With the Manual Control Box (MCB), either the frame rate or the shutter angle can be manually adjusted. In
combination with the Speed Control Box (SCB), manual speed/shutter, speed/iris and shutter/iris ramps can
be performed – see the Combined use of the Speed & Manual Control Boxes section of this Quick Guide.
When the Speed and Manual Control Boxes are used together, the ramp time can be manually controlled.
Note: The MCB has to be removed prior to mounting or removing the SCB or Studio Camera Handle on the Studio.
Mounting
• On the Studio, remove the MCB port cover prior to mounting the MCB with two 3 mm hex screws.
• On both the Studio and the Lite a cable connection with the MCB is possible: Fix the MCB to either the MCB
Cable Adapter or the Remote Control Station with a 3 mm metric hex wrench. Both components can be linked
to the camera’s CAC connector with a cable: Either KC 65-S (3m/9ft) or KC 69-S (15m/45ft). These can be
extended a further 50m/165ft by using the Cable Drum.
Note: The MCB Cable Adapter can either be used with the MCB or the Timing Shift Box (TSB).
Note: When a Studio magazine is in back load position, it has to be removed for mounting or removing the MCB.
Compatibility
The MCB and the TSB can be used simultaneously to combine a ramp with a streaking effect. To do this, the
use of the MCB Cable Adapter, the Remote Control Station or the CAC Distribution Box is necessary.
Adjusting the frame rate
The FPS 1 position of the handwheel is the minimum (1 fps), the FPS 2 position is the maximum frame rate
(Studio: forward 60 fps, Lite: forward 40 fps, both: reverse 32 fps).
• Set the MANUAL CONTROL switch to FPS.
• Turn the handwheel to adjust the frame rate.
If the SCB is connected and its SPEED CONTROL switch is ON, the preset frame rates FPS 1 and FPS 2 of the
SCB determine the minimum and maximum fps of the MCB.
Note: The MCB speed setting has priority over the speed setting of both the Camera Control Panel and the SCB.
Adjusting the shutter opening
The handwheel MIN
position is the minimum shutter opening (about 0°), the MAX position is the maximum
shutter opening (180°).
• Set the MANUAL CONTROL switch to
.
• Turn the handwheel to adjust the shutter angle.
Note: If the SCB is connected to the camera, make sure its COMPENSATION switch is set to OFF.
Note: We don’t recommended shooting at shutter angles below 11.2° because correct exposure cannot be guaranteed.
Note: If a shutter/iris (depth of field/motion blur) ramp is set in combination with the SCB, the shutter opening
range of the MCB handwheel is restricted to MIN 11.2° and MAX 180°.
