    D*AP8 Setup GUI – EVENTS – Overview The D*AP8 offers a sophisticated event management system. The event management system performs Actions. These Actions are built from Events. Actions may be triggered manually (via the X*AP RM remote panel Hotkeys), semi-automatically (triggered by network commands or GPIs) and automatically (triggered by changes of parameters and/or the internal status) or as a combination of all three.

    D*AP8 The D*AP8 has two different action types: Event Actions executes the predefined events Bypass Actions executes pre-defined bypass scenarios, independent of the bypass events An action runs like a flip-book inside the D*AP8. This powerful technology spans from simply recalling a certain system parameter over speaker or Dolby specific parameter combinations (household name: "Preset") to the complete reconfiguration of the D*AP8 including all signal routing, processing parameters and so forth.
  • Page 92 D*AP8 Setup GUI – EVENTS – Triggers – Sources – Network Network triggers are based on the EmBER+ protocol from Co. l-s-b http://www.l-s-b.de/en. The D*AP8 receives such triggers over the TCP/IP network. The triggers are issued by a device that has implemented the EmBER+ protocol (e.g.
