Review: Opened up the sound - This perform better than the inbuilt phono stage of the turntable or the onkyo receiver. The voice is warm and pleasent. A good stylus with the phono preamp is a must if you have a turntable.
Review: Works fine but power adapter not suited for UAE - This item does the job with my record player (Fluance RT85) however one little gripe is that the plus is not suitable for UAE/UK - it is a 2 pin plug.

## Questions & Answers

**Q: My turntable has a built-in phono preamp. How do I connect it to the BOX X2?**
A: • If the turntable has a built-in phono preamp, switch it to "Line Out" mode and connect it to the 3.5mm input on the BOX X2. • If the turntable is set to "Phono" mode, connect it to the MM input on the BOX X2 for optimal sound.

**Q: Does the BOX X2 have any built-in tone control? Dose the BOX X2 have bluetooth?**
