preamplifiers

Initial gain stages

Preamplifiers are electronic devices that boost weak audio signals before they reach a main amplifier.

A preamplifier prepares the signal—from a turntable, microphone, or instrument pickup—so it's strong enough for further processing without introducing noise.

In audio setups, the preamp handles initial gain and often tone controls: The turntable needs a phono preamplifier.
