Digital Speaker System Bus

The digital speaker system bus (DSS bus) replaces speaker lines known from 100 V systems. It feeds the connected components, e.g. integrated amplifiers and powered speakers with power, as well as digital audio signals and bidirectional control data in real time via one single standard CAT5 or J-Y(ST)Y cable.  

The DSS bus combines central network structures with a bus architecture, saving on cabling and wiring time and eliminating the need for additional hubs and routers even for the largest networks. VARIZONE VAB-Line VAB1 Controller
