Focusing the Beam

Figure-1.4 Focusing the beam.

Step 1: Loosen the beam focus knob located under the barrel as shown in Figure-1.4.

Step 2: Slide the lens tube forward or backward to achieve the desired beam edge.

Step 3: Once the fixture is focused, tighten the beam focus knob.

Shaping the Beam

The beam can be shaped using the shutters (see Figure-1.1), a pattern, an optional drop-in iris, or

by rotating the barrel.

Pattern Projection

The pattern holder slot is on the top side of the barrel and in front of the shutters. It accommodates

A-size, B-size, and glass pattern holders.

Figure-1.5 Pattern holders.

Note:

Pattern projections generally look best when used with the included Soft Focus

diffuser.

Note:

Because the Source Four aperture is 3 inches wide, ETC recommends using A-size

patterns for maximum pattern effectiveness.
