Notice: This power amplifier board is pure bass output(Subwoofer), no midrange and treble output.
The main parameters:
Power supply: DC6.5-16V (depending on the required output power), eg. power adapter, switching power supply, battery, etc., the recommended current is more than 3A.
Output power: VDD = 7.4V RL = 2 O 12.5W
Output power: VDD = 9.0V RL= 2 O 18W
Output power: VDD = 12V RL = 4 O 20W
Output power: VDD = 16V RL= 4 O 32W
In order to obtain a more shocking effect, it is recommended to use a 4-5 inch, 4-6O 20-50W subwoofer speaker.
In order to obtain a larger power, it is recommended that the power supply be not lower than 9V.
Upper crossover point: 110Hz.
PCB material: FR-4 glass fiber board, thickness: 1.6mm.
Board size: 1.57x1.65x0.78inch (LxWxH), excluding potentiometer handle length (Pot. protruding length 0.59inch).
The potentiometer mounting hole diameter needs to be 0.28inch.
Power input interface: 5.5*2.1DC socket or pad of welding wire
Audio input interface: 3.5mm plug or pad of welding wire
Onboard fixing hole diameter: M3
Package Included:
1 x Subwoofer Amplifier Board
