DimmerThe strongest links in the chain of lights represent the dimmer and Schwitchpacks. Dimmer packs set to analog or digital control signals for controlling the brightness of a lighting device in power. The switch pack (switch = switch) allows the control of consumers which constantly need full voltage, such as motors, strobes, wind machines, etc..Some time ago there was a decisive shift from analog 0-10v technic to digital technic in the light controller world. The biggest advantage of digital control is the better mode of transmission. In addition, the elimination of the expensive, heavy and susceptible control multi-core, since a 2-core shielded cable handles the data transfer. So no errors occur, please use only cables suitable for DMX data!
