## Questions & Answers

**Q: Does computer supply power thru usb when it works as dac or it work on battery power?**
A: Yes, 5K USB DAC gets the power source directly from USB VBUS.
It won't drain any battery power when working as a USB DAC. (Unlike BTR5...)
As you are concerned and asked us, it's crucial for all aspects.

**Q: Can i get full benefit of apple music lossless tracks on iphone 12?**
A: Yes, as long as you use this as a wired connection and with headphones that can reasonably play 16bit/44.1hz quality. Things to keep in mind: 1) The headphone is as good as the DAC, and vice versa. 2) Bluetooth is never really "lossless," but you can get approximates that are likely to fool your ears and thus be the same thing. Using the Qudelix as a bluetooth DAC will not give you "lossless" music output, but it will be very, very good. If you want true "lossless," you have to be wired. 3) On Apple devices, be sure to enable lossless output in Settings for iPad/iOS, or Music preferences AND in the MIDI launcher on Mac. Happy listening!

**Q: How can I pair this divice to a wireless earphones?**
A: It is not made FOR bluetooth earphones—IT IS A BLUETOOTH device itself!  Just plug in wired earphones & they ARE NOW Wireless Earphones when Quedlix 5 is paired with an audio source!

**Q: Is it possible to connect this to a pc via usb, then have the dac stream music to a bt headphone?**
A: Only if the BT headphone can be connected with a cable to the headphones.  Some BT headphones have a jack for a wired connection.
