What “phono preamp” means (en-US)
A “phono preamp” (short for phonograph preamplifier) is an audio device that boosts and equalizes the signal from a turntable’s cartridge so it can be played through a standard line-level input (like most AUX, CD, or receiver inputs). Turntables produce a relatively low-voltage signal, and the preamp amplifies it while applying the correct RIAA (or other) equalization curve to restore the intended frequency balance.

Why it’s needed
Most turntables do not output a strong enough signal to connect directly to typical speakers or line inputs. A phono preamp increases gain and corrects the recording’s frequency response. Some turntables include a built-in phono stage; in that case, you usually connect to a line input and skip an external phono preamp.

Key things to check when choosing one
1) Cartridge type: Many phono preamps support either moving magnet (MM) or moving coil (MC). Some are switchable; others are dedicated. 2) Gain and loading: MC cartridges often require specific gain and impedance loading; MM cartridges also benefit from correct loading. 3) Equalization standard: RIAA is common in the US; other regions may use different curves. If you’re unsure, match the preamp to your cartridge specifications.
