CLASS A: This position provides Class A bias to the output stage therefore ensuring the optimum performance of the amplifier during all listening events. Class A amplifiers run hotter than Class AB amplifiers, hence our specially designed and distinctive heat sinks. Operating the amplifier in Class A necessitates two precautions that should be observed.
1.On switching to Class A, the temperature of the amplifier will quickly increase and the amplifier will become quite hot. Once again we remind you to ensure that you have left adequate space around the amplifier for ventilation. Ensure that no objects are resting on the amplifier and check that the heat sink (cooling fins) are not obstructed in any way.
2.The power required from the mains supply in Class A is approximately 500 watts, similar to a small electric heater. The amplifier should not be connected to a wall outlet that is shared with other heavy current appliances such as heaters or electric motors. If in doubt, check with your Plinius dealer for advice.
