BA series is adopted from Motorola Metal power transistors and designed with differential current power that is fully symmetrical pairs, giving it more headroom. The power supply uses a large current toroidal transformer accompanied with large capacity condensers provides unlimited energy that reaches full rated output power and stability.
The protection system consists of circuits and cooling fans, the cooling fans will automatically adjust its speed depending on the output power. The protection circuit is used prevent the switch spark noise to damage the speakers, it also provides short-circuit protection from the pressure flow. In addition the protection circuit is designed to automatically disconnect to protect the speaker when temperatures rise up to 85 degree Celsius and with abnormal DC output. The circuit protection does not cut dynamics without the distortion of the transient.
