A&H dLive , 4-button wall-plate controller

The IP4 is a four-button wallplate controller from Allen & Heath, designed to give simple local control over dLive (as well as AHM and Avantis) mixing systems in installed audio setups. Each of its four illuminated buttons can be configured for mute toggling, preset recall, level adjustment, or source selection, with functionality set up via dLive Director (or AHM System Manager / Avantis Director) software. It connects over standard TCP/IP and is PoE-powered, fitting either Euro 50x50mm faceplates or US Decora-style backboxes depending on variant. It's aimed at installers wanting to give non-technical end-users straightforward wall-mounted control in spaces such as retail, hospitality, education, or meeting rooms, without needing a full mixing console interface.
