HiFi Audio PreAmp Circuit TL072

A preamplifier (preamp) is an electronic amplifier that prepares a small electrical signal for amplification or further processing. A preamp is often placed close to the sensor to reduce the effects of noise (noise) and interference (radio frequency).HiFi Preamp used to increase the signal strength to drive a cable to the main instrument without significantly lowering the signal-to-noise (SNR).
