7.4 PROTECTION CIRCUITRY
Both the power supply and the amplifier sections are equipped with several protection circuits. Power
supply protections aim to isolate a faulty section in electrical power system from the rest of the device
in order to prevent the propagation of the fault and limit device damages. They comprise overcurrent,
overvoltage and thermal protections.
Amplifier protections are triggered by audio signal current, voltage – by comparing input and output –
and NTC (Negative Temperature Coefficient) thermistors. A Peak Current Shut Down and a Temperature
Protection Limiter protect the output stage.
High frequency stationary signals, like steady sinusoidal signals – improperly referred to as continuous
or permanent signals – with high amplitude tend to stress the amplifier section of the modules as well
as the loudspeakers’ voice coils. When a high frequency stationary loud signal is fed into the amplifier,
a dedicated Limiter confines its mean current depending on its level and frequency.
