Our take on the Pro-Ject Phono Box MM

Get back in touch with your record collection

Do you have a turntable, but no phono input on your receiver or shelf system? No problem — just hook up the Pro-Ject Phono Box MM preamplifier inline between your record player and any of your receiver's aux inputs, and you're ready to enjoy your LP collection all over again. This preamp's clean, simple design takes advantage of high-quality, low-noise circuitry to give you the warm, richly detailed sound that vinyl is famous for, at a bargain price.

Listening to my vinyl again! Does the job as advertised. I am not an audiophile so it sounds great to me :-).

Hands-on research

Product Research


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
  • Output: +/-18V DC - 0.5A

2 questions already asked

It looks like the R1000-EDT is a moving magnet cartridge, so this should work for you. I would recommend reaching out to an Advisor by phone or online chat first to double check though. [ Jeff  Jan 09, 2014 ]  Staff
Thanks for your question. For information on determining the type of cartridge your turntable has I would recommend trying an internet search for the model number. Yo could also reach out to an Advisor by phone or online chat. They will be able to help determine the type of cartridge and help you get the best gear for your system. [ Jeff  Dec 28, 2013 ]  Staff
