Feature:1. Class D: The Digital power amplifier board is a high performance Class D power amplifier with Class D efficiency for true high end sound quality. Maintain ultra low distortion for perfect sound quality.2. Versatile: Class D amplifiers feature for SAGAMI 7W14A inductors for clear and powerful sound, advanced integrated feedback design and proprietary high speed gate driver error correction (PurePath Ultra HD).3. Advertisement Mode: When total harmonic distortion is 10%, the sound amplifier board can drive up to 2 315W/4R loads and 2 150W (no clamp power)/8R loads, and has a 2 VRMS analog input interface that supports high performance DACs (eg, TI's PCM5242) seamless connection.4. High Power and Ultra Low Loss: Achieved by 85mR MOSFET and optimized gate driver scheme. This solution can significantly reduce idle losses (less than 2.5W) compared to traditional discrete implementations.5. Filter Capacitor: The main filter electrolytic capacitor adopts for Nixicon capacity 2200UF/63Vx2, 6 for Nixicon FW series 10UF golden sound input coupling capacitor. Other filter capacitors use the for Nichicon series.Specification:Item Type: Digital Power Amplifier BoardMaterial: PCBWorking Method: Class DStandby Current: 80mAWork Efficiency: >90%Channel: 2.0Still/Mute: Short Circuit Mute FunctionOutput Power:315W/4, 10% Distortion185W/8, 10% Distortion260W/4, Distortion 1%150W/8, Distortion 1%Frequency Response: 20Hz to 20KHzDynamic Range: >100dBSignal to Noise Ratio: (SNR)>111dBWorking Voltage: DC24-40V Switching Power Supply (Recommended Voltage 36V).Package List:1 xPower Amplifier Board
