2 X 450w Class Ab karaoke Power Amplifier in black face
Description
1, Protection Circuitry: Power amplifiers may include protection circuitry to safeguard against various faults or abnormal operating conditions. This can include features like overcurrent protection, overvoltage protection, short circuit protection, and thermal protection to prevent damage to the amplifier and connected devices.
2, Output Power and Efficiency: Power amplifiers are rated for their output power, typically measured in watts, and their efficiency, which represents the ratio of the output power to the input power. Amplifiers with higher efficiency convert a larger portion of the input power into the amplified output, resulting in less power dissipation and heat generation.
