Abstract

Improvements in sound distribution systems. The improvements in sound distribution systems forming the object of the invention, whose purpose is to increase the services that such systems offer for frequently used routine operations, are based on the incorporation of a digital communications channel L1 which forms part of an area control module 2, an intercom and security module 3 and a central security module 4, with the consequent elimination of the individual control cables of the intercom areas, with the possibility of expanding the system by adding new area control modules 2 without the need to install new cables, which was necessary in previous sound distribution systems. This characteristic will enable future expansion of the system with new services without the need to set up special new control cables for each function, which enables users to expand their systems easily. <IMAGE>
