Pulsars new Matrix Controller and Matrix Dimmer Pack

From Lighting & Sound International, December 1985

Pulsars new Matrix system comprises a Matrix Controller and remote Matrix Dimmer Pack. The equipment can be used for a number of combinations, giving some fantastic effects for dance floors, wall and ceiling and other two-dimensional displays, say the company.

The Dimmer Pack controls up to 5 amps per channel of any type of load. The unit controls output on 4 live channels adn 4 neutral channels. Normally the unit would be connected to a Modulator IV and a Matrix Controller. The Modulator delivers four channels of control to the dimmer pack, while the Matrix Controller directs the output of the dimmer pack either to channels 1-4 or 5-8. Thus the unit delivers voltage either to the X-axis of a display or to the Y-axis. In addition the Matrix Controller can direct outputs to a combination of X and Y, creating a Z axis which enables block patterns to move diagonally across hte display. A further subtle effect is created by the partially-lit lamps on parts of the display which are only addressed on one axis.
