Features: Use genuine original TDA7498E. The main filter uses 12 high-quality electrolytic capacitors to effectively reduce ESR and improve transient response The output magnetic ring adopts high-quality high-current red-ring inductor, and the low-pass filter has better performance, which can cope with the output of high power. Cooler with fan keeps the amplifier in top shape without thermal distortion. Adopt high-quality original parts is not only a -guarantee of safety and quality, long service life, but also a strong -guarantee that the actual performance can reach the design goal. Specifications: Material:Metal Operating Mode: Class D Static Current: 50mA Operating Efficiency: 90% Rated Output Power: 2x160W Frequency Response: 20Hz to 20KHz Operating Voltage: for DC 20V to for DC 36V Recommended Supply Voltage: for DC 24V Maximum Output Current: 5A PCB Board Size: Approx.12280mm/4.8x3.15in Speaker Parameters: 6-8 ohms Note: Please allow 1-2cm errors due to manual measurement,pls make sure that you do not mind before you order.
