It will work with stabilized voltages between 6 30VDC. If you don’t build the impedance adapter part with T1, you get a mic amp for higher impedance microphones. A Mini Microphone Preamplifier | Open Electronics The circuit itself is pre amplifier and comes equipped with a microphone that picks up the signal. This is amplified about 480 times by using a common operational amplifier. We emphasize that the module is a preamp: before being connected to a speaker the signal requires an additional pass through a power amplifier stage. Dynamic Microphone Preamplifier circuit using C945 If friends are looking Dynamic Microphone Preamplifier circuit is high quality. So the low noise signal. I suggest this circuit because It use the three transistor (2SC945, or 2C1815 or 2SC828) is main Which typical transistor amplifier with a low noise this circuit, too. Preamplifiers Audio Preamplifier Circuits SIMPLE AUDIO PREAMP: This easy to build circuit provides good gain to weak audio signals.
