## Questions & Answers

**Q: Will the USB input charge your input device?**
A: No, the device can be powered through the power connector. USB is an interface as an input device

**Q: Can I connect to a turntable or do I also need a pre amp**
A: I connect to a Bose 5.1 sound system with base woofer and 4-way speakers.  The Bose system is not independently powered, and everything works just fine.

**Q: Is there a model available with bluetooth?**
A: No

**Q: can I connect a cd player to this via the RCA inputs?**
A: Yes you can
In fact you can connect any audio device that is capable of provding 'line out' levels. 
You could connect a record deck but would need a preamplifer between the deck and the amp as the sensitivity of the input is 'line level'
