Audio power amplifier
1. GA series is switch mode power supply, 2U rack, the weight is light but power output.
2. Its special cooling method (two speed fans, rear to front air flow) makes the cooling speed much faster.
3. With high effective Class-H circuit, the perfect protecting system (Short circuit, thermal, overload, clip limited, DC voltage, ultrasonic and RF) makes the product more stable; SMT.
