Rosco DMX Iris
Having complete control over the beam spread of your leko just got easier. The new Rosco
DMX Iris is quiet, dependable, affordable, and a perfect complement to the I-Cue Intelligent Mirror. This 24 leaf motorized iris unit can be used with your ETC Source Four
, Selecon Pacific or most other modern lekos. Unlike other iris units that have only 18 or fewer leaves in the aperture, the Rosco DMX Iris creates an even edged, perfectly round aperture all the way down to its smallest diameter. Using 1 channel of DMX512, the DMX Iris's movement is smooth even along very slow cross fades. A microprocessor controlled stepper motor connects to the mechanical arm of the iris unit, replacing the unreliable noisy chain drive system found in other products. A manual knob lets you use the DMX Iris without DMX control just by dialing in the aperture size you want, just as you would a conventional iris unit. The Rosco DMX Iris requires a non-dim circuit and is auto-sensing from 100-240 volts for use anywhere in the world. No costly external PSU is needed.In the Box:
- (1) Rosco DMX Iris unit

Insert the DMX Iris into the iris slot of your
luminaire with the motor box extending
towards the front, the lens end, of the
light. It may be necessary to angle the
yoke of the luminaire back to allow access
into the accessory iris slot. Note that on
certain luminaires, the sliding cover of
the iris slot may have to be removed to
allow the DMX Iris to fit properly.Caution: Make sure to route the power cord and DMX cables to avoid the
extremely hot back end of the luminaire. Failing to do so could result in
melting cords, signal failure or fire!
