A method and a system for monitoring operation of at least one loudspeaker in a system comprising a plurality of loudspeakers connected in series on a same amplifier output in at least one loudspeaker chain driven by an amplifier board, the method comprising measuring a current consumed by the amplifier in an operating position of the plurality of loudspeakers, yielding a reference current; stopping the masking system into an idle position; emitting the reference signal, measuring an idle current consumed by the amplifier; and comparing the idle current with the reference current. The system comprises a microprocessor unit and a current measurement module, wherein the current measurement module is configured to measure a current drawn by the amplifiers and feed a resulting signal to the microprocessor unit; and the microprocessor unit generates an output signal to respective output channel.
A controller/amplifier board for loudspeaker chains, comprising:
A method for monitoring a loudspeaker chains system, comprising:
A method for monitoring operation of at least one loudspeaker in a system comprising a plurality of loudspeakers connected in series on a same amplifier output in at least one loudspeaker chain driven by an amplifier board, comprising measuring a current consumed by the amplifier in an operating position of the plurality of loudspeakers, yielding a reference current;
A method for monitoring disconnection of at least one loudspeaker in a sound masking system or a public address system comprising a plurality of loudspeakers connected in series on a same amplifier output, comprising measuring a current consumed by the amplifier in an operating position of the plurality of loudspeakers, yielding a reference current;
