Low Impedance Microphone Amplifier
This is the circuit diagram of low impedance microphone amplifier. The circuit designed for use with low impedance (~200 ohm) microphones. It will work with regulated voltages between 6-30VDC. If you don’t build the impedance adapter […]
Pre-Amp + Tone Control with TDA1524A
This is a low noise and distortion pre-amplifier and tone control circuit in one module. Using a special IC TDA1524A, this simple circuit is easy to build and will drive most of power amplifier. Schematic diagram:
HiFi Audio Pre-amp
This is a HiFi pre-amplifier circuit diagram with low noise output. Very wide range frequency from about 10Hz until up to 100Khz? will be gained by this preamplifier for maximum audio performance. This circuit uses BC550C […]
