Specification:
Item Type: Digital Amplifier Board
Material: PCB
Main Technical Parameters:
Operating Voltage Range:
DC single power supply 12-24V (current 3-4A, or 19-24V 4-5A, such as high power requirements of 20-24V 8-9A or more). If AC transformer power is used, it must be converted to DC power by adding rectifier filter. Only then can it be connected. Note that the DC no load voltage should not be greater than 25.5V (this is very important)
Input Sensitivity: 600-800mV
Frequency Response Range: 20Hz-20KHz
Speaker Impedance: 2-8Ω
Output Power:
Power 12V 8Ω Speaker >10W 4Ω > 20W 3Ω > 25W 2Ω > 30W (Same for Left and Right Channels)
19V 8Ω > 24W 4Ω > 45W 3Ω > 60W 2Ω > 75W
24V 8Ω > 35W 4Ω > 75W 3Ω> 95W
