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
- Input: 100-240V~50/60Hz,
- Output: 15V - 500mA (18V)
