preamplifier which is used is a dual-operation amplifier, ensuring an output signal with especially low
distortion.
3. Comprehensive protection circuitry:
1) Overheating protection: To prevent the amplifier from being damaged by overheating due to poor
ventilation or prolonged operation under difficult conditions, the overheating protection circuit automatically
switches off the output when the temperature of the amplifier reaches 90 °C, and restores normal operation
when the temperature falls below 90 °C.
