NSI ND 4600 Operation Manual page 6

AC OUTPUT RECEPTACLES
Dual standard AC outlet receptacles are provided for each channel of both the ND 4600 and
ND 5000. These receptacles provide power to the lamps in your lighting system. The amount of
power supplied to these outlets control the intensity of the lights they drive. Multiplexed signals
received from your NSI controller are translated into power levels to achieve the desired light
intensity. Each dual receptacle corresponds to a single channel with the maximum power
capabilities described in the specifications section of this manual. Under no circumstances
should maximum recommended power capabilities be exceeded. To do so may be hazardous
and will void your warranty. Most incandescent lamps and fixtures may be connected to these
outlets. Do not connect any other electrical appliances or equipment to the dimmer packs.
MICROPLEX INPUTS
Both the male and female Microplex connectors may be used for input signals. Microplex
technology allows your system to be connected using standard microphone cables or even audio
snakes. Microplex may be received from your NSI controller or another dimmer pack. The
Microplex system also provides D.C. phantom power to your control unit eliminating the need
for AC power cords on any NSI controller. Up to one hundred twenty-eight individual control
channels plus phantom power to your controller may be transmitted through a single
microphone cable.
MICROPLEX EXPANSION
The male and female Microplex connectors are wired in parallel allowing either one to be used
for input or output of control signals. When used as an output, the Microplex connectors will
provide control signals to another dimmer pack. This is called daisy chaining and makes
expansion of your system easily.
