Product Research

Features

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.

A/D Converter with USB Output: The AD Box S2 Phono features a 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 cable not included). The unit supports sampling frequencies of 32, 44.1, and 48kHz. Your computer must have a suitable recording program installed (the Phono Box USB does not provide built-in recording software).

Note: Runs on Windows (XP/Vista/7/8) and Mac OS X operating systems with automatic recognition and no additional drivers required.

Outboard Power Supply: The Pro-Ject AD Box S2 Phono 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: 5V - 1A

Metal Case: The AD Box S2 Phono's metal case shields the electronics from vibration and electromagnetic interference.

Q
Crutchfield asked: Why did you buy this?

Setting up an analog stereo system to a first generation AV analog receiver without MC phono input. Like the digital USB function to digitize 33 1/3 LPs, icing on the cake. [ J  Sep 03, 2019 ]

Needed a pre amp. This one looks good [ Michael  Feb 05, 2019 ]
