Pro-Ject Phono Box MM

Phono Preamplifier (MM)

Technology for good sound

Many current amplifiers do not offer a special phono input. Phono Box MM is the ideal solution for these hifi systems. It enables the connection of MM and high-output MC pickups and offers audiophile music enjoyment at an entry-level price. A modern circuit design avoids noise and distortion. The integrated shielding and the outsourced power supply hardly give external interference a chance. Due to its compact dimensions, the Phono Box MM can be placed close to the turntable. Both input and output sockets are hard gold plated to prevent corrosion. The Phono Box MM is connected to a line input (AUX etc) of the amplifier.
