Great add on controller from LiteLab. This is the perfect advantage controller. This is a ‘Add On’ piece for LiteLab chaser systems. It connects directly into the LiteLab driver pack or if a matrix chase system is being used it connects into the logic controller. Connection is through a flat ribbon style connector and cable. This unit simply adds dim control of the 8 output channels individually. With the standard LiteLab controllers there is usually only a master dim for all channels. This adds more flexibility to the system. Great controller made in the USA.
