X-ND100 (Digital Noise Detector) is used to detect ambient noise, automatically calculate the noise
SPL, and transmit the SPL data to X-DCS3000. It is an important component to fulfill the function of
automatic volume control. While broadcasting, the sound is mixed with ambient noise. In order to
measure the noise SPL accurately, X-ND100 measures broadcast signal from speaker lines, compar-
ing with the one from microphone to get the actual noise data.
Connect to X-DCS3000 by a pair of cables, through which fulfill
communication and power supply.
Max. 5 noise detectors for each channel.
Currently collect broadcast signal and noise signal.
Max. transmission distance is 1000m.
Flush-mounting in ceiling.
Fire-proof ABS shell.
Ideal for indoor installation.

1. Installation
Builders can conveniently install the noise
detector into a hole with diameter of 160mm in
the ceiling, and fix it with the spring clamps on
both sides of shell. Thickness of ceiling is
5~25mm.
2. Wiring
There are two terminals inside the noise detec-
tor. One is used to connect the control
line for communication and power supply, and
another is used to connect speaker line. The
polarity of wires shall conform to the marks
beside the terminals. Generally, 0.75mm2
twisted wires are recommended. If the distance
from noise detector to controller is up to 1000m,
please use 1mm2 twisted wires.
