Pro-Ject Phono Box MM Reviews
Average Customer Review(s):
Thanks for submitting your review
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

Why did you buy this?
Per adviser Tine saying it will work with my MMC EN20 B&O 3400 Turntable. [ Patrick O. May 08, 2018 ]
Needed for new Sony A/V receiver. Phono preamp is no longer on the back of the unit. [ Mark Mar 21, 2018 ]
I do have a receiver with phono input. However I found that when I play a record, I lose volume / out put power when compared to audio out put of the other components like the cd player or satellite radio, tuner and dvd. It was suggested that I get an independent phono pre- amp and plug it into to the reciever as one would do as if the receiver did not have a phono input. So I am waiting fot this project pre amp to see if I get a fuller sound as I do with my other components. Hope it works! [ CHRISTOPHER Mar 10, 2018 ]

3 questions already asked
Yes. This box solved the exact same issue for me. [ DAVID Feb 01, 2018 ]
Yes, your Ortofon cartridge is a MM (Moving Magnet) cartridge. You need an MM phono pre-amp like this one (which is great, by the way). Plug your phono pre-amp into any of the line outputs (marked CD, Aux, etc.). You'll be off and running. [ Michael Jan 31, 2018 ]
Yes. I have the same turntable and a Yamaha amp and use thr same project pre amp. [ Paul Jan 31, 2018 ]
What input options does your receiver have? I previously used a Pioneer Receiver that has TV/SAT inputs, and I plugged my turntable into that. I would think you would be able to plug this into whatever input you had been using for a turntable. (Unless it's a USB only turntable?) [ Alicia Jan 31, 2018 ]
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
