A standalone phono preamp is a separate component that connects between a turntable and a line-level input, giving installers more flexibility for cartridge matching, system layout, and future upgrades. A phono stage built into an integrated amplifier combines that signal processing with amplification in one chassis, which can simplify connections and save equipment space while still supporting compatible moving-magnet or moving-coil cartridges, depending on the design.

Moving magnet (MM) and moving coil (MC) cartridges produce different signal levels and loading requirements, so choose a home audio phono preamp that supports the cartridge type in your turntable. Models with selectable MM and MC inputs, gain settings, or cartridge loading options provide more flexibility when matching a phono preamp to current or future cartridges.

Look for phono inputs that match your turntable cartridge, such as moving magnet (MM) or moving coil (MC), and connect the preamp’s line-level RCA outputs to an amplifier or receiver’s line, auxiliary, or dedicated power-amp input. For powered speakers or equipment with balanced connectivity, choose a phono preamp with the corresponding RCA or XLR outputs, and confirm that the speakers accept a line-level signal.

Gain boosts the low-level signal from a moving magnet or moving coil cartridge so a phono preamp can feed a line-level input without excessive noise or distortion. Impedance and loading controls adjust the electrical match between the cartridge and phono preamp, which can affect tonal balance and output, so choose settings that align with the cartridge specifications.
