Abstract

Intercom installation with reversible loudspeakers, consisting of more main stations, characterized by the fact that each main station is equipped with an amplifier so that the reversible loudspeaker of the transmitting station is inserted at the entrance of the same amplifier, while the output of this is connected to the loudspeaker of the position receiving the communication, thus avoiding the use of lined connection cables.
