## Overview

The Pro-Ject Audio Phono Box MM is a compact, high-performance phono preamplifier designed for moving magnet cartridges. Featuring dual-mono circuitry, low-noise integrated circuits, and gold-plated RCA connectors housed in a vibration-resistant metal case, it delivers superior sound clarity and minimal distortion. Perfect for modern setups lacking dedicated phono inputs, it transforms your turntable experience with easy plug-and-play installation and audiophile-grade audio fidelity.

## Description

Since many modern amplifiers no longer have a dedicated phono input, the phono box mm from Pro-Ject is the perfect addition to your turntable setup. Compatible with nearly any moving magnet cartridge, the phono box mm gives you a superb audiophile music experience at an entry-level price. The utilization of advanced circuitry keeps noise and distortion extremely low, and the metallic case and outboard DC power supply keeps the unit free from electromagnetic interference. Since it's only slightly larger than a pack of playing cards, the phono box mm can be placed nearly anywhere. The RCA input and output sockets are gold-plated to preserve sound quality and can be connected directly to any line-level input (aux, CD, Etc.) on your amplifier.

Review: Rediscovering old friends with the help of a new tool - I've been slowly upgrading my vinyl setup over two years. I started with a mediocre at best Pyle Pro turntable and preamp. I got rid of it when I realized I couldn't turn the volume up anywhere near a satisfying level without starting a feedback loop. I upgraded to an ATLP120 which is still going strong. I used the built in preamp for a time, but when I upgraded to an Ortofon 2M Blue cartridge, the sound was awful. So I did the deed and took the preamp out. For the last year or so I was using the Pyle Pro preamp with the straight output from the cartridge. At this point the mains power to the turntable powered only the platter. The cartridge output went straight to the preamp. The sound was acceptable and decent, until it got really crackly sometimes. It was not due to the records being played because they sometimes sounded fine, and other times they did not. I decided it was time to upgrade to a MM specific preamp. I mostly just wanted the cutting in and out to stop, and I wanted the volume considerably loud without the increasingly annoying hiss I was noticing. I also suspected that the left channel was being slightly favored. My suspicions were confirmed when I hooked this ProJect Preamp up. Not only did it eliminate the aforementioned issues, but it improved on the sound in a way I could not have imagined!! I can't wait to go back through my Genesis and Floyd albums with this thing. Fantastic on speakers and headphones!!! Worth every penny!
Review: Perfect pair for Pro-Ject turntable! - I bought a Pro-Ject turntable,the Carbon 2M, so this is like a match made in heaven. It was crazy easy to set up (plug and play pretty much) and it immediately corrected audio issues as well as gave me the power of sound that having a turntable requires. This was an afterthought for me as I had purchased a nice player and a nice sound system only to realize I forgot you needed a preamp to make it all sound great and loud. This is the most satisfying purchase i've made in years because of how easy it is to use and effective it is.

## Questions & Answers

**Q: How can i tell if my pioneer pl-460 is mm or mc?**
A: The cartridge you're using should be marked MM (moving magnet) or MC (moving coil).  Nothing I've found online specifies.  MM is the safer guess here because MC cartridges tend to be high-end and they're not as widely distributed.  This one does not appear to be high-end.  If it is MM, you'll know as soon as you use the MM pre-amp:  when your turntable is plugged into a MM-compatible pre-amp (such as the Pro-Ject Phono Box), the sound output will be pretty close to that of a CD player plugged into the same amplifier.  If you discover they're not compatible, you should be able to get a refund or exchange one the Phono Box.

**Q: Just to be clear, my AVR (Onkyo tx-nr535) doesn't have a phono input. Do I connect the turntable to this device and plug this device into my AUX port?**
A: I believe that this would work. I'm using it with it Denon AVR and running it thru the aux input using an MM cartridge. I don't think this would work if you're using a moving coil cartridge.

**Q: Do i need to buy this for yamaha A-s801 integrated amp or that amp has a phono**
A: If you have the integrated amp look on back and see if you have phono inputs - if you don’t have it try googling it to see specs

**Q: Can i play vinyl from my B&O 3400 turntable & cartridge thru a vizio soundbar model# s4251w-b4? Do I need to use my pyramid sea2500x preamp too?**
A: Unless you are using an amplifier with a phono input, you will need a preamp.

### ⭐⭐⭐⭐ Works well and does its job
*by B***Z on December 29, 2025*

Works well and does its job. Amplifies a MM signal and connects to line-level inputs on a audio preamplifier. Rugged steel enclosure and ground connection that allows you to ground your turntable to the signal ground connections. Disappointing to find TL071 opamps compared to one with better performance like the NE5532.
