## 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.

### ⭐⭐⭐⭐⭐ Rediscovering old friends with the help of a new tool
*by D***D on March 31, 2019*

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!

### ⭐⭐⭐⭐⭐ Love it. Pro-Ject is synonymous with quality.
*by R***T on March 2, 2017*

I couldn't review this for a while because at the time of purchase, it didn't work with my setup. Apparently my cheap-o weak turntable already had a preamp built in.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.

### ⭐⭐⭐⭐⭐ Clean, natural sounding music on my vintage system
*by P***N on September 6, 2022*

I listen to mostly "classical" LPs on a mostly vintage stereo system (circa '89 Thorens TT, Signet tonearm, Magnepan speakers, Hafler amp, cartridge meticulously aligned). The weak link is a lovely 50-year-old McIntosh preamp (mine has a flaky phono stage - left channel dozes off intermittently, bit of hum).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.
