Phono Preamp

Phono Box Black

Small but perfectly formed, the Pro-Ject Phono Box S is solid and relatively heavy, sporting a power button on the front and a set of inputs and a set of outputs on the back.

There’s a subsonic filter switch too, and if you want to get your hands dirty, then you’ll find switches on the bottom for selecting MM or MC operation and making adjustments to the gain and impedance.
