INTRODUCTION

Dimmer and relay packs are the heart of any stage lightingsystem.

They translate coded signals generated by controllers into power levels
required to drive high power lamps to desired intensities.

The NSI NR 3000 satelliterelay pack is fully user programmable

allowing assignment of four of a possible sixty-four control channels.
Micro-plex. a new technology developed by NSI for the stage lighting
market. is the electrical marriage of micro-processor technology with
digitally controlled multiplexing. This technology allows all NSI lighting
components to be connected with standard 3-pin microphone cables or even
audio snakes. System expansion is further simplified through the ability
to daisy chain additional relay packs to an existing system. This

application of Micro-plex technology makes system set up and operation easy
and convenient.

Our philosophy at NSI is to utilize only the highest quality

components. Problems that often plague relays such as flickering lights,

buzzing in audio equipment and triac failure are eliminated in NSI

products. In place of unreliable triacs, NSI only uses professional grade

dual SCR's.

You can be confident your NSI relay packs feature the best performance

and reliability standards available.
