Setting Lamp Attributes

Absolute and Relative Control Modes

When setting or modifying Lamp settings via the six Control Wheels you

can use one of two modes. The mode is chosen by pressing the rel button:

 Absolute Mode (button LED is OFF)

Whatever value is selected on the Control Wheel(s) is

applied directly to all selected Lamps. Generally you will

use this mode to ensure that all Lamps are exactly the

same, e.g. they have the same Colour or Beam.

 Relative Mode (button LED is ON)

Whatever value is selected on the Control Wheel(s) is

added or subtracted to all selected Lamps. Generally you

will use this mode to ensure that all Lamps are set the

same relative to each other, e.g. they maintain the same

relative Position or Intensity.

The effect of both modes is demonstrated in Fig 8 using the Position

setting as an example.

In this example, two Lamps are pointing a single spot centre stage: if the

Lamps are moved to down stage left in Relative mode, the beams will

follow each other (provided that Auto tracking has been correctly set- up).

If the same two lamps are moved in Absolute mode, the beams of both

Lamps will adopt the same angular position setting.
