Ultra-high resolution dimming with sunDial quad

sunDial quad, the PLASA Gold award-winning mains LED dimmer from Artistic Licence, has won praise for its ability to provide exceptionally smooth LED dimming with DMX512. Following a firmware upgrade, the product just got even better, with a huge improvement in dimming resolution now achievable with many theatrical controllers.

The latest firmware is available free-of-charge and can be uploaded using DMX-Workshop.

DMX512 can control up to 512 channels and has an 8-bit native resolution. This means each channel can be set to a level between 0 and 255 and is encoded as an 8-bit number (256 levels). sunDial quad has a much higher native dimming resolution of 14-bit, so in normal operation a dimmer curve translation is used - in effect, sunDial picks 'sweet spots' on the response curve to achieve a nice fade.

However, some professional lighting consoles allow two DMX512 channels to be combined to provide up to 16-bit resolution (65,536 different levels). In this scenario, no curve translation is necessary. Following sunDial's latest firmware upgrade, the console can access all the subtle levels available in sunDial's high native dimming resolution, thus ensuring ultimate dimming performance for applications that demand the most subtle effects.

sunDial quad is often used for house lights in theatre, and can be easily integrated with the stage lighting consoles. As many of the favourite theatrical controllers feature 16-bit channel resolution, sunDial quad represents an ideal dimming partner.

sunDial quad also has the major advantage that its firmware can be upgraded (at zero cost) in the field. Customers can achieve this using the Artistic Licence DMX-Workshop free software package.
