Description
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.
