Understanding the Phono Stage on a Turntable


The phono stage plays a crucial role in bringing your vinyl records to life. Hidden within the grooves of a record lies an electrical signal that captures all the nuances of the music.

This signal is very faint, and without amplification, it can’t move speakers or headphones. Enter the phono stage: This audio component steps up to amplify these minute signals. It prepares them for further processing by your sound system.

Crafted with care, the phono stage delicately boosts the low-level output from moving magnet (MM) or moving coil (MC) cartridges. It does not simply make everything louder. Instead, it performs a precise act of balance. It does this using RIAA equalization—an essential curve. This curve restores fidelity to the original recording. It adjusts bass and treble levels correctly.

The final result is a line-level signal robust enough to flow through RCA cables without introducing noise or distortion. It can then reach receivers or powered speakers. Each turntable setup benefits from this pivotal piece. Whether you have built-in preamps will depend on personal preference and equipment compatibility. You may opt for separate units instead. Knowing its function is key to crafting your ultimate vinyl playback system.
