Abstract
Improvements in multipurpose systems for distributing sound or any low frequency signal capable of having several simultaneous uses. The purpose of the improvements in multipurpose systems for distributing sound or any low frequency signal capable of having several simultaneous uses covered by the invention, is to increase the services that these systems offer for frequently used routine operations, by using their infrastructure. By means of the incorporation into a station 1 for supplying the whole system and adapting the audio signal of the sound source to the whole installation, of a connection module 2 between an entry-phone and the multipurpose sound distribution system, a signal generator module 3, which announces different calls via the sound distribution system, is set up together with a system of transmitting universal control signals generated by infrared controllers 4, for being able to operate the equipment from any sound distribution installation area, an intercom system with automatic answering 5, 5' and a communication system between a transmitter or several receivers, all connected to distribution lines L1 to L4.
