Double core shielded cable
Maximum distance up to1000m
Measure broadcast signal and noise signal real time
X-ND100 is an optional accessory for X-618 system. It is used to detect ambient noise, calculate noise sound pressure level, then send data to X-DCS3000. X-DCS3000 will conduct automatic volume control in assigned area, change current sound pressure level of broadcast to improve broadcast clarity.
Main characteristics:
• Connect to DCS by a pair of cables which transmit data and power supply
• Max. 5 noise detectors for each channel
• Real time to measure broadcast signal and noise signal
• The maximum distance is up to1000m
• Flush-mounting in ceiling
• Fire-proof ABS shell
• Ideal for indoor installation
