External Control Plus. Designed for use with Radius, Prism, Edge, and Solus NX DSPs. Especially useful in conferencing and paging applications. Each of the 8 flexible analog control inputs may be configured for 1 potentiometer or 2 switches. The 16 logic outputs may be used to drive LEDs, trigger external relays, or control contact closure ports. Either of the 2 RS-232 ports may be configured to issue or receive commands to or from third-party control systems. Utilizing PoE, xControl may be mounted where convenient and connected to a control network using a single cable. The half-rack form factor conserves rack space, or if preferred, the xControl may be surface mounted at point-of-use.
