Abstract
The method for checking loudspeakers comprises the steps of emitting a pulse over an electrical connection with the loudspeaker; measuring the electrical resistance over the connection; determining the state of the loudspeaker according to the measured resistance; and triggering a corrective action depending on the determined state of the loudspeaker. The claimed method further comprises the steps of associating a plurality of amplification systems to different subsets of the plurality of loudspeakers; assigning different signals to be emitted by different loudspeakers for each of a plurality of control signals; and storing parameters representing the signals to be emitted in each amplification system. When a control signal common to the different amplification systems is received, the amplification systems cause the loudspeakers to emit the different signals and the corrective action comprises memorizing the parameters representing the status of the loudspeaker.
