Pro-Ject Phono Box MM Phono Preamplifier
High-precision MM phono preamp for bringing out the best in your vinyl setup

Overview
The Pro-Ject Phono Box MM is a compact analog phono stage designed specifically for moving magnet (MM) cartridges. It’s ideal for turntables and hi-fi systems that lack a built-in phono input. Built in Europe, it delivers audiophile-level sound and accuracy without breaking the bank.

Sound & Design
With precise RIAA equalization and low-noise circuits, the Phono Box MM offers warm, detailed, and non-fatiguing playback. Dual-mono circuitry ensures excellent stereo separation, while a metal chassis and external power supply help shield internal components from electromagnetic and vibrational interference.

Connectivity & Usability
The unit has one pair of RCA inputs and one pair of RCA outputs. Its small footprint makes it easy to place close to your turntable to reduce cable-run noise. Gold-plated RCA sockets help maintain signal integrity.
