MultiPlayer are network-based allowing a properly credentialed operator to configure and control the system using any standard web-browser. Once configured the AMC is able to automatically gather emergency information from a variety of sources by monitoring data feeds over serial or TCP/IP connections and applying input filters to retrieve the appropriate information for processing. In addition the operator may load a pre-produced audio file, type message text, or to really speed things up, cut and paste the message text for rapid Text-To-Speech conversion. The AMC then handoffs the selected file or the TTS audio file, to the MultiPlayer readying it for playback. When activated the Main Program audio plays the preset audio file (for example a two-tone burst or a pre-recorded announcer indicating "Additional audio information is available on your secondary audio channel" then returns to normal, simultaneously the Secondary Audio Program is switched in and plays it’s audio message the two times as the rules require, or a user defined number of iterations, after which it returns to normal SAP audio.
The MultiPlayer’s flexible design allows it to be configured to use its internal switching or originate the audio signal(s) for switching or embedding by downstream devices, including independent GPO’s to trigger these devices. The four independent channels can be configured for mono-analog or stereo AES and channels can be "bonded"or grouped together to create multi-channel audio configurations. The AMS is an extension of technologies Digital Alert Systems has developed in response to the supporting both IPAWS EAS/CAP messaging requirements and the diverse needs of America’s broadcast television industry. Understanding the importance of accurate record keeping the AMS maintains a series of comprehensive logs for monitoring inputs, debugging issues, and a reporting method for proving compliance.
