Abstract (en)
The system has amplifiers (1, 2) comprising outputs (11, 12) connected to ends (EL1, EL2) of a public address system line (L) servicing a set of loudspeakers (HP). The line is self-controlled by a line control module (7) and a short circuit or power outage managing module (8) for reconfiguring and signaling in case of defect on the line. The module (7) has detectors connected to the line and a CPU, and cables connect the loudspeakers to the associated amplifiers.
