Overview
The DMX-IRIS is a DMX-controlled 18-leaf iris for S4 ellipsoidal spotlights, giving the lighting designer remote aperture control from the console. It combines a stainless steel iris, DMX-512 motorization, manual knob operation, and a locking frame that holds position even when the fixture is mounted upside down, sideways, or on an automated yoke.
Why It Matters
Manual irises are useful until the fixture is at trim height and the designer wants the beam to tighten during a cue. Motorized control turns that static accessory into a live creative tool, especially for reveals, specials, cue transitions, and beam-size changes that need to happen in time.
Key Features
- 18-leaf stainless steel iris creates a smooth aperture for tightening or opening the Source Four beam.
- DMX-512 motorized control lets the aperture move from the lighting console during programmed cues.
- Manual knob operation remains available when DMX power or control is not being used.
- Zero switch selects fully closed or fully open as the default aperture position for predictable startup behavior.
- 5-pin XLR in and out, DIP switch addressing, self-check button, and power/signal LEDs keep setup and diagnostics visible on the unit.
Applications
Built for theatre specials, broadcast profile spots, automated Source Four positions, reveal cues, architectural accents, and any rig where an ETC Source Four beam needs remote aperture control.
Compatibility
Designed as a drop-in motorized iris for S4 ellipsoidal spotlights, with AC 100-240 V IEC universal power input and DMX-512 control.
