COMPARAISON DE PRODUITS BOX X2 BOX X1 BOX X3 BOX X4 BOX X5 P3 P4 Review: Sounds way better than it cost - Fantastic quality little pre-amp. Sounds way better than what it cost Review: Great improvement to sound depth and quality of vinyl output - Having recently setup a Pro-Ject T1 SB turntable to go alongside some of my Sonos speakers, which includes an in-built pre-amp, I noticed a lack of depth to the sound output and in particular, a lack of volume available through the speakers. Having done some research on external 3rd party MM preamps, including Pro-Ject's own products, I found some good reviews of the Fosi Audio X2 Phono Preamp, so ordered it yesterday and it arrived by 10:00 this morning (desertcart at their finest! lol). Anyway, it was completely straight forward to setup using my existing phono cables between the turntable and the preamp, plus a new set from the preamp to the speaker, which I bought separately to ensure I had good quality cables with gold-plated contacts. The sound improvement is fantastic, with each of the three gain settings making a noticeable difference to the depth and quality of the output from the vinyl. I may look into different valves in future, to see how they further affect and/or improve the sound of the music, as suggested in some of the other product reviews on here, however my immediate feedback on this products is that it has been a great buy. ## Features - ❤Exceptional Utra-Low Noise - Converts phono signals to line-level signals with low-noise integrated circuits and high-quality components to remove low-frequency noise to ensure clear sound quality.

Is it normal ?** A: Yes, it’s only meant to be a connection between amps. I use the headphone output to my Mackie Big Knob volume controller. **Q: How do I control the volume with this preamp is there a remote control I have to buy?** A: Theres no volume control on the Boxx1 unfortunately **Q: Can I plug my audio technia atlp. 60x into this preamp as a better choice than the onboard preamp.then plug into my onkyo home cinema receiver?** A: Depends if the receiver has the option of by-passing the onboard preamp with separate inputs **Q: I have a fosi x2 and a douk st-01. i need a headphone socket. can i add an x1 before the x2 ? or between the x2 and st-01 or should i use y cables?** A: Hello. You don't need to add an X1 before X2, you can connect the audio source to the 3.5mm aux input of the BOX X2 and the rca output of the BOX X2 to the rca input of the st-01, you need an rca to rca cable for this connection.
