Phono (MM/MC) Preamp: The Pro-Ject Phono Box USB allows you to
connect a turntable with either a MM (moving magnet) or MC (moving coil)
cartridge to today's home receiver's and amplifier which do not offer a
dedicated phono input. There is a button on the back of the unit which allows
you to switch between MM or MC mode.
Metal Case: The Phono Box USB's metal case shields the
electronics from vibration and electromagnetic interference.
Dual-Mono Circuitry: The Phono Box USB provides optimal channel
separation through dual-mono circuitry and low-noise ICs.
RIAA Equalization: The Pro-Ject Phono Box USB provides
amplification and RIAA equalization for both MM and MC cartridges.

RCA connections. A stereo RCA input connects your turntable, and a stereo RCA
output connects your home receiver or amplifier. RCA cables sold separately.
Ground Terminal: The Phono Box USB also has a turntable ground,
in case your turntable has a separate ground lead. This provides shielding to
the tone-arm and the sensitive circuitry in the turntable.
