PORTABLE AUDIO NETWORKING SYSTEM

摘要

A portable audio networking system is provided that includes master devices and slave devices in communication over cables adapted to simultaneously transport a digital audio signal, DC power, and a data signal. Master devices are configured to receive a digital audio signal, distribute power, and transceive a data signal, and slave devices are configured to transmit the digital audio signal to master devices, receive the power from master devices, and transceive the data signal with master devices. Slave devices can include wireless audio receivers that receive an RF signal containing an audio signal from wireless audio transmitters. Master devices can include gateway interconnection devices that act as hubs and routers for the system. The reduction in the number of cables compared to traditional systems results in less weight for crew members to carry and easier setup of the system. Remote control of wireless audio transmitters is also enabled.
