Your cart is empty.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.

Excellent product for the price. The power supply plug comes with adaptors so it can be used outside of North America. Unit works great! No complaints after a week of using it.

I just received this unit today. The external power supply was made for European outlets. (I live in Canada). You should probably order the required outlet adaptor. You can always return it. When I eventually get the working, I'll leave another review. I'm a little disappointed at the moment.This is the other review. I bought an adaptor and everything is up and running. This is a wonderful little unit. I'm not getting any noise or hum at all, just clean music from my turntable to my amp. Everything starts with the preamp and this one was a good purchase. I'm using inexpensive, but shielded, audio cables and keeping them separate from the power cables. You will be very happy with this unit. It's very small and looks as good as it performs.

Had a built in phono preamp in a 2000 dollar amplifier, got a new amplifier with no phono preamp got this as a temporary setup but after using it for a week,the sound is verry good lots of base,super quiet no humm,highs a bit lacking detail,but between this and a 600 dollar one,not worth the 500 extra.My setup rega p3 with exact cartridge, nad m10 v2 amplifier and wharfedale evo 4.4 speakers.

I have a receiver with a phono amp built in. However when I used my turntable (yes grounded), I kept getting a hum through my speakers. I purchased the Project Amp and hooked it up which eliminated my issue. The amp was easy to set up and could not be happier with my purchase.

Easy to set up and works flawlessly. Connected to a Pro-Jet turntable and sounds wonderful. Crisp highs and deep bases. Fantastic dynamic range!

My first phono pre amp I purchased was the Fosi Audio tube pre amp.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.

Aún no lo he usado muchas horas y por tanto no puedo decir nada sobre su durabilidad, pero yo soy de los que desconectan la alimentación con el interruptor de la regleta y supongo que eso ayudará en ese aspecto.La calidad del sonido es excelente con mi cápsula MM y el ruido de fondo es ridículamente bajo. Apenas es perceptible con el volumen del amplificador a 70, hay que estar en completo silencio para notar cuando pones/quitas el mute.Algunas personas se han quejado de mucho ruido de fondo o de que al tiempo de instalarlo a aumentado mucho. Hay que recordar que la señal phono es analógica, de MUY bajo nivel y de alta impedancia, eso obliga a que necesite mucha amplificación para equiparar su nivel con el de la salida de linea y la hace muy sensible a cualquier ruido eléctrico aunque se conecte correctamente la toma de tierra entre el tocadiscos y el preamplificador. Por eso es muy importante como se colocan los cables para eliminar o reducir al máximo ese ruido, alejando todo lo posible el cable phono y la entrada del preamplificador de los cables de alimentación.En mi caso concreto, partiendo de un plato de más de 40 años, le he añadido este preamplificador y un emisor bluetooth 5.3 para poderlo usar sin que esté cerca del equipo de sonido. He montado todo en la parte trasera del plato. Hice una primera prueba para distribuirlos junto con una regleta en la posición que me resultaba más cómoda para encender/apagar las tres cosas. Con esa distribución tenía un ruido de fondo enorme, totalmente inasumible. Cambié la distribución para que coincidiera el cable de salida del plato con la entrada del preamplificador, enrollé y sujete el cable a su lado. En el otro extremo puse la regleta junto a la toma de corriente del plato, y en medio el emisor. Todos los cables recogidos y sujetos para que no se puedan mover y produzcan zumbidos indeseados. El zumbido desapareció y ahora puedo escuchar mis viejos vinilos con el plato en un lugar más cómodo, práctico y sin perder calidad de sonido.

So wie beschrieben. Funktioniert tadellos. Kann nichts bemängeln.

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!

Prodotto acquistato per sostituire il mio vecchio prephono che non scaricava più l'elettricità a terra tanto che ogni volta che toccavo il piatto prendevo la scossa, con questo prephono sono ritornato ad ascoltare i dischi con tranquillità, Consigliatissimo
