTR switch

The VTR switch is disabled in this mode. In triax mode however, it will switch the microphone of the headset to the production intercom channel.

2Vertical Shift switch (V-Shift)

The V-Shift switch is disabled in this mode.

3Clean Scan button (CLS)

The camera does not have a ‘clean scan’ facility. Although it is possible to select a variable exposure time between 151/181 to 829 Hz, it is not possible to increase it above the nominal setting (1/150 of 1/180).

Therefore, it is not possible to eliminate the horizontal bars when shooting monitors with this camera because their refresh rates are below 150Hz.

4Auto White Balance button (AWB)

The AWB button is a momentary switch, used to start the automatic white balance process. The camera, when pointed at a white area in the centre of the picture, measures and stores a colour temperature setting in the AW1 or AW2 memory position.

The AWB button only operates if the colour temperature switch is in the AW1 or AW2 position. Refer to Section 5 for more information on how to use the AWB.

5Colour Bars button (Bars)

The Bars button is used to switch the colour bar test signal on and off. (The lens iris closes automatically when the colour bars are switched on.)

6Colour Temperature switch (Col. temp)

This up/down scroll switch allows a choice between three preset colour temperatures:

•3200K (3.2K) - for studio lighting conditions

•5600K (5.6K) - for outdoors, clouded conditions

•7200K (7.2K) - for outdoors, clear blue skies and two memory settings AW1 and AW2. These two memory settings can be filled with measured values using the AWB button (4).

7Gain switch

This up/down scroll switch gives a choice between four gain settings that, except for the 0dB setting, can be set in the install menu (refer to section 6).

8Filter switch

1 : Clear

2: ND 0.6 filter

3: ND 1.2 filter

4: ND 1.8 filter

5: 4 Point Star filter

6: 6 Point Star filter

7: Cap (lens closed)
