					Description: 
					 
					QA730U is an 
					asynchronous High Speed USB to digital audio interface that 
					extracts the highest possible audio quality from computer 
					audio sources.  
					 
					The QA730U streams bit perfect audio data up to 24-bit @ 
					192kHz, providing a signal clear, and true to its source. 
					The QA730U will output true, 24-bit audio files and supports 
					all these sample rates: 44.1kHz, 48kHz, 88.2kHz, 96kHz, 
					176.4kHz, 192kHz. 
					 
					The QA730U is finely designed to work within your digital 
					system. Your digital system will function together as parts 
					of an instrument. Your QA730U is built to fit effortlessly 
					into your system, becoming a   bridge   between your computer 
					and your DAC. 
					 
					Great care was taken in the design of the QA730U to isolate 
					the noisy computer/USB environment from the digital audio 
					output. The USB receiver and processing are powered by the 
					computer, while the output line drivers are powered by a 
					separate isolated linear power supply. 
					 
					The QA730U's USB is designed to work with both Apple 
					Macintosh and Windows PC computers. Microsoft Windows PC  s 
					require the included Windows driver which works with Windows 
					XP, Vista and 7 and windows 8 and Windows 10.  
					24bit/192KHz wav 
					and DSD Support 
					 
					QA730U supports Studio Master wav files in 24bit/192KHz and 
					DSD64/1bit/Stereo.  DSD files can be streamed out of 
					the digital output in DoP format.
