The VDPC174 allows you to program 12 scanners with 16 DMX channels each, 30 banks of 8

programmable scenes, 6 chases of 240 scenes and all this by means of 8 channel sliders, a

the movement of a fixture. To increase your ability to dazzle the audience, this unit allows you to

assign and reverse DMX channels. In addition, two units can set up communication so that they
can send or receive a complete file dump.
