Most microphones’ output signals are weak and cannot be directly connected to some other circuits. Also, some microphones require DC power supply or high impedance inputs. Here is a dual (stereo) preamplifier for microphones that can be used with a wide variety of circuits, including analogue-to-digital converters (ADC), microcontroller (MCU) kits and single-board computers such […]
