NSI ND 4600 Operation Manual page 2

Dimmer packs are the heart of any stage lighting system. They translate coded signals
generated by controllers into power levels required to drive high power lamps to desired
intensities.
The NSI ND 4600 and ND 5000 satellite dimmer packs are both fully user addressable
allowing assignment of four of a possible one hundred twenty-eight control channels.
Microplex technology, developed by NSI for the stage lighting market, is the electrical
marriage of microprocessor technology with digitally controlled multiplexing. Microplex
technology allows your system to be connected using standard microphone cables or even
audio snakes. System expansion is further simplified through the ability to daisy chain
additional dimmer packs to an existing system. This application of Microplex technology
makes system set up and operation easy and convenient. In addition, NSI products have been
known to be compatible with other manufacturer's lighting products that use the same
microphone cable interface.
Our philosophy at NSI is to utilize only the highest quality components. Problems that
often plague dimmers such as flickering lights, buzzing in audio equipment and triac failure are
minimized with toroidal devices. In place of triacs, NSI only uses professional grade dual
SCR's.
You can be confident your NSI dimmer packs feature the best performance and
reliability standards available.
