Notes on protection circuits:
These amplifiers are equipped with different protection circuits to prevent any damage to the amplifier
itself or the speakers due to improper operation circumstances.
1. Overheat- For low mechanical noise emission, the built-in fan operates at low speed as long as
the internal heat sink keeps cooler than 55 degrees Celsius. The fan will speed up to maximum
speed when this temperature is exceeded. When the heat sink temperature exceeds 90 degrees
Celsius, the amplifier will shut down the outputs to avoid overheating. The outputs will be
automatically re-activated when the heat sink comes below 70 degrees Celsius.
2. DC on output- When DC is detected on the output, the amplifier will shut down the outputs to
avoid speaker damage.
3. Short circuit on the output- When a short circuit is detected on the output, the amplifier will shut
down the outputs to avoid damage to itself.
