Review on π Battery Power Supply Audio Mono Amplifier Module Board NJM386D LM386 by Kayla Rivera
Don't worry about home theater
Doesn't work. I've tried different settings and can't get the volume control to work. Any microphone plugged into it will get exactly the same gain as it would without this amp. No matter when it's on. Good only as a switch, nothing else.
- Input impedance: 10 kΞ© (max volume) Power supply operating voltage: 4-12 VDC.
- Some disadvantages
