Creating a gamut
alarm cube The cubes in the Truelight SDI unit are arranged in pairs—the second cube in a pair is often
a gamut alarm version of the first (see
Selecting cubes on page 17). Gamut alarm cubes are
generated from a profile just like other cubes in the SDI unit.
To create a gamut alarm version of a cube:
1
First load the profile for the normal cube into the Truelight application by selecting
Profile > Open > [profile] .
2
Select the View tab.
3
From the Gamut Alarm list, select the type of gamut alarm that you would like to
create. The options are:
• Classic : Shows the colours in the original image that cannot be reproduced on the
display. All other colours are shown as greys.
• Map : Highlights the colours in the original image that cannot be reproduced on the
display. Colours that underflow are marked as red; colours that overflow are marked
as green; colours that underflow in one channel but overflow in another are marked
as blue. All other colours are shown as greys. The
Map option is better than Classic
at showing up problems in blacks and whites.
Make sure that you do not touch any of the other controls.
4
Save the profile ( Profile > Save As... ) and edit the name so that it includes the word
'gamut' or 'alarm' (for example).
5
Click OK .
6
Download the cube to the Truelight SDI unit following the instructions on page 9 .
Testing cubes prior
to download Before committing a cube into one of the slots in the SDI unit, it is possible to preview it.
To do this:
1
Select the Current display option from the top of the Cube Transform list in the
Hardware panel.
2
Click on Load [profile] cube .

This updates the output of the SDI unit directly without overwriting any of the slots.
It is therefore possible to experiment with different profile settings (for example, to
interactively match a test image on the monitor to a reference image) before
committing the cube to the box.
