Abstract
Simultaneous distribution system of several sound signals using as a physical support any network of pre-existing electrical installation, characterized in that to any electrical conduction network, modules are independently connected for the distribution of sound, comprising a transmitting station to which the original sources of sound, such as radio, turntables, etc., said central being responsible for coupling the sound signals after processing thereof, to said electric conduction to be sent to an indefinite number of receivers, also connected to the same electrical network, each one incorporating a system of remote control of connection and disconnection of the sending station, the elements of selection of the desired sound source, and equipment necessary for its adaptation to a loudspeaker with the corresponding controls of volume and tonality.
