Preamplification is the initial stage of signal amplification in an electronic system. Its primary purpose is to boost a weak input signal to a level that is more suitable for subsequent processing stages, such as main amplification or analog-to-digital conversion. This is particularly crucial for signals originating from sources that naturally produce very low voltage outputs, such as microphones, musical instrument pickups, or certain sensors.
A preamplifier increases the signal voltage without significantly altering its waveform or introducing unwanted noise. The
In audio systems, preamplifiers are essential components found in mixing consoles, audio interfaces, and standalone devices.
