PRODUCT DETAILS

TECHNICAL FEATURES

The ARC (Automated Remote Control) system enhances the performance of all conventional lighting fixtures: from theatre spots, to TV luminaires and even video projectors.
In practice, these fixtures, although more complex and expensive than the corresponding traditional models, offer a much higher level of performance and, in the medium term, a significant cost saving.
A single motorised spot, be it a Fresnel, PC or others, can in practical use replace two or more conventional spots.
This represents savings, not only with the need for fewer lighting fixtures, but also reduced cable runs, reduced dimming requirements and the all important saving on power consumption.
The use of intelligent motorised spots can also save time.
No longer will it be necessary to spend valuable time and man power flying fixtures in or focusing at high level (usually above awkward stage sets).
All  focusing can be carried out from the control desk and, once a focus position is defined, memorising the movement for future repetition.
Last but not least, intelligent motorised spots provide an important creative aspect for the lighting designers who have available a flexible and powerful tool for applications and results that are unobtainable with conventional fixtures.

High Precision Focusing
The DMX control signal uses 2 channels each of 8 bit, giving a control definition higher than 1/10,000 and, thanks to the precise mechanics, can guarantee a physical focusing precision better than 0,01 degrees.

Smooth and progressive movement
The use of C.C. motors, controlled by an encoder for speed regulation and a potentiometer for accurate positioning, allows a smooth movement, with progressive accelerations and decelerations, even on larger fixtures.

Total noise-free focusing
Thanks to the use of largely over-sized worm gear motors, the spot movement is absolutely noise-free. This allows focusing to be adjusted during the show, without disturbing the audience.

Position maintained – no reset necessary
In the case of power failure, even during the show, all spots will maintain their most recent position and settings. Once power is restored, the fixtures do not require a “reset” to return to the original position. Even if the fixture is powered down for lamp replacement the spot will return to the original position when power is restored.

Possibility of manual positioning
The provision of a clutch system built onto the motors allows for pan, tilt, beam and iris adjustment to be made manually without causing damage, even when the power to the fixture is on. This also acts as a safety feature. For example, if the fixture were to be accidentally hit by a piece of scenery, the motors will move freely, reducing the risk of damage to unit.

Flexibility of use
Over 360° of pan is obtainable so that full horizon can be covered. The degree of tilt is greater than 180° making lighting from the grid, to downlight on the stage and even the audience possible. It is also possible to include in the software a dedicated function in case any lamps utilised do not allow the fixture to be positioned upside down. The spots can be hung on
