Its external DC power supply and vibration-resistant housing ensure interference-free, high-fidelity sound, making it the perfect upgrade for modern turntable setups lacking dedicated phono inputs.

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.

## 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.
