AUDIO AMPLIFIER WITH SPEAKER PROTECTION AGAINST TRANSIENTS

摘要

An audio power amplifier with an amplifier for amplifying a received audio signal and an output for outputting the amplified audio signal. The audio power amplifier is controllable to assume an active state in which the amplified audio signal is fed to the output, and a mute state in which no amplified audio signal is fed to the output, and the audio power amplifier further comprises an input for receiving a control signal, and the audio power amplifier is adapted to assume the active state or the mute state in dependence on the received control signal. The power amplifier will assume its mute state if no control signal is received within a predetermined period of time.
