Item Type: Power Amplifier Board Parameter Index: DC=50V, When R=2Ω, THD+N=10%, P=600W When R=4Ω, THD+N=10%, P=350W When DC=50V, R=6Ω, THD+N=10%, P=250W When DC=50V, R=8Ω, THD+N=10%, P=200W Total Harmonic Distortion (THD+N): <0.1% Signal to Noise Ratio (SNR): >100dB Input Impedance: 20KΩ Output Offset Voltage: <150mV Voltage Gain: Adjustable Conversion Rate (SR): 50V/us Frequency Response Range: 20Hz--20kHz Power Supply Range: DC20--DC50V PCB Size: Approx. 111.6 x 103.5mm / 4.4 x 4.1in Crossover Point: 60HZ Product Description: The DC input voltage of the board is from DC 18V to DC 50V. The recommended range is 24-45V and the current is above 6A (the larger the better). You can also use a transformer and a rectifier bridge to filter. The transformer is within 15V-33V. The input signal can be left and right 2 inputs or only mono input 1、TAS5630 Class D amplifier can be driven. Under DC48V 2Ω load, it can provide 600W output power, and under 4Ω load, it can provide 350W output. 2、Using HD technology and TI advanced closed?loop architecture, good performance. 3、Can realize high?definition media playback and ultra?low distortion for blue?ray home theater systems, stand?alone home theaters, and professional audio systems. 4、The analysis and details are excellent, the driving force is very strong, and the power consumption is very low. 5、Lossless HD sound quality, soft and without obvious harshness, give you the perfect listening experience. 1 x Power Amplifier Board 1 x Cable
