The Crystal Pulse is one of the most exciting projected lighting effects ever created. Crystaline images which constantly change colour, through the spectrum, in instant response to sound. The Crystal Pulse is designed for use with the Solar 100C and Solar 250 Effects Projectors and is activated by the inbuilt microphone or may be connected directly via a jack socket. Quite simply the Crystal Pulse is a fantastic effect which anyone will interact with and respond to.
