Phono Preamp (MM/MC): The Pro-Ject AD Box S2 Phono 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.
Dual-Mono Circuitry: The AD Box S2 Phono provides optimal
channel separation through dual-mono circuitry and low-noise ICs.
RIAA Equalization: The Pro-Ject AD Box S2 Phono provides
amplification and RIAA equalization for both MM and MC cartridges.
RCA Connections: The AD Box S2 Phono 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 AD Box S2 Phono 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.

built-in A/D converter (Burr Brown PCM2904 16-Bit Delta Sigma) with a mini-USB
(type-B) output to record your vinyl music to a Windows PC or Mac computer (USB

Box USB does not provide built-in recording software).
