Dimmer Fire

Dimmers run coolest at the bottom and top of a channel faders travel and work hardest i.e. heat up the most, at around 60%. If you listen to the dimmer choke buzz, which is audible on most dimmers, you will hear when the heat dissipation peaks. Some dimmers made for rock and roll are designed with the operating needs being constant colour changes and chases. They cannot handle long scene settings that occur in a theatre environment. When choosing a new dimmer, read the users manual carefully as it may mention noisy fans and warn the user not to install the dimmers in an acoustically sensitive environment, i.e. not on the stage or in the wings. You cannot disable these fans as you will then run the risk of a dimmer fire.
