Colour Wheel Options Colour Wheels are available for all projectors and are made from dichroic glass filters which will not degrade throughout life.

Due to lamp colour temperature, only orange, magenta and light blue are available as additional colours for CRE601

Colour Control and Effects

Colour Wheel Speed
The standard fitment is 2.5rpm. A 1rpm motor is available for CRE6155 and some other models. Consult the Crescent technical office for details.

Colour Synchronisation
This ensures that on multi-projector installations, all colour wheels rotate together ie. all projectors have the same colour at the same time or stepped deliberately out of synchronisation.

There are two main applications:

If lateral fibre (BPAK) is being used with a projector at each end (not in a loop), the colour should be synchronised so that the whole length of the fibre cable looks the same.
The other application is with end lit cable (FSPTe) where all the tails need to be the same colour.
Colour synchronisation is available on all projectors which have a colour wheel option. Specify ‘/synchro’ as a suffix to the projector catalogue number, ie, CRE6155/synchro.

Colour Control
Both Analogue (0-10v) and DMX512 (channels 0-255) control systems can be installed. These systems allow preset or variable colour sequences to be programmed from a suitable lighting controller on site. Colour synchronisation is achieved as part of the control process.

Dimming - Neutral Density Wheel
A four step neutral density wheel which can be fitted as an addition (or replacement) to the colour wheel. This offers 100, 75, 50 and 25% light output as the wheel rotates. The wheel can be stopped, synchronised and controlled in the same way as a colour wheel.

Dimming - Mechanical Wheel
Used in conjunction with an analogue or DMX control system, this wheel can provide 0-100% light output. It can be used together with a colour wheel in the CRE6155 and some other projectors. Consult the Crescent technical office for details.

Sparkle Effect
Sparkle Wheel - Fitting either the 2.5rpm or 1rpm motor, this gives a gently flickering effect and is usually used for star ceilings and other decorative applications. This can be combined with colour on the same, or a second motor.

Ventilation
All projectors have fan assisted thermal control, which relies on an open mounting location. For cases where this is not possible, specify CRE2318 Ventilation Kit. Comprising a fan, two louvred finger guards, metal brackets, connecting cable, earth cable, fixing screw kit, cutter template and full fitting instructions. This allows the projector to be mounted in a small or restricted location. If in doubt, contact the Crescent technical office.
