What is it? A USB device offering ethernet control of Crown XTi, CDi and DSi Series amplifiers from an iPad/iPhone app. Details The USBX is designed for setting up, monitoring and troubleshooting amplifiers across a wide variety of applications including small to medium fixed installations, mobile PA systems, movie theaters and other venues. Connected via an AC outlet, up to eight compatible products can be Wi-Fi controlled from the USBX using the ‘Powered by Crown’ app for iPad or iPhone without the need for a separate wireless router. The app allows wireless control and monitoring of both Crown Ethernet-enabled devices and JBL speakers equipped with DrivePack DPDA built-in amplifiers. And another thing… The Powered By Crown app uses the same protocols as Harman’s HiQnet System Architect, allowing users to import custom control panels from System Architect for added functionality.
