138 Hog 4 Operations Manual
Swap Axes
Depending on a fixture's orientation in the rig, you may want to swap its pan and tilt axes. For
example, if units are rigged facing across the stage rather than facing up or down stage, then
swapping the axes keeps the Trackball movement and the fixture movement the same. This
also ensures that fixtures selected in groups all move in the same direction as the Trackball
is moved.
Fixtures that are rigged in other positions, for example on the stage floor as opposed to
hanging, then combinations of swap axes and pan invert and/or tilt invert may be required.
To swap axes:
1. Open + Fixtu re
2. Scroll to the desired fixture, and select its SwpAxe s cell.
3. Press Set, and choose Swap to swap axes.
Pan Invert / Tilt Invert
Depending on a fixture's orientation in the rig, you may want to invert its pan and / or tilt
moment. For example, if units are rigged on the stage floor as opposed to hanging, then a pan
and / or tilt invert may be required.
To invert pan and / or tilt:
1. Open + Fixtu re
2. Scroll to the desired fixture, and select either its Pa n Invert or Tilt Invert cell.
3. Press Set, and choose Yes to invert the axis.
Intensity % (proportional patch)
You can use intensity percentage (also know as proportional patching) to change the intensity
value output by the console to a fixture, relative to the intensity value that has been
programmed. All intensity values for the fixture are reduced in proportion, so that with a
proportional patch of 80%, a programmed intensity of 100% would be output as an intensity of
80%, and one of 50% would be output as 40%. You can use this to limit the maximum
intensity of a fixture so that it never goes above 80%, for example, by assigning the
proportional patch to 80%. Please note that reductions to the output of a fixture caused by
changes to the intensity % value are not reflected in the values shown in the output window.
This is because reductions to the fixtures intensity output are calculated in DMX only and
therefore can only be viewed in the DMX output window.
To assign a fixture's intensity % (proportional patch):
1. Open + Fixtu re
2. Select the In tensity % cell for the fixture required.
3. Set, [ p e r c e n t a g e ] , Ente r : enter a percentage.
4. To return the proportional patch to normal, assign the value to 100%.
You can assign a proportional patch value of above 100%. For example, if you patch at 200%,
the intensity value that the console outputs will be twice that programmed. A programmed
value of 25% will give 50% output, and 50% will give 100%. Programmed levels above 50%
will not, regrettably, give fixture intensities above 100%.
Note that if you proportionally patch a fixture, its intensity will still be displayed on the
console in the range 0 to 100%, even though the output value will be varying over the range
defined by the proportional patch value.
