to stream your music library stored computers to 24bit/96KHz
digital output including RCA coaxial, Optical and I2S.
Secondly QA01 is a stereo analog to digital convertor
interface that provides the way to store your favorite old
tapes and LPs to 24bit/192KHz high quality digital recording
on devices like MD.
QA01 employees TE7022L as the USB interface chip, the native
ASIO and USB2.0support of TE7022E working together with the
sampling clock reforming circuit that reduce jitters to the
minimal.
In order to deliver high quality of sound,each functional
unit is supplied by an independent LDO voltage regulator
chip, and the system can be powered by an external power
supply to get even better performance, the external power
supply overrides the USB supply automatically once the
external power supply powered up.
