Features
Phono (MM) Preamp: The Pro-Ject Phono Box MM allows you to connect a turntable with a MM (moving magnet) cartridge to a home receiver or amplifier without a dedicated phono input.
Metal Case: The Phono Box MM's metal case shields the electronics from vibration and electromagnetic interference.
Dual-Mono Circuitry: The Phono Box MM provides optimal channel separation through dual-mono circuitry and low-noise ICs.
RIAA Equalization: The Pro-Ject Phono Box MM provides amplification and RIAA equalization for MM cartridges.
RCA Connections: The Phono Box MM features gold-plated stereo 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 preamp 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.
Outboard Power Supply: The Pro-Ject Phono Box MM is powered by the included DC power supply. The external power adapter is separate from the phono preamp to further improve sound quality.
- Input: 100-240V AC~50/60Hz, 0.4A max
