Description
The digital noise sensing microphones provide the ability to continually track and monitor the surrounding ambient noise levels. This information is then used to automatically adjust paging announcements to ensure that they are broadcast at a predefined level above the ambient noise. This ensures announcements can be clearly understood over and above the environmental noise at any point in time. They are ideal for use in areas were the ambient noise levels are continually changing such as shopping malls, sporting venues, rail and bus stations etc. and its important to track the ambient noise levels to ensure clear and intelligible announcements.
The DNM’s are available in 2 options as follows: DNM-485 (Provides an RS-485 connection) and DNM-ENET (Provides an Ethernet connection including POE). Both options are fitted with a built-in omni-directional, electronic condenser microphone.
