Features
Phono (MM/MC) Preamp: The Pro-Ject Phono Box S 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 S's metal case shields the electronics from vibration and electromagnetic interference.
Audiophile-Grade Capacitors: Carefully selected amplifier modules and audiophile-grade polypropylene capacitors make it possible to enjoy your valuable vinyl collection like never before.
Dual-Mono Circuitry: The Phono Box S provides optimal channel separation through dual-mono circuitry and low-noise ICs.
RIAA Equalization: The Pro-Ject Phono Box S provides amplification and RIAA equalization for both MM and MC cartridges.
Controls: The Phono Box S features various controls to make sure your turntable sounds it best.
- Gain Levels: The phono preamp's gain level (40/43/60/63dB) can be adjusted to match the level of your MM/MC turntable.
- Input Impedance/Capacitance: You can adjust the phono preamp's input impedance (10/100/1000 Ohms) and input capacitance (100/200/320/420pF) to the setting that best suits your turntable. The input impedance is locked at 47k Ohms for MM turntables.
- Subsonic Filter: A switchable subsonic filter prevents your amplifier and speakers of ultra low rumble below 20Hz (-12dB).
Connections: The Phono Box S features a stereo RCA input and output, as well as a ground terminal.
- RCA: The phono preamp 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 phone 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 S operates off of standard household AC current, using the supplied AC power adapter. The external power adapter is separate from the phono preamp to further improve sound quality.
- Input: 100-240V~50/60Hz, 0.6A
- Output: 15V - 500mA (18V)

Clean clear crisp... New life to my records. Pops and hisses are covered by music, they are still there but the music is the highlite. Adds clean volume with full body. Crutchfield helped with the setup... and every record sounds great.
