Audio input modules are used to connect paging and/or music sources to the network control panel. They offer analog to digital conversion and automatically adjust for input sensitivity. Each panel accepts any combination of three inputs like auxiliary (AIM-2A), microphone (AIM-2M) and telephone (AIM-2T). The paging and music functions play over the same set of loudspeakers as the sound masking, but their zoning and settings are independent, so you never have to compromise. The amplification and equalization technology is already integrated into the hubs, reducing the cost, energy and space typically needed for audio equipment. Users can create customized zones whenever and wherever required using page director software.
