Overview:
DA43K2 class d audio amplifier designed to deliver high power, high efficiency and 2 ohms stable performance for subwoofer.
Amplification
Class d amplifier board with Gallium Nitride transistors and high efficient cooling system with low heat provide high output, high fidelity and stable performance.
Power Supply
DA43K2 subwoofer amplifier adopted power factor correction (PFC) technology provides universal working voltage, and delivers constant power to the loudspeakers regardless of AC mains voltage fluctuations and eliminating the need for market-specific power supplies and associated reliability issues.
Monitoring Display
DA43K2 class d audio amplifier integrated a temperature and voltage monitor that allows the working temperature and voltage can be seen.
Comprehensive Protection
Under voltage, DC, Over temperature, Over load limiter, short protection.
