사운드 증폭기 입니다. 모노이고 DIY키트입니다. 히트싱크는 별도로 구입한거 연결했습니다.
추천하는 전원은 12V 입니다.
Output Power: Maximum 18W
Supply Voltage: DC 9V-24V( recommended DC 12V, this voltage to the heat sink requirements are very low;
Maximum supply of this board is actually up to 40V, but you need to change the board’s own electrolytic
capacitor C1, the capacitor voltage value is higher than supply voltage can be use. )
Static Current: about 25mA( disconnect to tone, connect to 8Ω speaker, 12V power supply. )
Speaker Impendance: 4Ω-8Ω
Total harmonic distortion: THD 0.08%（Po=0.1 to 14W，RL=4Ω）
Heat: The higher the supply voltage, the great the volume, the higher the heat
