The important argument for any dimmer and any customer will be the rise time with the thyristor technology. It provides an idea of how fast the “jump” from zero to the actual voltage will be. This voltage jump can cause “lamp noise” – better filters will reduce that noise. The rise time for TV and theatre applications should be at least 280μs. The MA solution gives you the same rise time across different MA Digital Dimmer modules, so various combinations of different MA Digital Dimmer modules can be used together. Please refer to the tables above for more information about the rise times. Just as important as the build quality is the quality of the filters. The better the filters, the more quiet the entire dimmer. It is especially important to avoid a permanent whir caused by interacting filter elements. MA Lighting has set many quality standards and proven in multiple dimMA installations, how silent thyristor dimmers can work. What's the best dimming solution? The best dimming solution will be the one that fits the customer's requirements as well as his technical needs. In most cases the thyristor technology will be more than sufficient. The best result for any stan- dard dimming system will be the thyristor technology because of its field tested reliability. On the following pages all the dimming solutions MA can offer will be given. All dimming products can be combined becauseof the dimmers for permanent installations and those for tour- ing application work in the same range of rise time. All dimmers have the same high quality filtering and a user friendly interface, starting at the touring dimmers with a built-in display and ending at the dimMA System with its unique configuration and feedback functionality right on the screens of the grandMA consoles.
