NetSpire™ Long Line Public Address systems typically include a number of remote Gateway units which are located on a WAN or LAN. Communication from operators is routed via the Communications Exchange and the Gateway units are responsible for queuing and prioritising LLPA and DVA announcements. Either the Gateway units' embedded amplifiers, or external amplifiers are used to provide the audio output to speakers.
