6.5mm Dynamic Microphone 3.5mm Condenser Microphone Amplifier Headphone Amplifier Music Audio Preamplifier Mixing Board MA-2

The dynamic amplifier is about 100 times, the capacitor is about 22 times, and the music part is about 5 times. The mixed output can drive the earphones. Note that the input signal voltage * magnification cannot be higher than the power supply voltage. Please choose the supply voltage reasonably. The higher the voltage, the larger the signal. It is not easy to clip. If the signal is not very large, it can work even if the voltage is lower. Please use a high-quality low-ripple power supply, as the power supply is not good enough to easily produce hum. The power interface is DC5.5*2.1, inside + outside - not include the power supply . package include: 1pcsMA-2
