3. Adjust the ColorMerge module to the desired orientation. You can rotate ColorMerge
180 ° to any angle on the Source Four rear housing assembly. This enables you to
stack the fixtures close to each other or fit a fixture into a confined space.
4. Tighten the thumbscrew and Philips set screw to lock the module onto the Source
Four fixture.
Caution: The Source Four fixture with a ColorMerge module installed must be
mounted or suspended so that the electronics housing of the
ColorMerge module is never above the Source Four fixture (see Figure
C-2).
5. Insert the front barrel as-
sembly onto the front locking
ring of the ColorMerge
module, engaging the barrel
assembly into the ColorMerge
locking ring channels.
6. Adjust the front barrel
assembly to the desired
orientation and tighten the
thumbscrew and Philips set
screw to lock the front barrel
assembly to the ColorMerge
module.
7. Mount the unit using safety
cable at the mounting
location.
Optimizing Performance
Soft Edge Beam
For optimum performance from ColorMerge and the Source Four when you need a soft
edge always move the lens tube out (i.e. away from the lamphouse) from the focus point,
not towards.
Beam Adjustment
The fitting of ColorMerge will slightly alter the flat field adjustment of the Source Four.
This is easily corrected using the two concentric adjustment knobs located on the rear of
the Source Four lamp housing. The controls allow you to align the lamp and adjust its
field. The outer knob centers the lamp within the reflector while the inner knob adjusts
the lamp's field.
1. Turn on the Source Four and aim it at a flat surface.
2. Unlock and loosen the outer knob by turning it counterclockwise.
