QP2R USB DAC 

QP2R supports headphone and line outputs, as well as Optical and S/PDIF 

outputs. ( When QP2R is used as a  DAC for digital output, DSD files sampling at 

DSD256 in  your computer  is processed only in DoP mode other than Native 

mode.)  You can press the OK button to disconnect QP2R from the USB connection 

to your computer and then go back to the main menu. 

QP2R USB DAC Feature

What’s new with Questyle QP2R High-res Portable Audio Player is the feature of 

USB DAC, namely, QP2R will be used as a DAC/Headphone Amp when it is 

connected to your computer via a USB cable. Music files in your computer will be 

delivered to QP2R for D/A converting, then to QP2R’s headphone output, which will 

get you much better sounding.
