The internal layout of the entire unit is scientifically designed for air flow, with high-efficiency aluminum heat sinks and variable-speed cooling fans to ensure the amplifier operates at lower temperatures. A comprehensive protection circuit ensures the safety of the equipment, including DC output protection, overload protection, short circuit protection, and overheating protection. It features a design with low distortion, wide frequency band, low noise, and clipping distortion limiting circuits. The use of an advanced full-bridge switch-mode power supply system with a comprehensive protection circuit.
