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 speakers with power, as well as digital audio signals, and bi-directional 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.
