DA-212K Pro 2-Channel High-Efficiency Class TD Power Amplifier
● Employs a high-reliability switching power supply design, undergoing extensive stability and stringent condition testing to ensure continuous full-power output.
• Large-capacity energy storage capacitors provide consistent and nuanced sound performance even during continuous high dynamic range output.
• A unique and improved cooling system design effectively enhances heat dissipation by 30%. Cooling airflow filtered through a dust cover passes only through the heat sinks requiring cooling, improving heat dissipation while preventing dust and smoke from contaminating the circuit boards and causing malfunctions, keeping the amplifier operating at room temperature for extended periods.
• A specially designed high-current short-circuit protection design ensures that the amplifier will not output a DC signal, protecting the subsequent speaker system.
• Features Sensitivity adjustment in three levels: 0.775V, 1V, and 1.4V.
* Perfect protection functions, including surge protection during power-on/off, DC protection, limiting protection, overload soft protection, and over-temperature protection.
* Simple and stylish appearance design, showcasing the characteristics of a high-quality power amplifier.
