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 tofulfill 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, comparing with the signal from

microphone to get the actual noise data.
