6. page vi Version 1 1 SmartRack User Manual SmartRack User Manual ARRI GB Ltd e e Digital Dimming Explained There are good reasons why users of professional dimming equipment are now only willing to accept true digital dimming equipment such as ARRI SmartRack and SmartPack They are Accuracy digital dimmers are able to regulate output levels to reproduce precisely recorded intensities even when mains power is fluctuating Reliability with fewer electronic components digital dimmers literally have less things to go wrong Smarts with processing power on board digital dimmers can perform tasks previ ously impossible with analogue techniques These include diagnostic functions indi vidual dimmer profile and response speed settings and more Cost a well designed digital dimmer typically uses fewer electronic components and is therefore cheaper to manufacture The key to the accuracy of digital dimmers is regulation This means that the dimmer is constantly measuring the rms voltage of each supply phase a total of 12 800 times per second in the case of ARRI SmartRack to build up an accurate picture of the condition of the mains supply to each dimmer Using this information the power devices are pre cisely controlled to compensate for any mains voltage fluctuations and produce a con stant voltage output for any given control level Of course in an age where virtually all lighting control co
