What's in the box
Product 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.

Good sound from sound technology
Today, many amplifiers do not have a specific phono cartridge input. Phono Box MM is an ideal phono preamplifier for these hifi systems. Phono Box MM accepts MM and high-output MC cartridges and offers an audiophile music experience at an entry-level budget. Advanced circuitry keeps noise and distortion at a surprisingly low level. The metal case shielding and an outboard DC power supply leave no risk for external interference. Because of its small casing, Phono Box MM can be placed near the turntable. Input and output sockets are gold-plated for preservation of quality. Phono Box MM can be connected easily to a line-input (AUX etc) of your amplifier.
Features
- Amplification and RIAA equalisation for MM and High-Output MC cartridges
- Metal case shields the electronics from vibrational and electromagnetic interference
- Special low-noise ICs used
- Optimal channel separation through dual-mono circuitry
- Gold plated RCA connection sockets
- DC power supply (< 1 watt standby power)
- Small size allows installation close to record player

I just upgraded to the Pro-Ject Debut Carbon, which requires an external preamp, and now it's put to good use. I love it.
Obviously it's a bit difficult to isolate what the preamp specifically brings to the table, because to use it, I introduced a higher end TT. But I will say this: with my old TT I kept the stylus clean, and cleaned my records, so even though it was chincy, I had little to no surface noise. BUT the sound felt weak, not present. Almost flat and far away. Cranking up the volume helped.
With my current setup: pioneer receiver, Bose pseudo-vintage pedistal speakers, the Pro-Ject Debut Carbon TT, and this Phono MM Preamp, I have no complaints. The clarity is insane, the presence, depth and warmth are all there. In buying just these two pieces (turntable and preamp), it's like I replaced my whole stereo setup.
For the price, I really don't think you'll find a better preamp. It's very solid, metal and has weight to it, so it's not delicate. It could sustain a drop. The sound quality is great: I get no signal noise whatsoever.
I love this brand, and would recommend them to anyone. And in all honesty, I almost cheaped out and bought a preamp for half the price (albeit with another brand I do like), but I'm glad I didn't. I'll be happy with my current setup for a while.
Overall, right and left channel sound balanced, audio clarity has improved, channel separate is noticeable and build quality is surprisingly good. It feels like an ice cold, heavy, solid piece of metal.

Overall I am very happy with the quality and results.
Enter the Pro-ject Phono Box MM costing less than the repair shop charged me to open up my preamp and tell me that they can't service it. This sturdy metal box, no larger than it needs to be, no annoying lights, no switches, dials, or options, melted into my system and lifted the sound to wear it can be. An unexpected bonus was that record surface noise, already quite low, went completely black (wow).
Thrilled over here. 5 stars.

I wanted to try something solid state to see if it improved the sound quality.
It definetely did the separation and balanced clarity mad it a worthwhile purchase.
I hooked my secondary turntable to the Fosi.
This is a nice sounding pre amp and highly recommend it if you don't want to break the bank.
