Effects

This section describes the effects provided by the ELP Profile fixture. See 'DMX protocol' on page
25 for a full list of the DMX channels and values required to control the different effects.

Dimming

Overall intensity can be precisely adjusted from 0 to 100% using 16-bit coarse and fine control. In
1Ch or 2Ch mode the control is 8-bit. In 1Ch mode this is the only control.

Strobe effects

An electronic shutter provides instant open and blackout, random and variable speed flash from 1
to 12 flashes per second, and pulse effects.

Manual focus

The ELP profile has a unique "Fine Focus" system which allows you to easily make small focus
adjustments using a gear-based knob on top of the lens tube. To focus the fixture, loosen the
thumbwheel bolts on the top and bottom of the lens tube slightly, then turn the focus knob to slide
the lens in or out of the tube. Tighten the thumbwheel bolts again to hold the focus setting.

Manual beam shaping shutters

The fixture has 4 manually operated beam shaping shutters.

Use of gobos and irises

The fixture will accept a standard A & B-size gobo holder or iris in the gobo/accessory gate. There
is a sliding cover over the gate to prevent light spill and retain the gobo holder in the fixture. To
open the cover, loosen the two thumbscrews at the sides of the cover and slide it towards the lens.
When the gobo holder or accessory is installed, slide the cover back so it holds the gobo in place
and tighten the thumbscrews.

Use of color filters

Using the color filter frame you can add color correction or diffusion filters to the front of the unit.
Push the securing clip to one side to release it. Ensure the securing clip is clicked back into place
to prevent the color filter frame from falling out.
